you're a bit like Archimedes Plutonium.

yes, they are similar.

my old fan was peculiar.

well, mine is sort of round, if i drag my measuring wand all about the diameter, i don't get a consistent several inches i get a variety of responses for the radii plus or minus about a half an inch. the coiling part has noticeable eccentricities but it is sort of round.

for one, your description of my fan claimed it was self lubricating with "oilite" type bushings, it was not.
like i said, my old fan was somewhat peculiar.
you may be a bit like Archimedes Pluto, at least, you didn't say;
"no, your fan could not possibly have been one that needed to be oiled."
but, more importantly, in this case, you are wrong about Pluto. you said Pluto was off in [his] own little world where facts mean nothing simply because [he] asked me if the copper windings in my motor coil was close to being spherical.
here's what Pluto said;
==== Tell me, are the windings close to being spherical in all? ====
and then you say;
=== As usual he is off in his own little world -where facts are not important. ===
so, this is the sort of question and answer period here;
AP: "are the copper windings in your motor close to being spherical?"
DK: ""as usual, you're off in your own little world where facts mean nothing""
