[John Sabato]

Gerben, If you decide to do this on your own, considering that the barrel to be removed can be "sacrificed" since it is unusable, you can put the barrel in a lathe and very carefully relieve the shoulder of the barrel that touches the receiver...being careful not to remove any metal from the receiver. This will relieve much of the stress holding in the barrel.

You can also use acraglas in the vise blocks and glue the disposable wooden blocks directly to the barrel being removed instead of using release agent. This will prevent barrel slippage during the removal process.

Design your receiver wrench carefully to prevent denting or scratching the receiver...

Good Luck my friend and let us know what you decide and how it turns out.
