That should be possible. I am thinking of parafin (sp?). That is a lot
different. Worth a try.

Not able to recycle. Might even cause global warming. All my technic has
chaulk dust and bread crumbs imbedded in it. The wax can always be run into
the chip auger, up the elevator and into the chip recovery system.

I am guessing that your building a vertical mill. This is a vertical Z axis.
You referred to an A axis which goes with the vertical configuration. I wish
I had a picture of the tool changer used by Sundstrand on their vertical. It
was pretty simple. I will hunt the internet to see if I can find something
like it.
