A nominally 1500 lb Sheldon lathe that is about 65 years old.  The 
compound the toolpost sits on was apparently broken, possibly by falling 
over onto it. That, since the computer makes a compound slide a 
duplication of efforts, has been replaced by several lbs of machined 
cast iron, rendering the toolpost support at least 10x more rigid than 
when it was new. IOW a huge improvement in the overall function. I also 
have a 7x12 that has had the same conversion, and a tapered gib 
conversion I built, and with the 1 hp motor, is now a lathe that can do 
a very good finish that can do its operations much faster and about 10x 
more precise than when it was new many years ago.

Then this ones crossfeed screw was ok, but the nut was a mess, so ball 
screws and nuts were installed. But I am having problems with electrical 
noise getting into things, so I am slowly redoing the grounding into a 
single bolt star ground. But I need to go out and get a couple boxes of 
#10 ring lugs before I can do much more. The garage is insulated and 
heated well, but its 13F with 5" coat of snow on both vehicles. So I'm 
hibernating, like any self-respecting & long retired old bear. :)

It sounds as if it needs to be run before you walk away for the night.
