Hi,
I have won a 4" Pratt Burnerd True grip Chuck on ebay, there are 3 adjustment screws that bear against the internal parts of the back plate. What is the correct procedure for truing the chuck for a particular diameter stoc? Do the back plate screws need to be loose or sung or tight while I am turning the adjustment screws?
Many thatnks and regards,
A.G
