i did this to a featherweight.
the "1/16th to 1/8th inch" is closer to 1/4in. i didn't do it, I like your JB weld idea.
and more than likely your action screws will be too short. a trip up to ACE hardware can solve this.
not sure of your caliber, but to shim the mag, i used the large home depot paint stirrers. a piece on the other 3 sides snugged up pretty good.
