I have a wood-frame motorized kick wheel which currently resides in the
basement. Out of curiosity I checked the wheel head with a level and found
that the 12" diameter wheel head is off level by about 3/32" across the
head in a diagonal direction. As this type of wheel is difficult to level
(needs many shims) I would be interested in getting opinions about how
fussy I should be in levelling the wheel.
The wheel is off level because of the poured concrete floor. While
spinning the head has no visible wobble or runout.

Clint, if the wheel head turns true, with no discernible wobble, that's really
all you need to worry about. The floor would have to have a significant slant t
it to affect your throwing and then I'm not sure that it still wouldn't be more
an optical processing problem than a real one. There is a ghost town (tourist
attraction) out side of Barstow CA that among other things has a special buildin
that you can go into and the built the rooms sideways, nailed the pictures on th
wall sideways, nailed all the furniture down, everything slanted the same
direction so that your visual perception of what is up and down is in conflict
with actual gravity. People fall down in there.
As long as the shaft and wheel head are true, being perfectly level is not. (aga
assuming that we aren't significantly off.

Not level? NOT A PROBLEM!!! As long as the wheel spins and you are pulling the
clay parallel to the spindle axis, the pot will still be straight up when put on
"level" surface.
