That looks nice, Brad. Are the holes standard PC base? Looks like it is made out of aluminum or something.

That looks really nice. How does it work?

I will let Brad weigh in, but you put a nail or screw in the hole on the arm and that acts as a pivot. You secure the router to the other end, center the bit in the hole and then you change the diameter of the cirlce with the knob and move the router closer or farther aware from the pivot. Lock it down when you have the diameter you want and away you go.

yup, that’s exactly it. I put a roll pin in the end so I drill a pilot hole and away you go. Standard PC holes that are going to get the treatment for the bosch.

Definitely a useful jig to have. I saw one at Rockler a while back and decided to make one from some stuff lying around the shop.
Also made a table mounted router version. I’ll post a pic if I can locate one. The table mounted version relies on a straight bit with a bearing.July 13, 2014 at 8:43 pm #161476
I found it. It’s a JP Thein design…
I’ve built both router jigs and a variation of his separator from the information on his website. IMO, it’s worth the read.
Edit: correction, JP Thein apparently did not post plans on how to make a circle jig for a hand held router, just a table mounted version.

I have seen the perfect circle a few time. Always tell myself I gonna get one. For some reason I never have.

The perfect circle is a nice jig. I have a couple in the shop that I made out of plywood – a smaller on that will do up to 15″ and a big one that does up to 42″.

Made out of AL and I will get some shots of the router hooked up and of it in action.
