I will use my acetylene torch. Chuck, you mention the ribs "falling off", so I assume you hold them in a vise by the breech end and heat the rib on the underside of the barrels until it comes off, them turn them over and do the same thing on the other side? You must have to heat the entire length of the rib evenly so that it comes off kinda all at once.

vh20, thanks for the reminder on the witness mark. It'd be a bummer to do a nice job on this and the barrels be out of regulation.
