My Delta Bandsaw is from 1939. I power it up, cut a piece of wood and turn it

newest OS or Computer hardware.
Well, yes, and that is part of why my Sheldon lathe has not
been CNC'd yet. it is a FINE manual lathe, and I'd hate to
overcomplicate it with a CNC retrofit. Most of the jobs I
do on it are WAY too simple to need CNC. (On the other
hand, I do some manual machining on my Bridgeport mill,
using LinuxCNC, and that is all fine. Jog dials and jog
keys.) But, metric threads and tapers would be possible
with CNC, which would be the real point of a CNC conversion.
I do much more complicated things on my mill, and CNC has
been a GODSEND on that. I used to make complicated panels
with many slots and cutouts, and these were always
high-tension jobs, were one momentary slip of attention
would ruin the whole part. Now, I can view the preview
window in Axis and be pretty sure I'll get what I want first
time! In the VERY rare case where it doesn't, I can go in,
fix the wrong number and press a button to do it over.
