I am still on the 10.04.4 LTS install, with just enough stuff installed 
from other sources to screw it up.  Last time I looked at Mate, it was 14 
and I liked it.

Now if we just had a 64 bit kernel/distro build for LCNC.

But I am about to buy one of those Bolton 11x28 Lathes, if I can find a 
decent price under $2900, this *&^$ 7x12, no matter how much power and ball 
screws I throw at it, still can't do a decent cut, too much rubber in the 
frame & bed.  Plus I just put a cutoff tool on it to get rid of a mistaken 
too small a cut, touched off x several times and the DRO still lied to me 
by about .150", and this thing has been calibrated to .1 thou in a full 
inch of travel.

But the final blow just now was when I put the cutoff tool in and tried to 
scrape off the 1/2" of too small a cut, and my jackshaft bolted in tight 
enough it might crack the bed casting, shifted and loosened the drive belt 
into the spindle head, totalling a few teeth on the belt.

Its time to stop the bleeding, the Bolton I looked at on ebay a couple days 
back is variable speed drive, an inch and a half spindle bore, and 500 lbs 
of iron.  I can CNC it for not too much more than it took to do this 7x12.  
Longer, bigger z lead screw.

And I can strip the electronics, including the reversible spindle drive, 
and re-use the lot as all these motor are Nema 23's but triple stack 425's.  
They don't take a no without raising hell. 

Can anyone comment of the fit & finish of that Bolton beast?

Cheers, Gene
