Hello John,
Looked at your files and I say, Very nicely done and like mentioned by others, Really liked the face !!!
I see the drum is, just being used as a housing, and the magnets spin inside that, I wonder if the drum was necessary, as you have steel pole shoes in your coil assy -- so the metal in the drum acts more as a means of securing things,and prerhaps a bearing holder, but the mass might help and protects things !!
Anyway, nicely done and we look foreward to seeing the output figures, hopefully you are now busy, whittling out blades !!?? Bill H.....
