I probably need to reface my table too, its managed to collect a dig or 3 from 
errant end mills.  But first take up all the slack in the jibs, else it will 
sag from its weight on the far end, and cut the end under the bit a thou or 
so too much.

I put some more links to pix up on my web page.  Gotta make up some 
explanatory text one of these days to wrap around the pix.  Its not running 
yet, waiting on a couple of bags of enclosed connectors, I'm going to switch 
the whole lashup away from those molex's before I get a piece of swarf in 
them and short out the driver board.  Tain't purty, or cheap, did that 
once. :(

The Ampmeter says its 15 volt, but it is actually 1.5 amps full scale, and is 
currently clipped into the ac fuse circuit so I can see how hard the spindle 
is working.  It gets wired in solid, and solidly mounted beside the spindle 
motor one of these days (or nights as the case may be)

I wish that $500 (6 years ago) Olympus camera of mine had a viewfinder that 
corresponded to the image it takes, neither the zoom nor the field of view 
follow the zoom of the lens at all well.  Zoomed all the way in it appears I 
get less than what I see in the finder, whereas zoomed all the way out, I get 
more than I see, a lot more.  The moral is to shoot wide, and crop with the 
Gimp I guess, it already did wonders for the gamma, or the dark stuff would 
be almost invisible in these shots.  It has a live color lcd viewfinder too, 
but if I turn it on full time, battery life is 10 minutes max. 

Figuratively speaking, I think George is actually making progress faster than 
I am.  He already knows the basics of the machinery, something I'm learning 
as I go.
