Plymouth State University Woodshop

GENERAL RULES

Prof. Phil Lonergan

  • Use the woodshop only when alert, rested and focused. Under no circumstances attempt to use machinery when your judgment is impaired or you are ill, under the effects of medication, drugs or alcohol, or sleep deprivation. No smoking or eating is allowed in the woodshop.
  • Prepare yourself for the use of machinery by securing your clothing, hair and jewelry. Also outfit yourself with appropriate hearing protection, gloves, goggles and personal protective equipment. See to it that all necessary aids, such as push sticks, saw horses, hold-downs, guide fences, or someone to help are within reach or their proper place. ALL GUARDS MUST BE USED. Safety eyeglasses or goggles should also be worn when doing some bench work such as chipping or cutting wood, or when working with materials corrosive to eyes such as solvents, varnishes, or hardeners.
  • Dust collection and ventilation systems have been provided for your protection. You must engage these systems when working on projects.
  • Approach any woodworking machine, hand-held or stationary, with respect, which begins with a thorough examination of the equipment before using it.
  • Keep your attention focused on both the machine and on the operation you wish to perform with it.
  • Never distract or talk to someone who is operating a machine, or allow them to distract or talk to you while you are in the process of using equipment. If you must pass by someone using equipment, approach them head-on so they may see you coming and not be startled.
  • Be alert for any unusual sounds, loose parts, dull blades, poor adjustments, when turning on or operating a machine. Correct the situation before continuing to use the machine. Never force a machine to do work. Report any electrical or mechanical hazards to the woodshop attendant or instructor immediately.
  • Clean up scrap wood, sawdust when finished with an operation. Return the machine to a state of readiness for the next person to use. Also return all hand-held machines to their proper storage area.
  • If you have any question about the use or operation of a machine, ask for assistance before going ahead with your work.
  • First Aid equipment has been provided. Faculty are responsible for keeping it replenished.  All accidents, no matter how minor, must be reported to the woodshop attendant, who is then required to notify the instructor.  ALL accidents must be recorded on an official Accident Form and filed by the Head of the sculpture program.
  • Should symptoms of a health problem or illness appear and persist, report the matter to your instructor and go to the Heath Center for assistance.

 

SAFETY REGULATIONS FOR SPECIFIC EQUIPMENT IN THE WOODSHOP

TABLE SAW

  • Always wear safety goggles, hearing protection, and use the dust collection system. Also, do not wear loose or dangling clothing and jewelry.
  • Clean the table of the machine and the floor around the saw before beginning work, and then again when you are finished.
  • Set the height of the blade ¼ inch above the height of the wood.  Position the blade guard ¼ inch above wood.  Set and lock the fence.  Be sure the wood is well back from the blade before starting the saw.  Use only stock that is free of dirt, paint, nails, loose knots, splits and warps. Also, attempting to rip short, narrow or thin wood invites trouble.
  • Make sure that any necessary aids such as a push stick, push blocks, or rollers to catch outgoing wood are ready before beginning an operation. If a person is going to help you cut a large piece of stock, be sure they only support the stock and do not attempt to push or pull it. YOU, the operator, must control the feed and direction of the cut.
  • Be certain the blade to be used is sharp and the proper type for the operation.
  • Stand to one side of the blade, and never reach across, behind or beyond the blade while cutting. Again, your hands should never be IN LINE with the cutting blade. Maintain a four-inch margin of safety: Do not let your hands come closer than four inches from the blade. USE the push stick.
  • Be sure no one is standing in a direct line behind the saw.
  • Always use either the rip fence or the miter gauge when cutting. NEVER CUT STOCK FREEHAND. When setting the rip fence, make sure that the fence locks parallel to the blade. Otherwise the wood can bind and kick back. Never use the miter gauge in combination with the rip fence unless a clearance block is used. Never try to support both pieces on opposing sides of the saw blade when using the miter gauge; support the portion positioned against the gauge side only. When ripping, always support the portion of your piece that is in between the rip fence and the blade.
  • If you tilt the blade or change the miter gauge, return them to their original position after using the saw.
  • When making a cut, make sure you pass the stock completely past the blade as you finish your cut. NEVER BACK UP STOCK ONCE YOU HAVE PROCEEDED WITH A CUT. If need be, stop, and shut the machine down. Always turn the saw off before attempting to remove scrap.
  • Never talk to anyone or let them distract you while the saw is running. Keep your attention focused on your work.


BANDSAW

  • Always wear safety goggles, hearing protection, and use the dust collection system. Secure all loose clothing, hair and hanging jewelry.
  • Clean the table and the area around the bandsaw before beginning work and when you are finished.
  • Saw only stock which is free of dirt, paint, nails, splits, warps and loose knots.
  • Make all adjustments to the machine before turning it on. Never open the wheel enclosure doors while the machine is in operation. Adjust the upper guide post so that it is no more than 1/4 inch above the work.
  • If the blade is not tracking properly or needs adjustment stop the machine and see the instructor or a woodshop attendant. Do not use a dull blade.
  • Be extremely cautious of the exposed blade. Keep fingers clear. Never allow your hands or fingers to be IN LINE with the blade. Make sure your fingers are out of the way as you near the end of a cut.
  • Avoid backing out of saw cuts. You could pull the blade off the wheel.
  • If a blade breaks, step back quickly, turn off the saw, report to the instructor or woodshop attendant.
  • Clean up.

12″ COMPOUND MITER SAW/MITER SAW SAFETY RULES

  • NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don’t leave tool until it comes to a complete stop.
  • DO NOT OPERATE ELECTRIC TOOLS NEAR FLAMMABLE LIQUIDS OR IN GASEOUS OR EXPLOSIVE ATMOSPHERES. Motors in these tools may spark and ignite fumes.
  • DO-Make certain the blade rotates in the correct direction and that the teeth at the bottom of the blade are pointing to the rear of the miter saw.
  • DO-Be sure all clamp handles are tight before starting any operation.
  • DO- Keep saw blade sharp and properly set.
  • DO-Use blade guards at all times.
  • DO-Keep hands out of path of saw blade.
  • DO-Shut off power, disconnect cord from power source and wait for saw blade to stop before servicing or adjusting tool.
  • DO-Support long work with an outboard tool rest.
  • DON’T-Operate unless all clamp handles are tight.
  • DON’T- Use blades larger or smaller than those which are recommended.
  • DON’T- Wedge anything against fan to hold motor shaft.
  • DON’T-Force cutting action. (Stalling or partial stalling of motor can cause major damage. Allow motor to reach full speed before cutting.)
  • DON’T- Cut ferrous metals (Those with any iron or steel content) or any masonry.
  • DON’T-Allow anyone to stand behind saw.
  • DON’T-Place either hand in the blade area when the saw is connected to the power source.
  • DON’T-Use blades rated less than 4600 R.P.M.
  • DON’T-Operate saw without guards in place or perform any operation freehand.
  • DON’T-Reach around or behind saw blade.
  • DO NOT – Reach underneath the saw unless it is turned off and unplugged. The saw blade is exposed on the underside of the saw.
  • DO NOT – Move either hand from saw or workpiece or raise arm until blade has stopped.

 

NEVER PERFORM ANY OPERATION FREEHAND. NEVER CROSS ARMS IN FRONT OF BLADE. THINK! YOU CAN PREVENT ACCIDENTS.

 

DO NOT OPERATE SAW WITHOUT GUARDS IN PLACE. NEVER REACH IN BACK OF SAW BLADE. ALWAYS WEAR EYE PROTECTION. SHUT OFF POWER AND WAIT FOR BLADE TO STOP BEFORE SERVICING, ADJUSTING TOOL, OR MOVING HANDS.
