Thought it would interest Iggy and DoN

Neat. But I find myself wondering whether he has removed the
key in the R8 spindle -- since there was no fumbling to rotate the
holder going into the spindle.

And I would like to see the actual interface between the motor
(an impact wrench, I think) and the top of the drawbar. It seemed to
engage a lot more easily than I would have expected with the possibility
of the hex at the top of the drawbar being out of phase with the hex
socket on the impact wrench.

You guys have never seen those before? They have been around in machine
shops for nearly 20 yrs in one brand or another.

But -- I've not been in a professional machine shop in that
period -- at least not where I could watch things in such detail. The
one at work had machines old enough so the closest to CNC was a pure NC
machine -- no built-in computer. And I never saw that one running.

But -- they did have a planer large enough so it would have
carried my Mazda B2600i 3/4 ton pickup truck and planed it down to
nothing -- if it still worked. :-)

Enjoy,
DoN.
