I have a local machine shop tig weld the hook. I have done a number of them. I have learned to have him put the weld past the sides of the hook otherwise as you take it down the sides will have a bevel. Dr Drew has some pictures of one I did. It takes about two hours to fit. I use a hurricane oil lamp without the glass hood and round files.Mostly you need patience and take your time.

He has not overheated any yet. There is a lot of metal there and not a very big weld.

I hope that helps.

So many guns, so little time!
