bandsaw circle cutting jig

[treesner]

Anyone buy or make a bandsaw jig for cutting circles? I've been making different size circles out of 3/4 ply lately but end up just free handing it and sanding to the line. I know the router circle cutting jig is simple but I tend to get out the router as little as possible and seems like a pain to clamp it so that you don't cut into whats beneath it.

I made this for the one size circle. It's easy enough to add another hole for different sizes. There are heaps of tutorials on youtube about making adjustable jigs. Apart from waiting for glue to dry, it probably took less than 20mins to make. All you need is a bit of ply, hardwood for runners and a screw/piece of metal for alignment.

I just learned that Lennox makes a 3/4 trimester blade.

This one is for large table tops but, the concept is the same if you are doing smaller stuff.  I have even made one-offs for smaller stuff just so I don't have to set the large one up.  Some "t" style miter slot with the mating rail (Peachtree and others) and a scrap of ply.  Fairly crude and awaiting a reason for me to make a version 2.  I assume this one continues to live since a version 2 would only look better and have no functional improvements.

A threaded hole allows the use of large and small 'pins' depending on the mass of the piece to be cut.  The outer threaded holes allow the pivot rail to be locked in position.

Tracks on the bottom lock into the miter slot at the bandsaw and other machines.

Mine is held up by a roller stand and a couple of cleats.  I have since made cutouts in the panel to lessen the weight and it is now pretty usable 'on demand'.  It also functions at other machines for profiling or sanding edges.

Here's a demo using a small piece of scrap.

Nice that looks great, I like the adjustability of it opposed to others I've seen where you just drill a bunch of peg holes

@gee-dub. This is about as simple as I’ve found. Have you revised it or is it still in use?

@Coop - The beast is still in use.  I have many jigs that have hit a version 2, 3, or even 4.  This one still lives as any improvements would only be aesthetic .

Not sure why things happen but about ten minutes after I typed this, I found my jig that i have been looking for for a couple of days. It was hiding in plain sight. But as with many of your ideas, I bet this one falls into at least a couple hands that can use it. Thanks bud!
