= Rules =
# Do not move the machine ever.
# Never use the table as a work surface.
# Always have the dust collection on. Turn it on before you plug in the saw and off after you unplug the saw.
# Always check your material on the blade before you spin up the blade. If the light turns red, DO NOT CUT.
# Always check your wood for nails or staples. If you're not sure, check the entire piece with a magnet.
# If you break something, or damage the saw, contact the area host immediately. Don't let others do more damage or hurt themselves by using a broken tool.
# Always dust the entire machine when you are done. Also check the motor compartment after every use and vacuum out as needed.

== Dado Stack ==
Dado stack use requires separate authorization.

SawStop saws support 8″ dado sets only. The optional dado brake cartridge must be used for dado cuts. It has a larger brake pawl designed to stop the multiple blades in a dado set. In addition, you will also need to use a zero-clearance insert specifically for the dado set.

http://www.rockler.com/sawstop-dado-brake-cartridge-for-cns-table-saws

== Sacrificial Fence ==

The Sacrificial Fence requires the dado stack authorization to have been completed.

A sacrificial fence is used in combination with the dado stack to create rebates (grooves) at the edges of boards. Trying to make a rebate at the edge of a board without a sacrificial fence in place will result in damage to the rip fence.

The sacrificial fence is placed on top of the standard table saw rip fence and secured with the screws on the back side. Ensure that the fence is square to the table while tightening the set screws, and that the fence is flush with the front of the rip fence. Then, slide the fence over top of the dado stack, adjusting the fence for the desired rebate width. Adjust the blade height for the desired depth of rebate.

See: https://www.youtube.com/watch?v=JYqvwlbm6B0 beginning at minute 8 for a demonstration of how the sacrificial fence works.

== Blade Brake ==

This saw is equipped with a safety feature that will (hopefully) stop the blade when it contacts something conductive-- like your hand. However, that means you normally can't cut conductive things with this saw or you will trigger the safety brake. This is good if it was your hand in the way, but it also destroys the sawblade and requires installation of a replacement part that costs $70+ every time. And the saw will be down until the replacement can be installed.

According to the owner's manual: "Conductive materials such as aluminum and other metals, carbon fiber materials, '''mirrored acrylic''', carbon-filled materials, etc. will typically '''cause the brake to activate'''." [Emphasis added.]

Other things that may trigger the brake include wet wood, and wood with embedded nails or staples. Lexan and green pressure-treated wood reportedly can also be a problem. That is why the rules instruct you to check your material on the side of the blade before spinning it up, and to check your wood for nails or staples!

== Notes ==
* There's an m8 hole drilled and tapped in the mitre gauge. The post from a magnetic base of our dial indicators thread in. The post may require a spacer so the threads don't stick out (use a stack of washers or a larger-than-m8 nut).
* The right hand table adjusting screw was bent while aligning the table. The table was aligned without it. Aligning the arbor tilt axis will be *really tough* without a replacement. (Part #11 in the cabinet and table exploded diagram in the manual p98)
* The rear rip fence rail has places to put 4 countersunk allen bolts. The left hand bolt screwed into the main table was too long and made contact with an internal table part (probably the rear trunion). It probably pushed the table out of alignment and caused binding while re-aligning the table. That bolt was left out. Don't replace it!

== 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.

=== 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

Tier 1 Cold Metals Authorization

2018-12-13T01:49:22Z

Dgulick: /* People who are Authorized for Cold Metals Tier 1 */ Authorization

[[Category:Cold Metals]]

In the cold metals area we have grouped together authorizations on the non-precision cutting tools into a single authorization. The [[Rockwell drill press]], [[Johnson Bandsaw]], and [[DoAll Bandsaw]] are under the Cold Metals Tier 1 authorization process. The session covers basic operation and safety on the machines.

'''NOTE: Prior to April 2017, the [[Bench Grinder (6in)]], [[Sears Belt Sander|Belt Sander]], and [[DeWalt Chop Saw]] were included in this authorization.'''

Monitor the mailing list for times and dates, or contact one of the listed authorizers.

== How to become a Authorizer ==

We want as many people available to do Cold Metals Tier 1 authorizations as we can get. The idea is to promote safety, and get people used to the sounds that a machine tool cutting well makes.

New authorizers get authorized to authorize others by (1) having some amount of presence in the shop and (2) closely following the "script" during EITHER a "dry-run" authorizing session given to an authorized authorizer -- or conducting a real-live authorizing session while being observed by an authorized authorizer. During such a session, the observing authorizer should _not_ have to speak. Obviously if the new authorizer-to-be has *significant* problems in communication of the content of the "script", the observing authorizer will contribute to the discussion. For the new authorizer-to-be it's a test, not an opportunity for team-teaching.

== Safety ==

=== General Personal Safety, and Consideration of Others ===

You must work safely. Your actions must not threaten the safety of you, of others, or the tools.You should never operate machine tools under the influence of drugs (prescription or otherwise) or alcohol.It is your responsibility to protect your eyes. Safety goggles may be provided in the cage for activities that have the potential to generate flying particles. Activities which may, depending on circumstances generate flying particles include but are not limited to drilling, sawing, lathing, milling, hammering, chiseling, grinding, and belt sanding. Don't use goggles which are dirty or fogged-up. If cleaning is required cleansing pads may be available in the cage. To clean your goggles, all surfaces that have contact with the skin must be wiped down. The lens should be wiped down, both front and inside. If you choose to use purchase your own goggles be sure they are rated for labeled z87 (this should be written or stamped on the side of all goggles) and have side shields.Disposable earplugs may be supplied in the cage. Follow the instructions on the dispenser. They are surprisingly more effective if you do. Many types of Personal Protective Equipment (PPE) are not effective if used improperly. If you don't know whether or how to use your protective equipment, read the instructions.Because of cost and hygiene problems, PS:1 cannot be depended upon to stock dust masks/respirators. If your work has the potential to generate dusts, mists, or vapors, you may proceed only by following these rules:

# Get your own respiratory protection. Ace Hardware has many types. Make sure the mask or filter is really for the substance confronting you. Do not, for instance, use a paper dust mask for organic paint fumes. Follow the mask manufacturer's instructions.
# Work in the back dock when possible, or with an exhaust fan on.
# If it is necessary to work in the main shop be sure you aren't inflicting your fumes or dust on someone else. It would be excellent if you as the fume generator waits until no one is present who could be harmed or inconvenienced by your activities.

When using power tools, remove gloves, watches, jewelry, and roll up your sleeves. Keep your hair tied back and tucked away. This is especially true for the drill presses, mill, and lathe. Tools with moving parts can injure your hands or catch your hair and pull your head into the machine. Gloves and loose clothing can also get caught in moving machinery. Never put your hand in the vicinity of any moving part of any machine. When adjusting the speed of a belt-driven machine (drill press, lathe, mill or other step-pulley drive) unplug the machine before putting your hands into the drive belts. Every Time.If in using any machine that cuts material, you cannot see a cut in progress because of chips or dust produced by the cutting process, a chip brush to clear the work zone -- never use your hands while the tool is on.PS:1 keeps fire extinguishers and first aid supplies on hand. It would be good to familiarize yourself with their locations before you begin your work.

It is best to not work alone in the shop while using machine tools. If you are hurt and cannot dial 911, another person in the space could do that for you. Use the right tool for the job. Incorrect tool usage produces bad results, and can be detrimental to you, your work, and the tools.Knowing a tool is knowing how it works. For instance, power tools make different sounds when they are working. Some sounds are HAPPY and some sounds are SAD. If you don't know how a tool should work, in spite of the demonstration given with this authorization, ask somebody who does know.

=== Safe and Proper Use of the Power Tools ===
This is not an instructional guide to being a machinist. For skill development in using tools in fabrication, you should take a class of some kind and practice, practice, practice. In this authorization, you will be shown only the basic operation of the tools. The purpose of these minimal illustrations of technique is so that you might have some idea of the types of things the tools are capable of. Authorization gives you permission to use the tools. Authorization to use the tools is not a certification of your competence.

== Tool use ==

=== [[Johnson Bandsaw|Horizontal Bandsaw]] ===

The horizontal bandsaw is only for cutting metals.

Clamp your work securely in the vise. Be sure that the work cannot rotate or flip around in the vise when the saw is pulling the blade through the cut. Close the blade guides to the minimum distance that will (1) clear the workpiece and (2) not interfere with the movement of the saw at the bottom end of its travel.

Set the force-control weight to apply proper pressure to the cut. In most cases, this is at minimum. (Closer to the motor is less cut force). Open the hydraulic valve to produce a good feed rate. If the blade seems like it's starting to snag the workpiece or clog the teeth, take a lighter cut by decreasing the feed rate. If the saw is not producing a chip, increase the feed rate. Unless there is a reason to be taking a very light cut, the sound of the saw teeth should be consistent during the entire rotation of the blade. Except when taking a very light cut, the sound of the saw teeth contacting the material should be consistent and chips should form at an even rate. Using coolant helps to preserve blade life, and increase the speed and quality of the cut. It also makes a mess.

A major cause of blade breakage is thin workpieces snagging the saw blade teeth. Snagging causes teeth to be broken and can also cause the blade to stall or come off the wheels. Check the blade for missing teeth before using the saw. A blade with missing teeth is usually not fit for use. Using a fine pitch blade on soft materials like aluminum can clog the teeth and cause the blade to grab the work and stall. Be sure the chips are clearing the teeth. If not, use coolant or a wire brush to push the chips from the teeth. Using a coarse blade on steel will cause the teeth to snag on the work and break off. Turning the saw off (stopping the motor) while the saw is in a cut can cause broken teeth. Any problem that can break a tooth can also cause the blade to come off the wheels. Use the right blade for the work. Trying to mediate a cut on the horizontal bandsaw can cause saw blade teeth to be knocked off the blade; set the saw to lower the blade slowly into the work and then let go. Be gentle with the hydraulic valve. It only requires a feather touch to turn it. Over-torquing the valve handle can damage the valve. If your workpiece gets snagged and stuck on the blade, stop the saw immediately. Unplug the saw, then try to pull the workpiece straight down off the blade.

To free the stuck workpiece, use a rocking or wiggling motion, in-line with the axis of the blade. Don't twist the blade. A bend or kink ruins the blade. If you still can't get your workpiece off the blade, don't force it. Tag the saw as “out of order” and post a message to the list saying “The blade on the horizontal bandsaw is stuck. Could someone please un-stick it.” If the blade comes off the wheels, tag the saw and post the problem to the list.
