Another Westinghouse H840CK15

John Folsom was kind enough to give me a copy of the winding data for the replacement transformers that he had made available. Good news is my own calculations were close enough to have resulted in a working part if my first two attempts had succeeded. No 43AWG wire was used, so the winding resistances should be close to the Westinghouse part. Now I just need to wait for the new spool of wire to get here and start practicing with the machine again. I tried two more test winds of the primary which appeared to have turned out OK, but that one is easy since it's only a few layers of wire. The problems start with the secondary simply due to the number of layers of wire and insulating tape needed. Just a bit of unevenness from a wrinkle or air bubble seems to get magnified when winding the new layer over it. I probably won't get it 100% perfect, but I think I can get it close, at least enough to recreate the transformer. Apart from a few wax capacitors, the transformer is the last hurdle I have at this time to getting this set running again barring any unforeseen problems.
