Table Saw Introduction: Difference between revisions

Revision as of 09:31, 3 June 2018

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)
  
  DO NOT use both fences at once!
- 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
