Got an hour to play on the lathe today and adjusted the forward clutch. This time, instead of minimal drive I have too much drive 
I'll have to keep trying until I get it right!
The brake clutch is the one that confuses me and that is one that I need to get correct, as I think that this not engaging properly may be the reason why the chuck spins when the control lever is in the off position. When I first got the lathe, you could stop the chuck from turning with almost no pressure at all. Perhaps I should start with this one first.
Whilst it was running, I also played a bit more with the feed/threading levers and the more I do the more I think something has worked its way loose in the feedbox. If I grab the feedshaft and wiggle it, I can get the lever that wouldn't engage in two positions to finally do so.
The leadscrew can now be stopped by hand, which it couldn't before. I'm really going to have to study the exploded diagrams that I have. Its not going to be an easy job but I am confident that I can get it sorted out once I can remove the feedbox. Before I do that I am going to get the clutches sorted out.
I also managed to remove the faceplate from the custom fixture that had been bolted to it. I must admit that I haven't seen a faceplate this size that didn't have t-slots in it.
EDIT: Managed to slip out quickly and have another go at the brake and forward clutches. Turned on the power and the chuck was stationary, so I was off to a good start. Next I slipped the lathe into forward and I got the short wind up to speed, which the manual describes. So far so good. Then I pushed the lever back into the off position and the brake bit in suddenly and hard. 333 rpm to 0 in less than a second! I guess I will have to back that off a bit. The problem is that once I get the spot just right, the teeth on the two wheels that the locking ring engages never line up, so there is always some error in setting the ring. Oh well, I'll get there...
