Ralph Okon (a.k.a.
http://www.powerditto.de ) is putting together a group order for 40mm. diameter, 18pole statorlaminations. A minimum order of 5000 laminations is needed to start a production run. Minimum order per person is 50. One 0.20mm lamination (NO20 iron quality) will cost 0.5. Flux ring and frontplates will probably also be available by then. Keep in mind, this is not a business for Ralph, he's in the business of curing people :-)

I'm posting this in several lists/forums, think it's best if we all discussed/asked in the thread above.
