[Fot] TR4A Stripped Threads in Block

[Bob Kramer]

I had one block were a previous owner must have done the same thing, I 
couldn't get two studs to turn. The one in the front was easy, I could see 
that a hole had been drilled and tapped from the side of the block an I was 
able to get the set screw out after much effort. The long stud was harder to 
identify and I finally figured out that the guy had drilled through the stud 
hole into the bottom end and tapped that hole to match a threaded hole he 
created in the long stud. After all that I junked the block because I have 
spares, but if this is a restoration this technique would probably save the 
block. Truth be told, if I just knew about the locked down studs before I 
manhandled them trying to get them out I probably could have easy-outed the 
set screws, or just left them alone.
