Tom,
I have a similar lathe and when it was new I went through many belts
until a guy in Ireland suggested that I work the edges of the movable
pulleys with a file and fine emery cloth. I had just bought five belts
from a motor parts supplier as they were a lot cheaper than from the
lathe manufacturer. After doing as he suggested I fitted one and it is
still going five years later! In fact I have misplaced the other spare
belts so I hope this one goes on forever. The other suggestions re
lubrication are also essential.

Ok, I know it may not have been the smartest thing, but I have a central
machines (harbor freights) 3/4 hp lathe. I've enjoyed learning on it, but
now I have a little trouble, or at least I hope it's little. My lathe won't
run on the higher speeds. The lathe uses a lever to change speeds, and when
I try fast speeds, lever won't go and the belt stops turning. Can I solve
this trouble by getting a new belt? If so, I might have a new problem. My
wife bought me the lathe, and I have no documentation with it. I might be
able to figure out the size, but I'm not sure how to take it off or replace
it. If anyone could give me advice, I'd appreciate it. Thanks,

Tom
