Crosscutting with a Circular Saw

Introduction: Using the hand held circular saw to quickly process stock into more convenient sized (i.e. safer) blanks for a batch of panels...

Circular Saw Safety
  • Kickback can occur - when front tooth makes contact with the offcut side of the cut and the back tooth makes contact with the “infeed” side simultaneously (i.e. the saw gets shifted crooked in the saw kerf)
    • Kickback on a Circular Saw will often cause the saw to move rather than just the wood - it can come back at you...
  • Always support the offcut
    • I like the the Lee Valley Supports
    • Allows me to support or deflect long and short offcuts easily
  • Remember to protect your feet from offcuts that drop unexpectedly
  • Verify before you cut that NOTHING is obstructing the path of the saw blade
    • Like a support....
  • Clamp infeed side of stock securely
  • Hearing protection and Dust Filtration

The First Cut
  • Cut off end of board
    • Remove any stock with checks off the end
      • Checks = thin cracks that develop at the ends when lumber is dried
      • Good test of saw set up and depth of cut
  • Donʼt want to cut so shallow that the blade does not fully cut through the board
    • Attempting to cut a groove will increase your chance of kickback to almost 100%
  • Cut must be straight but does not have to be square to the edges of the board
    • You can do this free hand, without jigs or fences
  • Note to Self: Next time I plan to cut 2+” old growth walnut, I might need to upgrade to a larger hand held saw
    • You donʼt want the saw bogging down as much as you hear in the podcast...

Mark Kicks Back!
  • I get a kickback on the saw - all according to plan, I assure you....right... Winking
    • This is what happens when the blade doesnʼt clear the bottom of the stock
    • Oops....

More Cuts
  • More of the same
  • Technique Tip - With the power off, line up to the cut and press the blade forward until it contacts the wood, then back off - it is now safe to press the power trigger and start the cut with the blade spinning before it touches any wood
  • Note how well the Lee Valley supports the offcut for this operation
Upcoming

We will be following these panels through all the steps to process into panels for my exterior doors...
