That sounds like good advice. I did pick up a Forstner bit at Home Depot for $7 which seems reasonable. Now I am going to work on my steady hand skills.NFK - Even a hand drill would be preferable to a Dremel tool as the added weight will provide stability as you cut. I would not attempt it with a Dremel unless you are a talented engraver or such!
A pilot hole will also help to stabilize the bit and preserve the edge of the checkering.
that's right, 33/64", but I could not find one, used 1/2" instead. 1/2" is 1/64" too small but some careful "reaming" with a sanding drum on a dremel and the medallions will drop right in.colt medallions are 33/64ths, at least that's the bit size.
Yes, that's what I've experienced in the past. 10mm will also work for S&W if you can't find 13/32. They are about the same dia.S&W medallions are indeed 13/32.

NFK - sounds like you have S&W medallions. They mount very differently from Colt.
