My dad is getting up in the years and is cleaning out some of his
unused/nolonger used tools. He gave me a 8" 4 jaw chuck that was made in
Germany. It has never been used and will need a backing plate. It is a 4 jaw
with self centering jaws, I have not come across any of these in my travels.
It must work well with square stock and would work just as good as a 3 jaw
on round stock, any other things I am mising?
