I'm too cheap. I've just got a chunk of poplar (1/2 in thick- 4 inch wide) with a hole for a 1-1/8 inch template guide. Probably has 10 different pivot points for the circles I cut most often. The 1/2 inch thickness works out nice, since for holes smaller than the diameter of the base of the router, I can drive a pin into the work piece, set the compass on the pin, then set the router into the compass.

I like using a template guide instead of bolting the router to the jig so I can change back and forth quickly between different routing jobs.

Hi Doug

I'm a cheap SOB also

The last one I made was about the same, it is 30" long with a 3/8" slot down the center of 1/2" thick x 5" wide MDF and a 1" hole in one end , the slot holds a small device with a 1/8" hole and a clamp device to lock it in place.
Drop and cut the hole out quick and easy,popin the 1" brass guide and it's done in a heart beat.
I see many workworkers like to use the band saw but it takes a bit of time to set up the support to hold the stock and the router can do this small job so easy.

I use it to cut the big ones out like round/oval table tops and oval mirror frames, etc.

Sorry Bob but we shall have to agree to disagree on jigs for routing circles. One of the several benefits of Tom's jig design is that it is INFINITELY adjustable. The attached pics show a display stand that I made some time ago where the s.s.tube had to be a very tight fit, 1/16th either way would not have been good enough. I hope that new comers to routing are getting enough information to enable them to experiment and find methods that they feel comfortable with.Harry

Hi Harry

That's what's neat about this forum, we can disagree and still put out jig designs that others can use and try out

Let me make one more small point about the Jasper Jig, you can use it on just about any router, like a small trim router,small air router,small 1HP routers, small plunge routers, etc. some times you don't need alot of power just to make a hole.
