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

Re: Mini-Lathe Gear Reduction

From what I have read, one issue with BLDC motors at low RPM involves "cogging", so it seems a GR would still be very much on the plate. What I am really curious about, though, is this:

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

You have actually completed yours so your figures are likely to be more accurate that mine.? Your prices in pounds Sterling would be around US $180-$240, which is appreciably less than

ELS Costing

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

This is based on

I think one of the problems with the Sieg motors is that the end bell is radiused, not flat. I believe the end bell is some sort of filled nylon.

While it's not absolutely necessary, I feel that gear reduction on the mini-lathe makes it more like, as my friend Barry once described it, "a big boy lathe".? This is especially true
