I purchased a nice made in USA 8" 6 Jaw set-true chuck cheap at HGR but it had no back plate. I found a D1-6 back plate on ebay for set-true chuck. But it's not made for the chuck I have. Actually I can't see why 6 jaw chucks are any good for anything except precision round stock and that is iffy too. But I don't have one so I can add to my collection being I have every chuck size and type to fit 4 of my lathes with D1-6 spindles.
I plan to machine the back-plate to fit. Mounting holes in the chuck are 3/8 X 16. What size holes should I bore to provide clearance for set-true adjustment. Further more what clearance should I make on the projection into the chuck that the 4 adjusting screws engage?
I lied about having only one 6 jaw chuck, I have another 5" threaded back 6 jaw chuck that I threaded a shaft to fit and chuck in in a 10" 3 jaw chuck. An old Cushman with 2 sets of jaws and an additional odd set that is wider and softer on the top though the scroll teeth are very hard. This chuck a 2 piece jaws so I van make soft top jaws and my interest in having the larger 6 jaws chuck.
