I want to round over the edge of a 1/2" thick piece with a Bullnose type bit. I figure that it'll produce a nice even rounding of the edge. However the piece is not straight. It has "s" curves and 180 degree turns that make it impossible to use a table fence. At least I think so. What's the best way to successfully round over the edge of my project piece? I'd like to use the Bull nose bit but if there's a different method I'm open to suggestions.

Thanks in advance.

HI Wildhorse

How about a cove bit with a bearing on it ..

Bob is correct (as usual). Use a bearing with the correct offset that you need. The router will follow the wood. No corners- you would need to use some hand tools for the close spaces. -Derek

I can't see why a bullnose cutter in a small based router couldn't be used, if the inside curve is too tight just approach from the rear, just make sure that the cutter is dead on centre of the thickness and you shouldn't see the crossover points. A piece of scrap needs to be screwed to the router base to be kept tight against the rear of the workpiece and remember that with a bullnose cutter you can't lift the router, it must be slid back to the end.
You could of course use the same method using a roundover cutter adjusting it accurately on a test piece and the router can of course be lifted.

Thanks for the responce. However, a cove bit would cut the exact opposite profile I'm looking for. I could use a roundover bit and flip the piece but that can result in the profile being off center.

Hi Wildhorse

Sorry I did say cove but I meant bull nose with a bearing..

Thanks again for the quick response. Just wondering where I can get a bull nose bit with a bearing. I have 2 bull nose bits with 1/2" shafts and neither have a bearing or a place for one. Is there a device like a mandrel that will accomodate a bull nose insert with space for a bearing? If so where can I get one?

You could also use a template guide bushing with your current bull nose bit.

Thanks to both Charles and Bob. Of course my wife is going to leave me if I buy one more router bit. Hey, maybe if I finally made something for her...do ya think? Guess we're gonna find out. I'm going to give both methods a try.

It's exactly for this reason that I joined this forum. Expert suggestions/help freely given. SUPER!!!
