well i just removed the end cap on a thomas boswell box lock the cap was threaded but was staked. i ended up using an end mill to remove it.i milled out the center and pulled the threads out. the pin unscrewed.now i have to make a new pin and endcap.i have welded the hook on a lot of guns and blacked the barrels down on face.if done right it is not half assed and less work, less chance of a major screw up.and you had better make sure the pin is removable before starting some as are cast in.you could also piece the hook.good luck mc
