Square Up Bigfoot - 08/25/13 05:06 PM
I’m cutting some half lap joints in the ends of 4x8 beams, so each notch is 3 ½” wide x 3 ¾” deep. I’ve always used my Bigfoot circular saw, made repeated cross cuts using a saw guide then clean up with chisel.
The problem I’m having is the cuts aren’t always square, even after spending ½ an hour setting the saw square! I test for square by cross cutting a 3 ½” wide piece, flipping one piece over and seeing if they both line up where they butt.
Question is, how do you square up a circular saw, and then test for being square?
Is there a better, more accurate way to cut these half laps besides investing in an expensive new power tool? I was (briefly) thinking about putting a 12” blade on my 10” radial arm (if I can find the correct arbor size in a 12” blade) but know this would be plain stupid without a guard!
