The clear part in the center of the coils is plexi. I cut 1"X2"X3X8" pice of plexi. I cut slots on the sides of the plexi. I use this as a bobin in the center of the coil winder. The plexi pice stays in the center of the coil and is cast into the mold along with the coil.
The slots on the sides alow me to used zip ties to hold coil shape. Latter I replace the zip ties with white cloth tape. During handleing the coils expand a littel but the precut cut out in the stator form squishes them back into shape.
Next step is bearing and shaft assembly. Then its about time to do some RPM, prime driver requierments, volts at rpm, amps at rpm, watts at rpm, temperature of coil at watts for time running.
Ofcourse all these test will be done in star and Jerry Rigged. I can tell you quite confidently That start will run quite hot.
