Hi, guys, I agree, this is exactly the kind of thing this site is about! I think that I would 3D model and then print it, too.? While I think some of the plastic parts would be adequate for the ELS

Hi, Ralph, I realize that there would have to be gear reduction to at least a 2500 RPM spindle speed (assuming the desire to duplicate the original mini-lathe speed), but what I was speculating about

Thanks Charlie, that is what I was thinking, that you had just not removed them. I would be in the Brushless DC motor camp. But there still would be gear reduction, certainly do not need 4,000 + rpm.

The subject of the cost of the ELS system came up before I joined and was indicated at $400 - $800. Just for interest my feeling is that the cost in the UK is more like ?150 - ?200. This is based on
