Re: Mini-Lathe Gear Reduction #GR #3D #CNC
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

Fast Eddie, this is forum for such discussions!! In fact that is the reason it was setup! Or at least that is my understanding. Ralph

Re: Mini-Lathe Gear Reduction #GR #3D #CNC
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: (and this may

Re: Mini-Lathe Gear Reduction #GR #3D #CNC
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

Re: Mini-Lathe Gear Reduction #GR #3D #CNC
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 +

Re: ELS Costing #RELS
Hi, Richard, 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 #RELS
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

Re: Mini-Lathe Gear Reduction #GR #3D #CNC
Hi, Fast Eddie, Many thanks for the explanations and the photos.? I have personally never seen the end bell of the Sieg motor, and this clarifies a number of things for me. If I interpret the

Re: Mini-Lathe Gear Reduction #GR #3D #CNC
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. A similarly designed plate that attaches to the end

Mini-Lathe Gear Reduction #GR #3D #CNC
Hello, All, 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
