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.
