Re: [CAD_CAM_EDM_DRO] turning loooonnnnng skinny tapers.

Yes, the three cylinders are connected in parallel.

I don't know what kind of force problems would develop here as I got the
information from a guy in California. He said the system works real well.
You do bring up an interesting point though. Next time I need to turn a
long taper, I'm going to give it a try. Maybe even test with some heavy
cuts to see what would happen. I strongly suspect it wouldn't be much of a
practical concern.

I wouldn't worry much about wear on the bearings...unless one of them fell
apart in use. Small bearings used for the purpose are pretty cheap and
easily replaced.
