Has anyone tried ball end mills?
They come already ground with the radius on it just like your talking about bob. The only problem is that are expensive, but not much more than a router bit would cost, or buying a dremel - mine met it's maker many moons ago
- and the bits.
I've never used them on wood, but i don't think you would have any problems with softer woods like cedar. They might burn out, but if you can't get the angle right by hand - which is difficult, but possible - this may be a good way to go.
I don't know any stores you can them at. If you know anyone who works in any 'craftsman' type trade they can get it through MSC. Or try Ebay or any search engine for 'ball end mills'. Don't buy one too long, you wont need more than 3/4"
