I have a VZ24 barreled action that has a sewer pipe bore so I want the barrel off. I made some aluminum barrel blocks/bushings for my barrel vise to fit the barrel, sprinkled rosin on the mating surfaces and clamped it in the vise. The vise is something I made using 2 pieces of 1" steel plate and 7/8" bolts so fairly heavy duty. I am using a receiver wrench that came from Midway that I added another handle to so now it is like a very large tap wrench. I'm using a large breaker bar to tighten the bolts on the vise to the point that I am afraid I am going to break the breaker bar - I am a large guy 260 pounds give or take few pounds so the vise is clamped tight but yet when I attempt to turn the receiver off, the barrel slowly spins in the vise. I have tried warming the receiver, added Kroil, warmed the barrel, chilled the barrel with ice, got help from a neighbor kid for more muscle on the wrench and even set up a hydraulic jack to push on one end of the receiver wrench to the point the added handle to the wrench begins to bend which is 3/4" hot rolled rod. I left it jacked like that for two days figuring that whatever was holding the barrel in place would just give up. But no, it didn't budge. So I warmed the receiver with the jack pressure still on it but no joy. Next I took it out of the barrel vise and welded the barrel to my welding table. The welds pop off the barrel when I try to twist the receiver off so I figure the barrel needed a bit of warmth before welding being something other than mild steel so I give it some preheat with the o2/propane rosebud. Same thing, the welds let go and take parts of the barrel with them. I am trying to avoid cutting the barrel off and putting the receiver in the lathe and boring barrel stub out but I am beginning to think that is what I will end up doing unless of course, somebody here tells me what I am doing wrong and provides the answer! Thanks for your support!
