Correction to ace motor dead zone measurement, on Centers

["Tesla list" <tesla@xxxxxxxxxx>]

Original poster: "Jim Mora" <jmora@xxxxxxxxxxx>

After reviewing Terry?s notes, I now know the 
measurement is taken from Center of the winding 
in the dead zone area which are adjacent to each 
other in this case. The heavier coils break out 
in both directions. That distance is 3/8? (was 
3/16? side to side). Hope that?s right..

Ace Hardware: 1/3 horsepower ~$29.00. 10 minute 
disassembly The rotor cut looks easy enough as it 
is small. 3450 RPM. It Looks simple to modify 
base yoke/housing (aluminum). Cut off the two 
mounting studs from outer housing; reattach with 
heavy duty hose-like clamps or Large muffler clamps for phase adj.

I will post how well this spins/locks a 11.5?, 3/8? G10  disk when its done.

Any suggestions how to set this up via a dual 
trace scope with ext triggering 120 or 240 bps 
operation?  Magnet Well attached to a spinning 
electrode ? small fixed induction coil, trigger 
the scope from the leading edge of the line 
voltage, attach the other trace on the pick up maybe?

I seem to remember a fluorescent lamp acts like 
strobe? Black light with a fluorescent timing 
mark? I have looked at Terry?s cool RS strobe solution.

Please advise if I am incorrect on the 3/8? flat depth.
