@ Steve

Is not more easy and cheap to use the a service like http://www.emachineshop.com/

I don?t have any mechanical machines, and don?t want to have it.

Just be aware that Emachines does have a setup fee of $150 just to get started.
Then so much a piece. If you only want ten or so, not so good a deal. Hate their
software too.
On the flip side, the parts are "all" the same and to tight tolerance. If I decide to
replicate one of these, I will most likely use them and just have someone else do
the drawing. Not cad oriented. Still use my hand drafting tools.

Well I'm not sure Emachine shop has transformer laminations.
Plus Jack big machine's valves are probably like 80mm wide so, that is if one would use thick laminations a total of 160 laminations a side, 320 for a complete valve, so thats 960 for the 3 valves. That is only the valves. The coil cores will also be 480 lamination. Plus the rotors also would be 480 laminations. But ya can obviously also build a smaller version. So lol lets hope they can guarantee a 0.1 mm airgap accuracy.

Hi Steven,

Good looking proto..,
Noticed your timing mechanism and was wondering how you plan to drive it? It occurs to me that Jacks' use of points takes full advantage of the HUGE BEMF he produces and would venture a guess that without it you'll get little to no torque. As Stephan suggests, carbon points on the commutator may well produce the desired effect.
Good luck and enjoy the adventure,

Carl
