   Well, at least you didn't say "Alan Jeffrey"...when my bride uses my middle name it usually means that I've got some 'splainin' to do, as Ricki Ricardo used to say to Lucy.

   Greg, I had previously posted my proceedure on the thread below, but I've copied it here also. Take care.  -Al

I lap the ring bottoms with a lapping bar and scuff the lapped surface up with some 80 gr. aluminum oxide paper to hold the compound a bit better. Then, I chamfer the parting line between the flange and the bottom half of the scope tube 'cradle' to about 45 degrees. This helps keep the ring from pinching the tube. I repeat the chamfering on the top ring half for the same reason. Next, I degrease the cradle with acetone and apply release agent to everything but the bottom ring cradle (including the top ring halves). Apply release agent to the scope tube where it will set in the rings.

   For a compound, I've used lots of epoxies with success. I prefer the AcraGlass Gel, though. It has a substantial amount of Nylon used as a filler and it seems to offer the the slightest bit of flexibility. However, I've used ProBed 2000 and JB Weld (both the original and the JB Quick varieties) and really can't say that one is better than the others. Basically, any epoxy that has limited shrinkage should work. I stay away from stuff like Steel Bed, as it's high steel content can allow rusting.

   Apply the compound to the ring cradle, set the scope in the rings, and keep the scope in place by wrapping masking tape around the tube and stock or by using a couple of tourniquets. You want the scope tube to be down snug against the rings, but not smashed tight...like bedding an action, you don't want to be stressing anything at this point. Make sure the scope doesn't want to roll to the side as the compound dries.

   After the compound dries, pop the scope out of the rings, clean up the excess compound and chamfer all edges with a scalpel, X-Acto knife, or a piece of 220 grit paper.

   I'll put the scope back in the rings and snug the tops up and let it sit for 2-3 days and repeat the process on the ring tops, depending on the situation and fit. Scope tubes will vary .002-.003, so I've been not bedding the top halves lately to allow better clamping of different scopes.

    Bedding rings this way, you can swap scopes and be assured that contact will be good and that your scopes won't get scratched.

   Greg, this is so easy that even a German-Norweigan dirt clod like me Blockhead can do it!  -Al
