Re: Mill/Drill Ballscrew dia.?

It' a Jet-18-MD if you take a look at
Enco's, Ro-Fu, Harbor fright they are all
made from a strikingly similar casting.
Pricewise The Mc-Masters-Carr rolled Ballscrews
for 5/8-0.2 and 1.-0.25 including Nuts are very
close, maybe a few Bucks more.
I have just received some info stating that
the 5/8 screw would be the biggest I could
fit in there.
Anybody able to do better?
