Table Saw Introduction

From CoMakingSpace Wiki

This is the content required for an introduction to our table saw - reading this does NOT replace the mandatory session with a tutor! It will make it a lot quicker though ;-)

Let's begin! First off, make sure you have read the machine's manual.

Safety

Dangers

  • sawdust and small splinters can fly towards the operator
  • sharp and rotating exposed blade - will keep spinning for a bit after turning the power off!
  • kickback - if the workpiece is pressed against the blade's side, it can be thrown towards the operator!

Precautions

  • wear personal protection
    • definitely goggles and ear defenders!
    • dust mask: depending on the material you are cutting
    • gloves: make an informed decision
      • some sources say you should wear them to protect yourself against splinters which could surprise you and make your hand flinch in a dangerous position
      • others prohibit the use of gloves as your entire hand could be dragged into the blade if one gets caught
  • your hands need to stay well clear (at least a hand's width) of the blade at all times - use a push stick if you have something small to cut!
  • height of the blade: make an informed decision
    • high blade: cuts "down", not pushing against you - makes the saw easier to use and leads to less of a difference between cut distances on top and bottom BUT it exposes a lot of the dangerous blade
    • low blade: lower risk of serious injury (could cut into your finger, not as easily trough it) but you have to push the workpiece harder
  • prevent kickback:
    • never use both fences at once (option: fence + stop block which ends before the blade begins)
    • never remove the splitter and check that it is in line with the saw blade
    • make sure the parallel fence is in fact parallel
  • stand on the side where you can support the main part of your workpiece (usually the left)
  • give the saw time to start up before touching the blade with your workpiece!
  • make sure all screws (parallel fence, outfeed table) are tightened

Practical Demonstration

  • parallel fence: three options depending on the desired distance
  • foot switch as the preferred "off" option
  • practice cut with miter fence & parallel fence
