I'm thinking of buying a bench gun with a glued action and would like to change calibers. So my question is, how do you go about rebarreling a glued action? Also how do you actually glue in the action? This would be my first glued action gun so I'm curious. Thanks
 
1st I would get a copy of the drawing for that particular action from the manufacturer. It will show you the tenon length, tpi, cone angle & headspace dimension. Hopefully the threads on the original barrel fit properly. Turn the tenon to proper dimensions. Chamber to proper depth checking with the proper headspace gauge & then cut cone angle. Using thread wires or triangles, chase the treads to the same pitch diameter as the original barrel.
 
I guess I forgot to add it's a blue printed remington 700 short action.
 
Assuming the present barrel is correct, remove and copy it...
 
I would remove the action from the stock and pillar bed it. Then you can use the action as your thread gauge.

If you decide to stay with the glue in then you have to duplicate the tenon EXACTLY before removing the bbl from the lathe. Then you just screw the new bbl into the action and tighten it up with an internal action wrench and a bbl vise. If you opps too big then you get to put the bbl back in the lathe and pick up the thread and cut it a bit smaller.
 
What is usually used to glue in actions and how hard are they to remove?
 
Most use a two part mix glue, JB Weld is pretty popular. On actions that are a close fit in the stock, I just skip the bedding and do it all in one step.

Most epoxie glues will "let loose" with about 350 degrees of heat. A popular method of applying the heat is to remove all the scope rings and bases, and lay a iron on the action at full heat. The heat will conduct into the metal, and a swift pop up on the barrel will generally break the bond.

You can also use a air heat gun, but it is difficuly to avoid hurting the finish on the stock..........jackie
 
That's what I wanted to know. Thanks very much Mr. Schmidt. Alan
