Hey Andrew,
Pretty hard to go wrong with a Cinci at 500 bucks.
I don't "see" the wear you mention in photo two. What do you think is
worn? It isn't a keyway per se, but rather a "drive" channel. Nothing
fits at all tight into it. I only engages a dog that slides in it all
the time, and used to turn the saddle hand-wheel when you engage the
clutch, so to speak. For thread-cutting, the dog is dis-engaged and
the half-nuts clamp onto the threads of that shaft. I don't see a
thread-dial though, so ask about that.
Why is the compound off? What are the V-belts looped around stuff
for? What power is required to run this (voltage, single phase, amps,
etc)? What is the "tin" guard there for?
No chance of getting a friend with some experience to have a look at
all this? Just be sure that he keeps his hands out of his wallet!!
And what are your plans to get it out of the basement? Maybe offer
him the $500, but that the lathe be FOB his driveway, and to be in the
same good condition as now. Or at least be sure that when you move it
and his house gets damaged, it isn't your problem.
And you may wish to make some sort of a restoration project of this,
but hey...if it was me..... it would be clean it up, lube it up, run
it up, and make chips!!
Take care. Nice Xmas toy.
Happy New Year.
Brian Lawson,
Bothwell, Ontario.
