There was supposed to be more to that post but Mrs.C rushed me out of the house to do errands.
Anyway, I did figure out the overly complicated 'Compound Drive' today. It's basically a dual range transmission with three speeds in each range. Low range is 47, 80, and 130 rpm. High range is 220, 370, and 600 rpm. I'm going to make a sign for the wall stating such.
Right now, however, the speeds are currently zero. The Chicago Die Cast drive pulley on the motor split in half.
Scared the crap outta me, too. I don't know if the belt was too tight, the pulleys were out of line, or there was a flaw in the casting. I'll head to Ace tomorrow with my $5 off coupon and get a new one. I do know that when the outside flange of the pulley parted company, the lathe ran quiet and stopped shaking. Before all that happened, though, I did manage to check end play and run out on the main shaft with my cheap a$$ dial indicator. Run out was .008mm and less than .005mm for end play. Not too shabby.
The 4 jaw chuck is giving me flashbacks of Freshman Machine Shop fifty plus years ago. That's gonna take some practice.
