=== Wheel inspection ===

[[File:Surface-grinder-wheel-inspection.jpg|thumb|right|Tap a wheel with the end of a screwdriver to test its ring]]

<blockquote>When a grinding wheel is received in the shop or removed from storage, it should be inspected closely for damage or cracks. Check a small wheel by suspending it on one finger or with a piece of string. Tap it gently with a light '''nonmetallic''' instrument, such as the handle of a screwdriver. If the wheel does not give a clear ring, discard it.</blockquote>

<blockquote>All wheels do not emit the same tone; a low tone does not necessarily mean a cracked wheel. Wheels are often filled with various resins or greases to modify their cutting action, and resin or grease deadens the tone. Vitrified and silicate wheels emit a clear metallic ring. Resin, rubber, and shellac bonded wheels emit a tone that is less clear. Regardless of the bond, the sound of a cracked wheel is easy to identify.</blockquote>

==== Procedure for wheel inspection ====
# Suspend the wheel on a pin or a shaft that fits through the hole so that it will be easy to turn, but do not mouth the wheel on the grinder. If the wheel is too large to suspend, stand it on a clean, hard surface.
# Imagine a vertical plumb line up the center of the wheel.
# Tap the wheel about 45 degrees on each side of the vertical line, about one or two inches from the wheel’s edge. (Large wheels may tapped on the edge rather than the side of the wheel.)
# Turn the wheel 180 degrees so that the bottom of the wheel is now on top.
# Tap the wheel about 45 degrees on each side of the vertical line again.
# The wheel passes the test if it gives a clear metallic tone when tapped at all four points. If the wheel sounds dead at any of the four points, it is cracked. Do not use it.

=== Operation ===
* The magnetic chuck should never be turned off when the wheel is spinning: if, for some reason, the wheel comes in contact with a part when the chuck is off, it could kick it out, possibly hitting something or someone (at best), or causing a wheel explosion
* The spindle should never be turned on unless the wheel cover is fitted into place: if the wheel explodes when the cover is not fitted, nothing will protect you from the fragments
* It is recommended that the X-axis stops are located such that they will stop the table before its horizontal travel is exceeded, and that the stop plunger is enabled when grinding
** If the table exceeds its horizontal travel, it will hop off its ways, which can potentially cause a wheel crash

=== Work holding ===
* Preparation
** Stone parts & workholding fixtures (e.g. the magnetic chuck, a grinding vice) every time the setup is changed (e.g. when a part is removed from the magnetic chuck for measuring)
** Wipe mating surfaces (e.g. part face, magnetic chuck face) down to remove grit before clamping
** Lap or sand rough (unground) faces before holding them on the magnetic chuck
*** Magnetic holding force is a function of the surface finish of the mating faces (part face & magnetic chuck face)
* Geometry
** Thin parts
*** The field lines loop back about a quarter of an inch above the magnetic chuck face, so care should be taken that parts thinner than that are held securely: make sure they can't be shifted on the mag chuck before grinding
** Tall parts
*** Work holding force is proportional to the contact area
*** Tall parts act as a long lever when the grinding forces (tangential to the wheel, parallel to the grinder travel) act on the top
*** Tall parts are prone to tipping over
**** They can be blocked in with shorter, wider pieces, but a safer route is to clamp them securely to something that isn't at risk of falling over: either in a grinding vice or to a large square
** Everything on the magnetic chuck face should be oriented so that if it does tip over, the part is moved '''away''' from the grinding wheel, not into it; otherwise, it will likely result in a catastrophic crash (a wheel explosion) if the part tipswhile grinding
* Material
** Only ferromagnetic materials can be held directly on the magnetic chuck
** Parts made of any other material need to be held using additional workholding fixtures (e.g. a grinding vice) which are themselves held by the magnetic chuck

=== Health ===
* Dust / grit collection should always be turned on, because you do not want to breathe it
* The operator should never put their hand (or any other body part) anywhere near the wheel when it's spinning
** Even if the wheel is backed off from the magnetic chuck, the wheel should be turned off before parts are picked up off of the magnetic chuck, in case one of the hand-feed wheels is bumped, potentially causing the table to knock a body part into the spinning wheel

[[File:Surface-grinding-wheel-markings.jpg|thumb|right|Wheel type markings]]

<blockquote>Every grinding wheel is marked by the manufacturer with a stencil or a small tag. The manufacturers have worked out a standard system of markings.</blockquote>

=== Wheel Shape ===

[[File:Surface-grinder-heel-shapes.jpg|thumb|right|Wheel shapes]]

{|class="wikitable"
! Shape
! Type nos.
! Description
|-
! Straight
| 1, 5, 7
| Straight wheels are commonly applied to internal, cylindrical, horizontal spindle, surface, tool, and offhand grinding and snagging. The recesses in type numbers 5 and 7 accommodate mounting flanges. Type number 1 wheels from 0.006" to 1/8" thick are used for cutting off stock and slotting.
|-
! Cylinder
| 2
| Cylinder wheels may be arranged for grinding on either the periphery or side of the wheel.
|-
! Tapered
| 4
| Tapered wheels take tapered safety flanges to keep pieces from flying if the wheel is broken while snagging.
|-
! Straight cup
| 6
| The straight cup wheel is used primarily for surface grinding, but can also be used for offhand grinding of flat surfaces. Plain or beveled faces are available.
|-
! Flaring
| 11
| The flaring cup wheel is commonly used for tool grinding. With a resinoid bond, it is useful for snagging. Its face may be plain or beveled.
|-
! Dish
| 12
| The chief use of the dish wheel is in tool work. Its thin edge can be inserted into narrow places, and it is convenient for grinding the faces of form-relieved milling cutters and broaches.
|-
! Saucer
| 13
| The saucer wheel is also known as a saw gummer because it is used for sharpening saws.

<blockquote>Abrasive grains are selected according to the mesh of a sieve through which they are sorted. For example, grain number 40 indicates that the abrasive grain passes through a sieve having approximately 40 meshes to the linear inch. A grinding wheel is designated coarse, medium, or fine according to the size of the individual abrasive grains making up the wheel. The softer and more ductile the material, the coarser the grain size. The larger the amount of stock to be removed, the coarser the grain size. The finer the finish desired, the finer the grain size.</blockquote>

=== Hardness grade ===

<blockquote>The grade of a grinding wheel designates the hardness of the bonded material. A soft wheel is one on which the cutting particles break away rapidly while a hard wheel is one on which the bond successfully opposes this breaking away of the abrasive grain.</blockquote>

<blockquote>Most wheels are graded according to hardness by a letter system. Most manufacturers of grinding abrasive wheels use a letter code ranging from A (very soft) to Z (very hard). Vitrified and silicate bonds usually range from very soft to very hard, shellac and resinoid bonds usually range from very soft to hard, and rubber bonds are limited to the medium to hard range.</blockquote>

<blockquote>The grade of hardness should be selected as carefully as the grain size. A grinding abrasive wheel that is too soft will wear away too rapidly, the abrasive grain will be discarded from the wheel before its useful life is realized. On the other hand, if the wheel is too hard for the job, the abrasive particles will become dull because the bond will not release the abrasive grain, and the wheel’s efficiency will be impaired.</blockquote>

<blockquote>The harder the material, the softer the wheel. The smaller the arc of contact, the harder the grade should be. The arc of contact is the arc, measured along the periphery of the wheel, that is in contact with the work at any instance. It follows that the larger the grinding wheel, the greater the arc of contact and, therefore, a softer wheel can be used. The higher the work speed with relation to the wheel speed, the milder the grinding action and the harder the grade should be.</blockquote>

=== Bonding material ===

<blockquote>The abrasive particles in a grinding wheel are held in place by the bonding agent. The percentage of bond in the wheel determines, to a great extent, the 'hardness' or 'grade' of the wheel. The greater the percentage and strength of the bond, the harder the grinding wheel will be. “Hard” wheels retain the cutting grains longer, while “soft” wheels release the grains quickly. If a grinding wheel is 'too hard' for the job, it will glaze because the bond prevents dulled abrasive particles from being released so new grains can be exposed for cutting. Besides controlling hardness and holding the abrasive, the bond also provides the proper safety factor at running speed. It holds the wheel together while centrifugal force is trying to tear it apart. The most common bonds used in grinding wheels are vitrified, silicate, shellac, resinoid, and rubber.</blockquote>

{|class="wikitable"
! Bond type
! Symbol
! Description
|-
! Vitrified
| V
| The majority of grinding wheels have a vitrified bond. Vitrified bonded wheels are unaffected by heat or cold and are made in a greater range of hardness than any other bond. They adapt to practically all types of grinding with one notable exception: if the wheel is not thick enough, it does not withstand side pressure as in the case of thin cutoff wheels.
|-
! Silicate
| S
| Silicate bond releases the abrasive grains more readily than vitrified bond. Silicate bonded wheels are well suited for grinding where heat must be kept to a minimum, such as grinding edged cutting tools. It is not suited for heavy-duty grinding. Thin cutoff wheels are sometimes made with a shellac bond because it provides fast cool cutting.
|-
! Resin
| B
| Resinoid bond is strong and flexible. It is widely used in snagging wheels (for grinding irregularities from rough castings), which operate at 9,500 SFPM. It is also used in cutoff wheels.
|-
! Rubber
| R
| In rubber-bonded wheels, pure rubber is mixed with sulfur. It is extremely flexible at operating speeds and permits the manufacture of grinding wheels as thin as 0.006 inch for slitting nibs. Most abrasive cutoff machine wheels have a rubber bond.

=== Abrasive structure ===

[[File:Surface-grinding-wheel-structure.jpg|thumb|right|Wheel structure]]

<blockquote>Bond strength of a grinding wheel is not wholly dependent upon the grade of hardness but depends equally on the structure of the wheel, that is, the spacing of the grain or its density. The structure or spacing is measured in number of grains per cubic inch of wheel volume. The softer, tougher, and more ductile the material, the wider the grain spacing. The finer the finish desired, the closer, or more dense, the grain spacing should be.</blockquote>

<blockquote>Most grinding wheels are made of silicon carbide or aluminum oxide, both of which are artificial (manufactured) abrasives. Silicon carbide is extremely hard but brittle. Aluminum oxide is slightly softer but is tougher than silicon carbide. It dulls more quickly, but it does not fracture easily therefore it is better suited for grinding materials of relatively high tensile strength. The tensile strength of material to be ground is the main factor in the selection of the abrasive to be used.</blockquote>

== Wheel selection ==

# First consider the material to be ground and its hardness. These affect the choice of abrasive and grade or hardness of the wheel.
#* Aluminum oxide are best for steels, while silicon carbide abrasives are better suited to grinding cast iron, nonferrous metals and nonmetallic materials.
#* The hardness of the material to be ground also affects choice of the wheel grade or hardness. A harder grade can more easily be used on soft, easily penetrated materials than on hard materials which naturally tend to dull the wheel faster. The softer grades release the dull grains more readily to present new, sharp grains to the work.
# Second factor, in selecting a wheel in the amount of stock to be removed and the finish required. These affect the choice of grit size and bond as follows:
#* A relatively coarse grit size is selected for rapid stock removal without regard for finish as rough grinding; a fine grit should be used where a high finish is desired.
#* Vitrified bonded wheels are generally used where a commercial finish satisfactory. The organic bonds, resinoid, rubber and shellac, produce the highest finish.
# The area of grinding contact between the wheel and the work affects the choice of grit size and grade.
#* A coarse grit is required when the contact area is relatively large, as in surface grinding with cup wheels, cylinders or segments, to provide adequate chip clearance between the abrasive grains. As area of contact becomes smaller and the unit pressure tending to break down the wheel face becomes greater, finer grit wheels should be used.
#* As to the grade or hardness, on large area of contact a soft grade will provide normal breakdown of the wheel, insuring continuous, free-cutting action. A harder grade, on the other hand, is needed to stand up under the increasingly higher unit pressure as the area of contact becomes smaller.
# The severity of the grinding operation affects the choice of abrasive and grade.
#* A tough abrasive like 4A Aluminum Oxide should be used for rough, heavy duty grinding of steel.
#* The milder abrasives like 32 and 38 Aluminum Oxide are best for lighter precision grinding operations on steels and semisteels, while the intermediate 57 and 19 Aluminum Oxide abrasives are used for precision and semiprecision grinding of both mild and hard steels.
#* The severity of the grinding operation also influences the choice of grade. Hard grade provide durable wheels for rough grinding operations such as snagging, while medium and softer grade wheels can be used for precision type operations which are less severe on the wheel.
# The speed at which the grinding wheel is to be operated often dictates the type of bond.
#* Vitrified bonded wheels should not be used at speeds over 6,500 s.f.p.m. With few exceptions, when the speed exceeds this figure, resinoid, rubber or shellac bonded wheels should be used. Note, the safe operating speed shown on the tag, wheel or blotter must never be exceeded.
# Feed rate
#* The higher the feed rate, the greater the grinding pressure is. If the grinding speed of workpiece must be increased, the feed rate will be increased, then the wear of the wheel will be faster. Therefore a harder grinding wheel is required.

== Wheel dressing ==

[[File:Surface-grinder-wheel-dressing.png|thumb|right|The dresser should be angled backwards, in the direction of the wheel, and slightly left-of-center]]

<blockquote>
Grinding wheels wear unevenly under most general grinding operations due to uneven pressure applied to the face of the wheel when it cuts. Also, when the proper wheel has not been used for certain operations, the wheel may become charged with metal particles, or the abrasive grain may become dull before it is broken loose from the wheel bond. In these cases, it is necessary that the wheel be dressed or trued to restore its efficiency and accuracy. 'Dressing' is cutting the face of a grinding wheel to restore its original cutting qualities. 'Truing' is restoring the wheel's concentricity or reforming its cutting face to a desired shape. Both operations are performed with a tool called a 'diamond dresser'. The diamond dresser is the most efficient for truing wheels for precision grinding, where accuracy and high finish are required. A dresser may have a single diamond or multiple diamonds mounted in the end of a round steel shank. Inspect the diamond point frequently for wear. It is the only usable part of the diamond, and is worn away it cannot dress the wheel properly.
</blockquote>

<blockquote>
The whole dressing operation should simulate the grinding operation as much as possible. The grinding wheel usually wears more on the edges, leaving a high spot towards the center. When starting the dressing or truing operation, be certain that the point of the dressing tool touches the highest spot of the wheel first, to prevent the point from digging in. Feed the dresser tool point progressively, 0.001 inch at a time, into the wheel until the sound indicates that the wheel is perfectly true. The rate at which you move the point across the face of the wheel depends upon the grain and the grade of the wheel and the desired finish. A slow feed gives the wheel a fine finish, but if the feed is too slow, the wheel may glaze. A fast feed makes the wheel free cutting, but if the feed is too fast, the dresser will leave tool marks on the wheel. The correct feed can only be found by trial, but a uniform rate of feed should be maintained during any one pass.

Member Storage Registry

2018-02-19T19:34:52Z

Ciacullo2: /* General Work Area Shelves */

Full Members are allowed storage space, and may claim an unoccupied, unclaimed member storage locker or member storage shelf. A locker or shelf could be empty but still be claimed/occupied. Label your shelf or locker adequately.

If you find something on this page that seems inaccurate, Please contact the affected member or the General Area Host. Please do not edit other members' entries.

'''You should use the same name here that you have listed on [https://members.pumpingstationone.org the members site] so that we can verify your membership status. This will help you avoid your storage space getting ticketed and you having to do something about it later.'''

== Catwalk Shelf Registry ==

On the catwalk, numbering starts with the upper left shelf and goes down, then across. The top row is ignored because the opening is too obstructed to be used.

Bridgeport Knee Mill

|arrived=Dec 2013
|doesitwork=yes
|contact=Area Host (Dean Anderson)
|where=Cold Metals
|certification=yes
|hackable=no
|value=~$3000}}

== Description ==
A recent model Knee Mill made by the Bridgeport company. This is the gold-standard small shop manual milling machine in the US. Most other mills of the same size are direct copies of the bridgeport design. This particular machine is a Series I, J-head with a mechanical variable speed drive. The machine has a power quill feed built into the head, in addition to the additional equipment listed below. This machine is capable of facing, surfacing, drilling and slotting in materials ranging from plastics to mild steel. Harder metals may be cut if special cutters and coolant are available. This machine is not equipped with CNC controls, consequently curved paths are limited to circular arcs. These can be cut on pieces that can be mounted on the 8" rotary table or approximated to a desired precision using the simple or smooth arc functions of the DRO.
== Authorization ==
=== This tool requires authorization for use ===

Authorization on this tool requires previous [[Tier 1 Cold Metals Authorization]]. Seek out the volunteer authorizers on the Groups or in person.

=== Resetting the machine and work area after use ===
* Clean up chips
* Turn off DRO, power feed and light

=== Maintenance ===
[[Bridgeport_Knee_Mill_maintenance|bridgeport maintenance page]]

=== Repairs ===
The X-axis handle (opposite the power feed) is missing the spring.

The handle for the Z-axis front lock has snapped off. The rabbit hole is [http://www.icai-online.com/knee-lock-shaft-assembly.html deeper than expected], or may just be a handle that can be removed.

The screw to prevent collets from rotating in the spindle is frequently removed, as some collets won't fit with it in there and it can cause bigger problems if it shears off. This won't be repaired.

The power feed appears to be leaking oil. Parts that we should consider replacing:
* 61 11636413 Seal, Shaft quantity 1
* 72 11630134 Gasket, Cover quantity 1
* 33 11630261 Bearing, Single Row, Loose Fit, quantity 2; these should be available from a bearing distributor

= Authorization for this tool by authorized proctors only =

What this means: this means you cannot get authorized by just anyone who is already authorized. You can only get authorized by a few people, the proctors listed below.

In addition, you should be aware that this authorization is a two-parter; the first session is a classroom session that will cover the software required and introduce you to the essential settings and chip-load calculation, and the second part, scheduled separately, is a hands-on class.

== Authorization Checklist ==

This is here as a checklist for proctors to follow when authorizing people. It can also help remind you of things after you are authorized. Just reading this does not authorizing you.

* How to get authorized
** Watch [http://www.meetup.com/Pumping-Station-One/ the meetup group] for a recurring class on the second Thursday and last Sunday of the month. Sometimes check [https://groups.google.com/forum/#!forum/pumping-station-one the forum] for announcements or ask on the forum if no announcements have been made for a few weeks.

* Authorization group size
** There is no cap to the software instruction preceding the machine usage portion of the class. If you come to this portion it is easier to get fully authorized at a later date.
** 3 machine users - each person will run a job (~1/2 hr each) and everyone will assist each other in completing a job profile and pocket cut. You must be present for the entire authorization

* Safety
** Safety Glasses
** Hearing Protection
** Dust Protection

* What can go wrong (and what to do)

* How does machine work
** Axes
** Motors
** Spindle

* Daily Maintenance
** Spindle bearing warm up.
*** The "C5" warm up routine should be run on the first job of the day. It runs the spindle at 3 speeds for 3 minutes each to warm up the bearings. (When it doubt, warm it up)

* Extended Maintenance
** See maintenance schedule file under documentation.
** Grease the racks
** Use Grease type: Manual states any type is safe there is some in the draw

* Machine Control
** Turn on sequence
*** Log into computer
*** Turn on Shopbot big red and yellow twist switch (see zeroing below)
*** Insert Key and turn to "engaged" position.
*** The VDF should light up, the spindle fan should be on.
*** Start "Shopbot 3" program.
*** Open Tools...Spindle RPM Control menu (to allow RPM control)
**** Make sure collet is tightened or no tool or nut is installed
**** Run the C5 warm up routine
** Jogging
*** Keypad
*** Arrow Keys + Page Up, Page Down (ctrl for fast jog)

* CAM Software
** Vectric V Carve
** Just the basics...separate class for advanced V Carve.
** Online videos

* Running your Job
** Zeroing X & Y
*** With machine off slow push gantry towards X0 until it hits hard stops (optional)
*** Turn on big red switch while still holding gantry.
*** Jog machine away from X0 Y0 so machine will find switches
*** Click X, Y zero button.
** Zeroing Z (top of work piece)
*** Jog over your work piece
*** Place Z zero plate on work piece under the bit
*** Place clip on bit
*** Test connection by touching plate to bit and watch for light #1 to light
*** Click the Z 0 button (it will touch off twice!!!)
*** If Z is critical, you may want to verify that your bit has been zeroed properly by using a "MZ,0" command over the surface you have zeroed the bit to. Repeat zeroing if not correct.

* Waste Board and clamping

* Collets, Bits, Feeds and Speeds
** Feeds and Speeds
*** Use a Cut Load Calculator to determine which feeds and speeds you should be using for your specific bits. An overview is avaialble at: [https://groups.google.com/d/msg/pumping-station-one/vUF3iKRQ9yc/_qNnLXzZ3QcJ]
** Collets
*** We currently have collets for 1/2, 1/4, 3/16 and 1/8" shank bits.
*** Try to keep them clean and store them away from dust between uses. Dust between the gaps will produce runout. The drawer mounted under the Shopbot is the right place to store these items.
*** If the collet nuts are not threading smoothly try cleaning the threads with a small brush, spindle threads as well.
** Bits
*** Use bits designed for the material you are cutting. Don't just steal a bits from the Bridgeport. They won't do a good job and will probably overheat.
*** For cutting out things, use the smallest appropriate bit. Using a 1/2" bit to cutout will just create a lot of mess.

* ShopBot should not be used for...
** Metals other than aluminum
** Cutting anything that requires coolant or lubricant (it will ruin the waste board)
** Ripping lumber (use the table saw)
** Thickness Planning (Use the planner if you can)
** Drilling holes with drill bits (a small end mill works better)

* How to leave the machine (be excellent)
** Machine
*** Home the machine to X0, Y0
*** Turn off both switches
*** Remove Key
*** Remove bit and collet.
*** Place both collet wrenches on top of electronics box
*** clean up work area
*** Smooth out waste board if you puckered it at all.
*** Check if the dust collector needs to be emptied

** Post a picture on our [[Blog]] please!

== Pre-Flight Checklist ==
* Did you home the machine?
* Is the dust collect gate open?
* Are you sure you have the right X, Y orientation for your file and material?
* Did you set the proper X,Y zero for your work piece on the Shopbot.
* Is the correct bit installed and tight?
* Is the key in and turned on?
* Is the dust skirt set right so it does not get smashed.
* Is Z zero set to the work top?
* Is the touch plate and clip returned.
* Is the material properly secured
* Safety glasses, hearing protection on.
* Start the job with the E-Stop ready to hit.
* Turn on dust collector ( I like to wait so I can hear that things sound right on the shopbot before turning on the collector)

|Updated VCarve Post Processor
|Previously, installed new Post Processor to preset an Abort / Retry / Ignore dialog box when the spindle is started but doesn't spin up. Usual culprit is that a job is started when the the interlock is disabled, which results in the non-spinning bit crashing into the workpiece. Abort stops the job. Today, fixed Retry code. If you power on the VFD and the motor start is enabled, the VFD refuses to start. So I've re-programmed the Retry button to stop the VFD, wait 2 seconds, start the VFD, wait 2 more seconds, and check again to see if it is running. The Ignore button actually acts as Retry because we don't want someone clicking through this dialog box and damaging the machine. NOTE: The Aspire PC in the shop also has this Post Processor, but if you use Aspire, VCarve Pro, etc. on your personal computer, you will need the latest Post Processor to support this safety check.

|Updated ShopBot software
|Did upgrade from 3.8.14 to 3.8.26. Installed latest firmware on ShopBot controller. (This was mandatory.) Two features of interest: Fixed occasional erractic behavior after repeated Stops and Resumes (and Nudges or Command Insertions). Reduced liklihood of Keypad lockup.

|Created new VCarve Post Processors
|For drag/engraving bits, it's important that the spindle be turned '''off''' so as to not destroy the bit. Instead of manually modifying the sbp every time to remove the check that the spindle is turned on, I created a couple of new post processors (inches and mm, similar to Ryan's), that explicitly ''turn off'' the spindle. The user is given two opportunities to cancel the job if that is not what he/she wants.

== Outstanding Maintenance Issues ==

=== Lack of True E-Stop ===
As shipped, the ShopBot PRS does not support an Emergency Stop. This could be hacked, but it runs the risk of damaging the machine if engaged in a non-emergency situation. Suggested solution: Installing a 10A double pole 24V coil DIN mount relay, and powering the coil via the 24V supply through a normally closed E-Stop button. One pole will disconnect the 63V stepper motor current. One pole will break the control signal that enables the VFD and will cause the VFD to brake to a stop.

=== Automatic Dust Collection ===
The ShopBot has +5V TTL outputs that could be used to trigger automatic dust collection (when the spindle goes live) and/or a warning light (when the gantry is enabled to move.)

=== Limit Switch Issues ===
Every time you start the ShopBot, it resets itself so that the limit switches are disabled! You can turn them on (if memory serves) with the Values -> Input Switch Assignment menu item. Limit switches are really useful - but they need to be enabled. When they are, they will stop manual jogging when the limit is hit (although pressing the key again will let you continue moving the gantry) and they will also stop a running job (but give you the option of ignoring the limits.)

I found a couple more problems when testing all the limits. When I took the gantry to X maximum, the dust collector hose pulled off! I put it back on, but I'm not sure how stable this is. Also, when I originally set the Y maximum and minimum, I wanted as much spindle travel as possible. But it appears that if you're at the Y max and move in the X direction, you can hit the middle support with the dust collector boot. We've got several inches Y travel beyond the nominal 48", so we may want to look into reducing this to clear the supports.

== Certification ==
==== Safe Operation ====
Description: 
A bench grinder is a machine used to drive an abrasive wheel or wheels. Depending on the grade of the grinding wheel, it may be used for sharpening cutting tools or shaping metal. To avoid accidents, the following operational safety rules must be observed by everyone working on the Pumping Station: One (PS:One) bench grinder. Failure to follow the safety rules may result in a loss of shop privileges. 
 
A Special Note About Fire Safety: 
A bench grind produces a shower of sparks when grinding metal. Know where your nearest fire extinguisher is located before you start grinding. Prior to starting grinding operations inspect the immediate area for, and remove, all flammable materials. Re-inspect the area 30 minutes after the last sparks are generated to ensure that no fires are smoldering. 
 
Start With A Risk Assessment To Ensure A Safe Work Area: 
1. A two-foot perimeter around the grinder should be kept clear of people, debris that impair traction or footing to avoid slips and falls. 
2. 2. ANSI Z87.1 rated safety glasses with side shields or a face shield must be worn. Hearing protection should be worn but is optional for the band saw module itself unless there is other excessive noise in the shop.. 
3. Remove loose fitting clothing, jewelry, and tie back long hair. 
4. Give the work your undivided attention. 
 
Bench Grinder Safety Rules: 
1. Before working with a bench grinder, make sure the tool and its accessories are in the proper working order. 
2. If you are mounting new wheels or changing existing wheels perform a “Ring Test”. Suspend the wheel on a pencil held horizontally through the center of the hole. Tap the wheel lightly with a plastic screwdriver handle, in spots 45 degrees from vertical. If it produces a clear ringing tone it is in good condition. If it sounds dull, replace it. NOTE: The ring test will not work on wheels already mounted on the bench grinder. 
3. Inspect the wheels for hairline cracks, excessive wear or broken edges before using. EVEN IF YOU ARE ONLY USING ONE WHEEL YOU NEED TO INSPECT BOTH WHEELS PRIOR TO POWERING UP! DO NOT USE THE GRINDER IF EITHER WHEEL IS IN POOR CONDITION OR DAMAGED! 
4. Make sure the wheel housing guards are in place. 
5. New grinding wheels should be balanced by dressing and truing to eliminate vibration. 
6. Used wheels should be trued and dressed when worn out of round, or the surface face is clogged or worn smooth. This provides a clean sharp grinding surface and rebalancing of the wheel. Dress the wheel on the face only. Dressing the side of the wheel would cause it to become too thin for safe use. 
7. Don’t operate a grinder unless it is securely mounted to the workbench. 
8. Do not grind on the side of the wheel. 
9. Do not grind soft materials such as wood, rubber or non-ferrous metals such as copper or aluminum. Soft material can clog up the face of the wheels. Dust from soft materials may also accumulate inside the wheel housings and be a potential fire source. 
 
Operational Safety Rules: 
1. Approach your work in the PS:One Shop & on the bench grinder with a safe attitude! 
2. Adjustments need to be made when the grinder is unplugged & stopped. Adjust tool rests 1/8” from the wheels and slightly below center line of the wheels and spark or shatter guards (at the top of the wheel housing guards) 1/2” away from the wheels. Re-adjust these as the wheels wear down to a smaller diameter. 
3. Stand to one side of the wheel when turning on power. Allow the grinding wheel to run at full operating speed for one minute before standing in front of the grinder. DO NOT use a wheel that vibrates. Use your hearing to listen for unusual sounds and put your hand on the bench to feel for excessive vibration. 
4. Bring the object into contact with the grinding wheel slowly and smoothly avoiding impact or bumping motions. 
5. Move the object being ground, back and forth across the face of the wheel only, as this prevents "ruts" or grooves from forming. 
6. Never grind small stock. Do not attempt to grind or sharpen anything that cannot be adequately supported by the tool rest. Use clamping pliers when grinding parts that cannot be held easily by hand. 
7. Do not touch the ground portion of the workpiece until it has cooled. 
8. Keep bystanders a safe distance away from the work area. Anyone entering the work area must wear his/her PPE. 
9. Turn off grinder and wait until it coasts to a complete stop. Never stick an object into the wheel to stop the grinder quicker. Let it stop on it’s own.

== Gas Cost Contribution ==

If you use the shop tank you are required to pay for your gas, gas is priced at '''$5/hour''' of forge use. This may change in the future after we research the cost effectiveness of a larger tank.

== How to get authorized ==

Authorization process will be a spot test on the contents of this page of the wiki and demonstrating that you can safely light the forge.

== Lighting the forge ==

* '''DO NOT ATTEMPT TO LIGHT THE FORGE WITH A MATCH OR LIGHTER (EVEN A LONG LIGHTER/MATCH)'''
* '''MAKE SURE THAT THE GAS HOSE IS NOT TOUCHING THE SIDE OF THE FORGE OR PASSING IN FRONT OF AN OPENING'''

To light the forge:

# Set the sign above the forge to '''HOT'''
# Open the rear door of the space if it is not already open!
# Make sure the burner valves are completely closed!!
# Turn on the valve for the propane tank
# Adjust the pressure regulator on the tank to 10PSI. - If the pressure is too high you will have to open a burner valve slightly to let some pressure out.
# Place a lit piece of paper into the forge
# Making sure the paper is still alight, slightly open the valve for the front burner and allow the forge to light
#* If the burner does not light within a few seconds turn off the valve and reposition the paper
#* If the burner still does not light, check the valve on the propane tank is open far enough
#* If the burner does not light after a second attempt '''DO NOT ATTEMPT TO LIGHT IT AGAIN''' contact the area host for instructions on how to proceed.
# Once the burner is lit adjust the valve until there is a constant feathered flame
#* If you are unable to get a constant flame do not use the forge and contact the area host for further instructions
# If you require the second burner open the valve for the rear burner 1/8th of a turn and allow it to light
# Adjust the valve to get a constant flame as you did for the first

== Important Information Regarding the Forge ==

# Carbon Steel '''ONLY'''! No other material can be placed in the forge.
# '''NO''' galvanized, painted, or otherwise coated steel in the forge.
# '''Do NOT''' poke the sides or back of the forge with your piece. The back hole is slightly higher than the bottom firebrick - please gently place your piece in and then rest it down on the bottom of the forge.
# Make sure the fuel line is '''NEVER''' touching the side of the forge.
# If the torch is sputtering there is something wrong. Try to give it a little more air and more fuel. If that doesn't work, you might be low on fuel. If it continues sputtering turn it off and alert the Area Host.
# Always assume the forge, any nearby tools, and the surrounding area is hot.

== Forge Welding/Flux Use ==

If you are going to use flux for any reason you '''MUST line the interior of the forge with non glazed floor tiles to protect the liner of the forge'''. Anyone caught not using the correct liner will have their certification revoked from the forge.

== Helpful Hints ==

* Directly under the burner is the hottest place in the forge - if you want something heated fast, place it there.
* Your steel will be as hot as it can be when it nearly matches the color of the forge around it.
* Try not to leave tools next to the forge when it is on - they will get very hot.
* Keep your tools cool by quenching often.
* If you have a question or something seems off - contact the area host.
* If you plan on using the forge for a large project you should provide your own tank
* If the tank is less than half full it may freeze during use, if this happens shutdown the forge and allow the tank to warm back up before you light the forge again.
* If the liner of the forge has a crack large enough for gas to enter, stop using the forge let the area host know.
* If you encounter an issue with the forge that requires contacting the area host you must place an out of service sign on the forge including why.

== Certification ==

==== Description ====
Description: 
Angle Grinders are powerful electric motors mounted to a 90deg gearbox. This allows the working tool to be easily manipulated and applied to the work. They typically have a 5/8" arbor, on which you mount cutoff wheels, small grinding wheels, wire wheels, sanding disks, and various other spinny type things. 

== Safe Operation ==
To avoid accidents, the following operational safety rules must be observed by everyone working on the Pumping Station: One (PS:One) angle grinder. Failure to follow the safety rules may result in a loss of shop privileges. 
 
=== Start With A Risk Assessment To Ensure A Safe Work Area: ===
1. Angle grinders typically throw sparks when cutting metal. Make sure that there's nothing flammable in the direction sparks will fly. This includes your clothing. 
2. Make sure your work is properly secured. The workpiece should be in a vice, or heavy enough that it won't move without your intending for it to move. The angle grinder has approximately 2/3 of a horsepower coming from it, so it can, and will, make things move. 
=== Instructions and rules for using the grinder: ===
1. Keep both hands on the grinder. It has two handles for a reason. 
2. Do not remove the safety guard. It can be rotated, but it should not be removed unless a buffing pad is being used. 
3. Do not set the grinder down with the wheel down. If it accidentally gets turned on, it will run away, or worse, run towards you. 
4. Wait until the wheel has stopped spinning before you set the grinder down. 
=== Maintnance and replacement of parts ===
Always return the grinder to its box. 
Spare parts and wheels are stored in the box with the grinder. 
 
Replacing a wheel on the grinder: 
1. unplug the grinder 
2. depress the spindle locking button on the grey section of the grinder 
3. use spanner wrench to loosen the retaining nut 
4. remove and replace accessory disk. (some disks don't use the nut, such as wire wheels.)
