You are probably better off without that lathe. It's a LeBlond Heavy Duty, somewhere between 1930 to 1950 vintage.
The thing that caught my eye in your previous post was the comment that you turned the compond dial several times with a consistant 100 graduations backlash.
1. Probably the dial you were watching had 200 or 250 graduations in one revolution. If you found 100 grads of revolution on a 200 grad dial; it means the screw/nut is one-half worn out. New, this lathe probably had only 4 grads or .004 inch backlash.
2. Typically, the compound screw gets far less use (and therefore wear) than does the crossfeed screw. .100 inch backlash in the crossfeed screw/nut doesn't surprise me on a lathe this old, but that much backlash in the compound screw/nut indicates a lot of use!
