a few left over scraps, some miter track and miter slot, two set screws, a nail and two bolts to lock it in the table’s miter slot. Works like a charm and can make circles from small to in excess of 40” radius. Just hang it on the wall when not in use. Thanks for looking.

This WILL be copied! I’ve been looking around for something like this and they are all more expensive than I’m willing to pay!

Looks great. I really like your idea for the sliding adjustment.

Very interesting. I built one a little differently but I like some aspects of yours very well. I made my jig so it slide in the miter slot with a stop to limit the travel. This allows you to start out with a square board and slide the jig and board into the blade before rotating the board. I’m guessing with your jig that you start out with a large board and make a spiral cut until you reach the desired diameter? Maybe I have missed some thing.

I live the aluminum guide, how does it lock?

Mork, the sliding guide/center point is locked in place with two set screws that are threaded into the miter track. Look close at the third and last picture, hopefully you can see them there.

So do you trim the board to fit between the pin and the blade before you start cutting the circle?

Mork, I make a straight cut in to a tangent point on the table saw. Then slide it up and in place on the bandsaw, lock it on the pin, start the saw and cut the circle. Hope this helps.
