Slight variation
I'm working on a variation, kinda a hybrid of this method, or a combination of ideas from that thread, one step at a time, then testing each change......
Pillar bed as Cnrtyboy stated, then added a perch out of aluminum 1/8" plate above the pillar about 3/4"X1", and filed the receiver surface flat to mate to it. The plate is bedded in by dremeling out this section to get the right height, then epoxy-ing it into permanent position, and using a nut on the takedown bolt, is held tightened together for 24 hours. Then, I looked at the crossbolt method, and decided to try cross-bolting only the rear pin hole, with slight downward pressure, but use a Kidd pin in the front receiver pin hole. This triangulates the pressure points both front and rear while stabilizing side to side at the same time. I have no idea if it is any better or not, haven't tested it yet with the crossbolt in place, but I think it will be every bit as successful, and a much easier installation. The Kidd pin holds my group up with tighter tolerances to the bolt, and stabilizes the front of the group while helping the action to be more consistent by the bolt/firing pin striking better/more consistently. After testing that change, it'll be onto bedding the front of the barrel as per Countryboy in that post, and removing the pad up front, all in a one step fashion with testing between each change, and good notes, so I can document what's happening. :t When Ted says its better than Glass bedding, I listen. :t
I got enough threaded crossbolts and countersink washers to do ten like this if anybody wants a set-up to try and avoid exhorbitant shipping costs on a small order. :t I picked out stuff that allows for a flush mount of the countersunk crossbolt screws, kinda a larger version of the Kidd pin set-up. :t
You can use either black or stainless machine screws to match whatever you're building. :t
