Jig for edge shaping circles on Router Table?

Hey Chip
Simple but effective. Thanks for sharing.

Thanks, Jim. I’m going to make this and play around with different designs. I’m thinking a wider angle wedge would be better. I just happen to see a picture of this somewhere. I intend to use this on the project I emailed you about.

That jig looks fine Chip. Now the dumb questions. I am guessing you want to use this because you don’t have a bearing steered bit with the profile you want? Or are you looking for feeding stability? I am hoping to learn something here.

-- Mike, American in Norway

Feed stability, definitely. I’m still undecided about which profile I want.

-- Chip, Massachusetts

I’d guess that the angle width would depend on the size of the circle, no?
I’m wondering too, about how to gauge where within the cut out circle to set the bit?
If I use a bearing guided bit with the fence, I can simply bury the bearing. Or bring it even with the fence face. Can’t do that with this jig….or, am I missing sumpin;?

I don’t think you’re missing anything, Gene. I guess everyone has different tools, but my limited tool selection leads me to believe this may be the best jig for the project I’m working on. I’m new with a router, so I may find this is junk and have to think of something better. But right now, it seems perfect.

seems like a great idea to me ,
the larger the circle ,
the further back the holder ,
till the circle touches the bit .
this is a good way to stop the part from spinning freely !

kind of like a starter pin .
