So I’m a bit of a lazy dude. Don’t get me wrong I love a good project or jig or art piece but sometimes I need something and I need it now, and I just don’t want to spend time making it nice.
Soooooooooooo this is what I do when I need a zero clearance insert and no time to make one, I’m sure you have all done something similar, maybe you can post a pic or description of your quick fix too.
Basically I get the fence lined up with the distance I need away from the blade and lock it down. Then grab a large enough piece of 1/4” ply and clamp it down over the blade and up flush against the fence. Notice the scap board under saw to make clamp work better. Make sure your blade is lowered all the way. When clamped down good turn on the saw and slowly raise the blade so it cuts into and thru the 1/4” ply. I raise it enough by eyball then shut off the saw to get fine measurements, repeat until its where it needs to be.
Walla zero clearance insert err or over-sert err on top of piece err scrap to not cut yourself err Whatever you get the drift LOL
Thanks for checking it out
