No, ya got lost somewhere Dan. The question at this point is how do you
resize a forstner bit by dressing it, and how could it possibly be the
ideal bit to resize.

Turn down the outside, or grind down the outside. It is a relatively
small
height, and all solid, except for one or two small areas.

Thanks Geoff, that is the question on my mind too. If you could even find
one that was 11/16, you would have to pull .030 per side off of it to get an
oversized 5/8. If not, you would have to pull .060 per side off of a 3/4. I
don't see how you could do it without a tool grinder.



If you own a bench grinder, drill press or dremel equivalent make a
bracket out of sheet metal, phenolic or hardwood to hold the tool. It
sounds a tad Rube Goldburgish but it can be done. I made a few for
grinding lathe tools.

In the case of a rotating bit you need symmetry as much as size. It
seems to me you coulduse a wood block drilled to accept the tool shaft
at one end and drilled to make a pivot point at the other. A simple stop
like a machine screw could serve as an adjustable stop.

Visit a machine shop some time, you'll see some rather clever widgets
made for a one time use. You never know, they might have exactly what
you are looking for.
