Sheet Metal Work

Sheet Metal Work

  1. Large sheets can be unwieldy. Use C-clamps has handles.
  2. Remove slivers, commonly called fish hooks from edges of sheets.
  3. When chiseling, riveting, grooving, or hand punching, strike the tool squarely with the hammer.
  4. Use care in carrying and using the scriber.
  5. Avoid sliding sheet metal through the hands.
  6. Use corner guards or other devices to protect people using aisles or work areas where large sheets protrude. Beware of corners and edges.
  7. Never wear gloves around rotary machinery.
  8. Guard against shooting the rivet gun by accident. Point it at the floor.
  9. Punch rather than drill large holes in sheet stock.

Sheet Metal Brake

  1. Keep your fingers clear of the mouth of the machine when closing down on the metal.
  2. Use care when inserting or removing sharp-edged sheets.
  3. Make certain counter weight bars do not strike others while moving.
  4. Get assistance when bending large thick material to avoid back strain.
  5. Keep fingers out of the pinch area as the metal is bent, especially on maximum capacity bends.

Buffer

  1. Always buff using the bottom half of the wheel (below center).
  2. USe extra care around openings, corners, or other areas where the wheel can grab and throw the work.
  3. Exercise caution to avoid overheating and burns on the hands.
  4. Avoid allowing the work to become cramped between the wheel and the machine, the wall, or some other object. Freedom of movement is essential to avoid catching.
  5. Make sure the wheel diameter is appropriate for the job.
  6. Never use a rag because the work heats up and rags can catch in revolving arbors.
  7. Always stand to one side of the wheel when applying compound.

Power Hack Saw

  1. Make sure the action of the saw cannot crowd or injure those in front of the moving frame. Stand clear!
  2. Do not reach under the frame of blade when in the raised position.
  3. Make the file cuts on sharp edged objects or angular material so the blade may proceed to work properly.
  4. Keep blades and stock right.
  5. Support end of long stock in a positive manner so blade will not be pinched.
  6. Do not bear down on the saw frame.
  7. Keep hands clear of the mechanism while in operation.
  8. Clean, oil, and adjust when machine has fully stopped.
  9. Do not attempt to cut small pieces in one side of the vise jaws unless a piece of equal size is in the opposite end of the vise, keeping jaws parallel.
  10. Never use a new blade in an old saw kerf.
  11. Install new blades with teeth pointing in the proper direction.
  12. Lower the frame slowly on the work. A sudden drop can shatter a blade.
