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.

Thx

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

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.
