Before I try my first bedding job on a recoil lug I thought I'd start small and try bedding a scope base to an action. I used JB Weld because it's cheap and easy, and seems to be used often. I do have Devcon but am saving that for "real" bedding jobs.
This rifle was obtained with the scope base already installed. I removed it and noted on test fitting it that the rear portion of the base had a slight "gap" between the base and the receiver when the front base screws were tightened. So, I thought that I'd bed it, using the front two screws to provide most of the pressure and allowing the JB Weld to fill the gap in the rear.
Release agent applied to the receiver, the mount was cleaned, degreased and prepped, JB applied to the mount and the mount was installed by tightening the front 2 screws until they started to "grab." The rear screw was then tightened until it met resistance and I stopped.
See photos below. I'm a bit stumped that 1) the metal of the base appears to not have ever touched the receiver though "almost" did at the location of the arrow, and 2) some of the JB flaked off despite very thorough preparation (I paint parts I restore for Corvettes so I'm not new to prep work). The JB that did not stick to the scope base easily removed from the receiver using my fingernail.
Should the front two screws have been tightened further to squeeze out more JB Weld? Should I roughen up the scope base further so that the JB adheres better? Or should I not have removed the base from the receiver to check my work?
Thanks for any feedback you may have.
