Grizzly CNC update

Finally got the mini mill home and started to strip it down - Just as well, I
have found most of the slideways have quite a bit of grit mixed in with the
grease that covers everything. Once all the various parts have been washed
and cleaned, I'll be measuring up for the ballscrews and motor mounts.
There looks to be plenty of room for the Z and Y screws - The X might be a
bit of a squeeze.
I have been presented with a short length of 32mm dia ballscrew complete with
a nut - Having about 125mm of travel available, I may well look at using it
for the Y axis.

Regards, Paul.
