Circle Cutting Jig

I needed a jig to make a lazy susan, my blog is at;
http://lumberjocks.com/jocks/Grumpy/blog/6612
This jig was not my design but came from an article in a magazine. It is fairly simple & I thought it might be worth sharing.
There are 3 wooden components & a handful of metal bits.

A 1/4”X6” disc can be stuck to the item you want to shape or a 1/4 pin can be screwed into a hole in the centre of the item as in the above photo.
A 4 1/2”X 1/2” piece of desired length is then needed to mount the router on. The router is actually mounted on a separate piece of shaped wood at the end.
Photobucket
A 1/4” slot runs along the centre of the longer piece & a 1 1/4” groove is cut on the under side.

I used a metal piece to act as a pivot & also act as a slider along the groove in the longer piece.

The white pieces of tape under the router base was added for this cut to adjust the height because double sided tape was used under the centre piece.
Thats all folks.

That is a really nice jig. I made a quick one before but I put new screw holes in it each time a do a new size circle and I also drill a hole in my work piece. Thanks for sharing, I may try to build one sometimes.

I built one of these a couple years ago but didn’t get it quite right. Thanks for sharing.

Grumpy: It looks great. I like the idea of using double faced tape to hold the center board in place and not having to drill into your piece.

I see you splurged and used some of your local high priced Australian woods for the slide bar.

Good Thought, made something similar when my Class made 40 round tables for a food service.

Odie, I thought you knew. It’s a halo making jig in case you break yours. LOL
