Does it ever end?
I finally found some 5Cs that I thought were a decent deal, they came in today. So, I got out the Royal lever collet closer that I stored away right after I got the lathe. Oops! Since I had no immediate need for it, I forgot to clean it up!
So, I get started with a dismantle and clean.
Oops, the bracket for the swing arm mounted to the head stock is busted. No biggie, I'll just mill a new one out of Aluminum.
Oops, looks like the draw bar threads are well less than 50%. So bad that it's a bit hard to start a collet, and even with it almost bottomed, it's still got enough wiggle to worry me. Hmmm, maybe it will work for HSM duties, but I guess I need to look into making a new tube...
Oops again! The main mechanism is not obvious in it's disassembly.
The rear most knurled ring (to spin and tighten collet) behind the collar has a set screw and appears threaded. But it's been whacked and the threads are a bit messed up. I'll probably have to chuck it up and face off a bit (or just cut a small "V" at the threads) to remove the first damaged thread. Then the main collar on the collet side of the mechanism, the one that fits over the splined spindle adapter, has a flat head counter sunk bolt. Taking that out does not seem to free up anything. Probably just crud holding it locked. Oh, and the main bearing was seized, apparently causing it to spin on the center race? There is an grub set screw on what appears to be a collar that holds the bearing on the inner cone sleeve. Is that collar threaded? I can't get it to move, and there seems no way to hold it (the cone sleeve) if it unscrews.
<sigh>
So, anyone got a parts diagram on one of these things before I break something? At this point, I figure I'll probably making or buying one of those hand wheel closers...
