Circle cutting jig for bandsaw

I needed to cut some 21” circles from plywood for a lazy susan cabinet for my kitchen project. I debated between using a router with straight bit and router base add on, or making a jig for the band saw. The band saw won out, mostly because I find holding down the workpiece for a round router cut a PITA.

So, I made this. I comes from some designs that I’ve seen here and there, and some commercial jigs I’ve seen as well. But, I didn’t follow any of those closely, I just picked up some scraps and put this together in about an hour.

It features an adjustable center, with a block that rides inside a shallow dado to keep it tight and aligned. At first I was going to drill some holes in the edge of the band saw table, but the clamps worked just fine, so I think I’ll leave it as is.

This one has a range of about 9” to 22” diameter. I could make a larger one for larger circles if needed. With my new Woodslicer 3-4 tpi blade, it worked like a champ. I’m pleased.

doncutlip: Nothing fancy: its a Grizzly G0555P 14” Polar Bear Series. I’ve had it for a few months, and love it. I just added the 6” riser block and the Highland Woodworking Wood Slicer blade. I resawed some 1 1/2” red oak to use as a strip to wrap around the circle shelf for an edge, and it went through it with no wavering and no problem.

Nice jig and good idea. I have the same band saw and really like it. I will be ordering the riser block this week as all my old blades are finally worn out and I can buy the bigger ones needed without wasting then ones I have now.

Would love to hear some demensions on this will be putting in my fav’s as well.

Necessity is the mother of invention.
Great fixture and a whole lot faster, cleaner and safer than any router setup.

Looks like a nice set up : )

May I ask why such a long center pin is being used ?
Example :
I use a pin that is only half an inch long. 1/4” goes into my jig and the other 1/4” goes into a shallow 1/4” hole , drilled in the center of my circle.
Maybe you cut several circles at once , and the through hole doesn’t matter ?

Dusty56: the simple answer is, “that’s how long the nail is.” For the lazy susan, I’m cutting out a 3/4” hole anyway, so a long pin isn’t a big deal. But if I were doing a small table top, where a through hole would be bad, I could trim the nail off to be short like you suggest, and not go through the work.

Great jig. I’m putting this in my favorites. I’d love to see a blog on “how to”, maybe with some dimensions.

Good design. Since it doesn’t lay on top of the table it doesn’t reduce the saw’s total cutting height. Also relatively small so it can be stored and mounted easily when needed. And….I’ve got just the scraps needed to build one. Thanks!
