Please provide your tolerances as I believe that you are a trusted source.

I didn't check it, but the tolerance are suppose to be 0.013 in each side. Total, 0.026 inches.
That isn't easy to ajust and get it running using UHMW sheet like I'm using.
Next time that I take it apart I can check it out.

How much will that rotor piece expand when it gets hot, I wonder?


Here's what a gap of 0.013 inch looks like:

I am trying to make your pic approximately 1:1 scale on my 24-inch 16:10 monitor.

I tweaked the image to 400 x 264 and at least on my monitor it looks roughly right.   Now we are talking about one big rotor fitting into one big donut.  With thermal expansion and the imperfect balancing, and the fact that as it spins up it may go through some mechanical resonance peaks.....  The stated gap looks like another tall tale.

I looked at some clips and I didn't see anything to precisely tweak the positions of the bearings and axle but I look with an untrained eye.

Nice job. It still displays a little bit large on my monitor, perhaps 10 percent, judged by holding the actual caliper up against your screen image.

Yes, it appears that the rotor shaft bearing blocks are mounted with a triangular bolt hole pattern to the material of the main side frames. How is it possible to have enough clearance in the holes for the bolts to go through, but still not have so much slop that the alleged tight rotor clearance can be accurately adjusted and maintained? How can mere bolts through a soft material maintain a secure mounting through the vibration that the device evidently experiences?

At that spacing, even the issue of whether the facing surfaces of stator poles and rotor ends are squared-off flat, or whether they follow the curve of the circular "donut hole" becomes important. Is the clearance 0.013" uniform all the way across like it might be with curved bits, or is it a "minimum" figure for the closest approach of the corners of squared-off facing ends?

I'll bet a "rotor crash" when running at speed could ruin your whole afternoon.

Haven't you just "shorted" the laminations and created a lump of iron, thus defeating the purpose of the laminations, which is to reduce eddy currents and associated heat?

   I'd wondered about that, but there again I've seen transformers etc. with a run
of weld across the laminations.

Are these welds that connect all the laminations together?
