I'm thinking about getting a circle jig for my router, since my jig saw abilities seem to be getting awful rusty.

I saw these

What kind of bit do you need?

Jasper sells a jig that will go from around 2" out to around 18". I have one of the first ones that you linked (the second link doesn't work) and a larger one. I personally use a 1/4" spiral upcut (looks like an endmill) bit. Much quieter than a straight-cut and does a much better job of applying the cutting forces to the piece being cut and allows you to cut some really thin-walled rings. I've done 1/8" wall thickness rings in 3/4" MDF without breaking them.

1/8" is CRAZY!

so this:

I have the pair of Jasper jigs. And yes, that is the bit. Word of caution: check collet tightness regularly like before each cut. The cutting force is up which pulls the bit into the work. If the collet isn't tight or is worn, the bit will be pulled from the collet and through the work and backing board into the table. Don't ask me how I know...

heh, I'll make sure it's tight. I just spent 45 minutes digging out the router, looking up the right part numbers, only to go back and read " and all Sears, Ryobi and Makita models. Made in the U.S.A. "

I've got the ryobi R1801M1, R181FB1

I diy'ed a circle jig

I just broke my Jasper jig (mounting hole broke out). I am going to do the same, but I'll just be copying the jasper's hole layout.

what are you guys making them out of

wood.

If I had money to toss away, aluminum.

lol alright alright
