I am trying to remove the liner without damage to reuse then reline and rechamber to the original calibre.
The liner has been soldered in and all efforts to remove have failed.
I counter bored each end to get rid of any peening, put a SS rod through the bore with a button on the muzzle end and a rong on the breech end to fasten to the back of my skidsteer.
A pipe with a collar fitting the shoulder at the breech end surrounds the barrel with holes for heating and the muzzle end attatched to a chain block.
I have heated the whole barrel with a torch untill nearly red. The solder runs out. The chain block nearly lifts the skid steer but the liner wont move.
I have looked for mechanical fastenings but cant see any.
Any ideas.?
I may just have to drill after all.
