A local acquaintance recently bought a TC White Mountain Carbine from another acquaintance of both of us. The White Mountain Carbine was wearing a front mounted scope base for a long eye relief scope. I was asked if I could take the base off and put the original sights that came with the gun back on. Of course was my answer. However those base screws would not budge even after applying a torch to the screw heads for a period of time long enough to cause any Loctite to let go. I called the original owner of the gun and asked him what he used to secure the screws so tight. His answer was JB Weld on the threads before he tightened them down. Yew boy! So much for saving the base. I drilled the heads off of the screws and got the base off but that left me with a very short portion of screw extending above the barrel and it was barely enough to get my vise grips on. I applied heat once more putting the the tip of the blue flame on the screw stub sticking out of the barrel. Once the screw started to turn red I snapped the vice grips back on it and turned it out, then repeated on the other 2 screws. I spent 2 hours doing a job that should have taken 10 minutes
The guy that welded the screws in the gun also has 3 Marlin lever guns for sale and they are all wearing scopes. Same dude is thinking about buying all three of them and wants me to take the scopes off and reinstall the sights. Yes JB Weld is involved with each one of the three. I told him to offer the guy $50 less for each gun as If I am going to spend most of the day on the three I should be paid $50 each......he acted like I was robbing him at the price of $50 ea. so I withdrew my offer to get involved. He did not make his million in private business by not charging people for their time.
Bottom line.....don't use JB Weld or epoxies to keep base screws tight!
