Hello All,
I have been downsizing my shop lately, sold my old decrepit Sheldon
12" lathe because it's too long, and have been on the lookout for a much smaller lathe.I visited a local shop that folded to look at a SB 9" he had for sale. The SB was really worn, but sitting next to it was a 1980 Winchester
10 x 22 made by Shen Wai in Taiwan. It is in really nice shape. It had some upgrades; a newer 1 hp Dayton motor. It had a Cushman 6" 2-jaw chuck with special jaws on it; almost totally useless for my needs. So I said to myself; no biggie, if it's a Cushman chuck, it must have a somewhat standard spindle mount on it right?Wrong, after I bought it & got it home. Removed the chuck and measured the spindle threads. It appears to have a 2" 8tpi spindle. The unthreaded portion measures 2.00 diameter, the threaded portion outside diameter is 1.950 or so. It has a 1" hole through the spindle, tapering up to 1.200 or so. (a #4MT?)
I have never seen or heard of a 2"x 8 tpi spindle. It seems I have two options; turn the spindle down to 1 3/4" x 8 to fit the newer Chinese backing plates & chucks, or special turn a rough backing plate to fit my threads. (which will be hard because I will have to do it on this lathe!) Anyone with suggestions? Oh, and I cannot find backing plate blanks anywhere, looked online at WTT, Enco, MSC, etc. Any suggestions?
THanks, Jeff
