I had some lids to make for my mom for wicker baskets so i came up with this. The top is just 1/4” Luan plywood and the guides and slider are “poplar” that have a 45 degree angle ripped down their length. I waxed the 45s so they things slid nice and good but taped off the part that would be glued to the plywood.

The first picture was taken before I had the holes drilled down the length of the slider that has a pivot pin in. The pin is just a 1” piece of 3/32” thick music wire that was chucked in the drill and polished. There is a small piece of plywood with a PSA sanding disk stuck to it that tightens up against the bottom of the slider to keep it from moving when i cut a circle. This piece is tightened with two knobs that clamp down on some 1/4-20 bolts.

I cut my first circle with it and it turned out great. I may add some more support for the wood being cut by gluing some more stock on top of the plywood but I haven’t decided if that will be necessary yet.

Excellent design.
I too have recently built a circle jig for my band saw to make the lid for my cyclonic separator.
I’m sure these jigs will be used often for many projects.
Well done.

I use my jig for cutting lazy susans.. I have made several hundred and need to update the jig… I mayu take into consideration the double knob clamp… very innovative.

Nice jig : )
I like your design although I would have the base right up to the blade to avoid any possible tear out and also make it wider to support your projects easier. On my own circle cutting jig , I actually sliced thru the base with the blade so it acts like a zero clearance insert to avoid tearout and it supports both the project and the cutoffs. : )

Hey Dusty

I was thinking about a ZCI like support but that would keep me from sliding the bar all the way in for storage. The way it is now I can slide it in and it fits perfectly on the lower shelf of my stand that I got for the bandsaw. The tearout was minimal on red oak but I still might do something like one that swings into place or something.

Then again I been wanting a bigger saw and if I do get one I will probably build a more substantial jig for it.

Consider what the absolute smallest circle you’re ever going to make with your jig , and adjust the length of your bar from there…just my thoughts : )
