I tried to show a friend who popped over without success and felt like a fisherman exaggerating how big his catch was.
Anyone know what I mean? I badly want to reproduce it and grab some macro shots.

You can probably drill out the ends of the shaft and thread the hole to whatever size and thread you like.... that would be easy.....
What are the materials it is made of?
Hopes and Dreams....

6" x 2" rotor is made of aircraft aluminum and has stainless steel shaft, but the shaft is huge. I'm worry it may interfere in working setup. It wont bend, for sure

I'll need a 1/2" or less spacer between the wall and rotor side too. Just got home and have to get few things done, including pyramid modification (have some interesting observation with use of crystals - will post in pyramid thread later), multistrand for my solid state, start assembling cap pulser and couple more, if time permits.

I am green with envy I would love to build a SG like you are.
The problem with your shaft is dissapointing to say the least, all I can think of is maybe to use bearings that fit the rotor hole that have a smaller diameter central hole "the size you want" and have a new shaft made.
Cheers

After several builds based on large hard drives, pulleys and bike wheels I was finally able to save a $ to order this one. I have enough wire to wind 2 coils at most and enough transistors for such. Remaining 4 will have to wait a bit
The problem with your shaft is disappointing to say the least, all I can think of is maybe to use bearings that fit the rotor hole that have a smaller diameter central hole "the size you want" and have a new shaft made. You gave me an idea Leave those bearings, since the work very smooth and use a spacer tube in inner hole to accept thinner shaft. Still need a flange to be made.

Oh my goodness that is incredible, is it "just a coil" though, it's magnificent. I think it's more than a coil it's almost working art. The wavefrom is neat. And it's charging that battery good and proper. I can't imagine how a thing like that is made, I have trouble winding four wires on a spool and keeping it neat.
Awesome.

Another Starship experiment
Originally posted by blackchisel97 View PostI want to try another pattern tomorrow, trifilar and see if I can wind one wire -180deg. I wonder if this may allow me to pull something useful without other coil noticing
Update: I used litzed coil in "normal" bifilar self oscillating configuration. Waveform is nicer than my other coil and spikes are at 55V. Circuit oscillates at 10kHz and is charging well.

Thanks
