According to the Instructable author, the lathe had been run into by a
forklift and was badly bent.
As far as the animal is concerned, that's a topic for people other than
me on a list other than this one.

I do wonder if that will damage the variator. I guess I could ask Allspeeds.

Ah, yes. I should have thought to look there. It suggests that a 3hp
lathe is a bit marginal for a size A and I should look at Size B...
I need to take some measurements.

My new lathe will need a new toolpost (it doesn't have one).
I have used the "Dickson" style in the past, but I am wondering if a
Multifix clone might be worth the extra cost.
I don't really trust Dickson-type ones to index properly, as it seems
to be something of a lottery which of the 4 flats e

Did you notice the rental generator to make the power to power the lathe?

I guess that if you're worried about the torque at low speeds I would keep
