I attempted to do some improvements to a Rem SPS Varmint stock. I did it for two reasons. One was to use the stock to learn; the other was to buy some time until I could replace the stock.
I stiffened the stock forend using two broken carbon arrow shafts cut to proper length. I then dremeled out some grooves in the forend to accept the carbon shafts. I also attempted to provide some slots cut strategically in the forend for mechanical lock. Using JB Weld Plastic Bonder, I bedded these arrows into the forend. Pot life of this epoxy is only 15 minutes or so. Gotta work fast. The next day I cleaned up the epoxy. Looked okay and seemed to be holding to the plastic stock.
I then started prepping the stock for bedding to the action. Prepped the area around the recoil lug and made some slots for mechanical lock.
The area that supports the action was prepped by drilling some small holes for epoxy to fill and hopefully provide some mechanical lock.
I wanted to use some pillars, but this SPS stock doesn't have much area around the action screws due to the honeycomb structure for pillar diameter that is very large and would result in pillar walls that would be thinner than I'd prefer. So, no pillars.
After prepping the barreled action and cleaning the stock real well with soap and water chased by isopropyl alcohol, I used Kiwi brand neutral shoe polish for a release agent and put copious amounts of it on the action using a small paint brush and Qtips followed by a soft cloth polishing. Action screws also received a good coat of the polish.
Action holes were filled with clay prior to the Kiwi neutral shoe polish.
I bedded the stock using the same JB Weld Plastic Bonder. Had to work really fast! Very short pot life for this.
After allowing ample time for the epoxy to dry, the action was popped out of the stock.
Looked ok. However, there was on place where the epoxy did not want to stick to the stock. That area is a thin spot near the ejection port. Not much surface area there, and combined with the plastic stock's poor adhesion quality, it didn't stick good at that one location.
Would I do it again? Probably not. At least if I ruined this stock it wasn't a great loss, so I did it. Painted it afterwards so I could at least see something other than black plastic.
