Boyd's stock for Ruger American

Hey SWO1, my stock came in from Boyd's yesterday. Here are the pics of stock with the "V" blocks that needs bedding. Not actually pillars, they don't go into action screw holes but sit on top. I dry fitted the rifle to stock, everything lines up good. The only problem I'm having is with the detachable magazine. Dang thing is so tight when I attach it, I can't remove it without tearing the rifle down. Going to get the dremel and sand some where the magazine goes and try to loosen it up a bit. I bought the slow setting JB weld and some Johnson paste wax as a releasing agent. I'm not sure of how much JB weld I need to use to bed. Do I need to be skimpy with it? Or do I need to be generous with it to make sure I get a good bond?
