Hi All
Well I finally got the the 6” Shars zero adjust chuck mounted and adjusted. I am really suprized with it. I have it down to .0002 TIR with .0008 repeatabily on ground drill rod 6” from the chuck. I used my 2” Sterrett .0001 dial indicator with my Noga large base which is rock solid. I could hardly believe it. My old Bernhardt 6” has .007” TIR with that same drill rod. I also have a 4 jaw self centering scroll chuck that I was able to get down 2-3 TIR. I turned the adjuster stub on the backing plate -.005” smaller than the d1 chuck dia. to allow 2.5 thou. adjustment. They spec it at .0002 but I figured 1-2 thou. boy was I wrong. I plan to get another Shars as money allows. That’s great for a hobby lathe. I have the lathe leveled side to side and front to back with my Sterrett Preston level. I can’t believe how much fun it is to have to not fight them old chucks. Will post some picks when it warms up a bit.
