I am starting to fab steve bednior's (sp) ball cutter My 4" chuck wo't take the 3" round steel stock I aquired for the body of the ball cutter, so I bought a used 6" independant chuck but the key required is an Odd ball not metric, mind you but seems to be a tapered broach in the adj. screws. the chuck key shaft that I have needs to be narrower for an inch or so because the jaw interferes with the key as the jaw extends out of the chuck... :-\
Thats the set-up story... Now...... I put the chuck key into my lathe to turn the handle down to fix the problem BUT.......
usinga tool with carbide cutting tip it's all I can do to scratch the key handle ???
I assumed the key is tool steel and I expected it to be hard....But this steel is " INDESTRUCTABLE" is this normal ??? if so how do you cut tool steel if one needed to cut or drill a piece ( I may want to cut a collar from another old chuck to use on my Emco which uses a plain back chuck mounted to a face plate that mates to my spindle with three bolts.
Sorry for the long post :-[
thanks
