Bandsaw circle cutting jig

This weekend I made a circle jig using the instructions posted on this page . I needed a two foot square piece of 3/4 plywood, four wood screws, a thin nail, a drill press and a table saw. And a bandsaw, otherwise there’s no point.

I made the sliding piece too thin – I tried to make it 3/4 inch on the top surface but I ended up with less than that. It still works but I will need to have a thin blade in the bandsaw – not a problem, really, as I do have a thin blade in it. Also I neglected to note that the Grizzly bandsaw has a little plug sticking out of the table on the right hand side, which I only realised after assembly. Lacking a milling machine I made do with many repetitions on the drill press, making some space for that plug.

I then had to re-assemble one of the sides because there was too much play in the slider, and I was getting rather interesting spirals instead of circles, and it was also bending my blade so I had to abort and fix the issue.

But I’ve already used this jig to make a couple of circles today and also to make quarter-circle corners on a project, so I think it’s definitely worth the $10 of materials and about an hour of labor.

This should work better than my current rig and much more adjustable. Thanks for the post.

Hi DiggerJack,

It’s a 14 inch bandsaw. The size of the table is 14 inches square so I made the total size of the top pieces 14×22 inches and the supporting piece is 14×8 inches.

Elizabeth,
Thanks again. I’m posting my new circle jig based on your post. Mainly to show postings can and do inspire others to get away from the computer and back in the shop.

Jim – it is indeed! Part of me wishes that I’d splurged on the 555X, but the rest of me really likes the saw.

Have your say...
