My first posted project is two jigs for my circular saw. The first is a zero clearance guide for sawing straight cuts in panels up to 50” long. It consists of a base of 1/4” hardboard to which I attached a 2” strip of 1/2” Baltic Birch plywood. The strip was positioned slightly farther from the edge of the hardboard then the distance between the edge of the circular saw plate and the blade. The strip was glued and screwed to the hardboard base. I then ran the saw down the hardboard for a zero clearance cut.

The second jig is a square cross cut jig for the circular saw. It will allow me to make square cuts on 30” panels. Again I glued and fastened a 2” strip to the hardboard and sawed it for a zero clearance cut. I then fastened another strip to the bottom of the assemble for the fence. I squared up the fence using the five cut method. I got it to within 0.005” over 24”. I don’t really have anything to get closer than that.

For some reason, the plywood I am using bows slightly when cut into thin strips. For this reason I had to plane and sand on edge of all of the strips. This was the biggest effort in constructing these jigs.

I used these two jigs to cut and square up a piece of plywood for a router table I am constructing. After truing up all of the edges, I measured the diagonal distances and they match to better tan 1/32”.

I added a photo of how the crosscut jig works. In the last photo, a piece of white peg board is in position to be cut.

Thanks for posting your set of jigs. I can’t quite visualize how you would use the second jig (square cross-cut jig)

I’m really curious about it because I am helping my son start his own hobby ww shop, and all he has right now is a circular saw. I’d like to show him that with a little ingenuity you can make cool stuff even with just a CC.

If possible, could you post another picture with jig#2 being used?
