I covered the barre/receiver junction with tape and a liberal coating of car wax to prevent the JB weld from sticking to it
I mixed up the JB weld and put some under the washer and on top, when the barreled action is clamped it, the excess with squish out and the flanged washer and escutcheon will touch each other, preventing any movement.
The next day I pulled the the gun apart, there was a few small pieces of tape stuck to the JB weld, but otherwise everything is peachy. The fit is perfect, no rocking fore and aft and it feels rock solid.
I had planned on using the 10-24 x 2.25" long button head stainless screws to anchor the receiver.
The screws will go through the rear trigger pin hole which is 3/16".
3/16" is equal to .1875", a #10 cap screw is .190, slightly larger, which will fit, but will be tight.
So how do I drill the stock and get the holes lined up perfectly? I found a post on the Rimfire Central forum by Hipshot, he built a jig using a piece of angled aluminum and long 6-48 bolts, screwed into the scope rail holes.
I bought some #6-48 screws that are 1/2" long, which should be plenty long enough.
I couldn't find a piece of 90 degree angled aluminum, so I made one. The metal is from the same sheet I plan on using for the side panels.
I marked and drilled the top holes with a 9/64" drill bit, then drilled the side trigger pin holes with a 3/16" drill bit
A trial fit with the #10 cap screw
Then again with the trigger group installed. I drilled the front trigger holes as well, but I don't think I will be using them.
