I found all the necessary parts for my Super Mauser project. Numrich had the correct stock for it too so I’m on my way to finishing it. Yippee!
But I evidently goofed in doing the Glass bedding. I cannot get the wood stock loose from the receiver & barrel. I did use 2 layers of release agent on all the exposed steel, and yet it will not separate. Bob sez to put it in a deep freezer and it might break loose when it is extremely cold. Has anybody else made this mistake and did the deep freeze trick to good result? The wood stock was very expensive and I really don’t want to cut it off and start over again. What do you guys think?
Yes, I have had to freeze one to get it loose. Put it in for a couple hours, pull it out, give it a sharp whack, should release. If not, put it in overnight and try it again, this is what I had to do. Hope this helps you out. Bill
Answer
Same thing happened to me on a Ruger 10/22. I left it overnight and simply whacked the barrel with a wooden mallet and it popped right off. The wood and metal expand and contract at different rates so the two parts are forced apart by the temperature change. Learned to be neater with the Acraglass. 🙂

Answer
Try the deep freeze like the other say. Give the barrel a good wrap with a non marring mallet. Did the bottom metal come out of the stock? Did you glass bed the full length of the action and barrel? Full length bed just the action? Did you fill all the crevices with play dough or something similar to prevent the glue flowing into them and locking the action into the wood?
Now do what you want and use what you want but I would advise you to throw away the paint on release agents and use the spray on aerosol stuff Brownell sells it really works well.
You may want to take the glass bedding class the next time we offer it, there are a couple of tricks in there. Ken
Answer
I worked in Fiberglass for 5 plus years. You can use anything that will not attach to the glass like wax & oil, or spray on cooking oil should work. Before using it, test it on something like wood. Coat the item and put on the glass so you can see how it works first. If you have air, use about 90 psi– put it between the parts (Receiver & Stock). In the fiberglass industry, this is known to work. As you use the air, hit it with a rubber hammer. Should break loose..!
When I made Boat we would use wax, wax the molds 10 times before making a part.
Also you need to fill in any places (like Ken Brooks stated) that the glass can get into. That may hold the two parts together (like a hook or angle that will hold on to it) . Vaseline also works well. TC
Question Follow Up
Thanks everybody for the advice. The release agent I used must be weak or else I did not put enough on the steel. I had the thought that as I press the steel into the glass bedding that perhaps some of the release agent was plowed aside and the steel found its’ way directly to the wood. I bedded only the receiver top half. The lower trigger plate and Magazine box unscrewed and lifted out perfectly. I only bedded the first 2 inches of the barrel with plenty of release agent.
I’ve got it chilling in a deep chest freezer now for a couple of days. I’ll beat on it tomorrow or the next day. I did a Springfield .30-300 rifle 2 years back and the bedding worked out perfect. I thought I did exactly the same thing. I’ll find my mistake soon enough.
Thanks everybody and thanks Ken!
