needs a hole or a disk. Positive, negative its still a circle. Rather than buying a circle jig that is adjustable, make one with the info in this article.

As always when using power provide safety for your senses eyes, ears and nose. There's not any good work arounds when they get hurt.

Hey Newtooth,

I've always call that a "trammel".

I'm afraid that I'm not too impressed with that one. It appears as though the trammel would slip off of its prescribed radius too easily. Having used a router trammel quite a bit myself, I recommend something more like this.

viewtopic.php?f=2&t=32888&p=300014&hilit=router+trammel#p300014

Using a sled for the router on the trammel means that you can easily adjust the radius and expect it to stay where you put it.

Cheers,
Tom
