I made some headless bedding screws from some long screws I got from Lowe's and ground the heads off. I wrap them in several wraps of electrical tape to help keep them centered in the stock, then slather them with Kiwi neutral shoe polish. Haven't had one not come out easy yet. If the Kiwi doesn't keep them from sticking the electrical tape will, you can easily turn the screw out from the tape itself. I also use electrical tape instead of surgical tubing to hold the action in the stock while curing, several tight wraps of e-tape around the front and rear bridge hold it in place great and it's a lot easier than dealing with that surgical tubing, plus a roll is really cheap at the dollar store. I use Marine Tex grey, never had a problem getting it to flow, the consistency is just right for me.
