Kurt's Induction Coil Farm


Here I just want to give you an overview of most of my induction coils, which, by good luck I was getting hold of.  There was no need trying to find those induction coils: they "came to me" (!!!): it was in consequence of some of my public Tesla/HV demonstrations, that I came in contact with the aged owners of these coils, who wanted to get rid of them. I'm  deeply grateful  to Mr. Rolf Schmid  (>86 in 2007),  to whom I'm yet in good live contact, because he's living in the same town, and to Mr. Jakob Kuster (>92 in 2003), whom I've never met personally, but had good exchange of ideas by letters and phone.
The construction of my own induction coils, in part together with hobby-friend Andi Saile, was another exciting experience, some of it being documented on my older webpage about induction coils . In the few images following, I also want to make visible, that all of my coils are operable...

The sparklength's indicated below are lengths, which I have tried, and from which, I  suppose, will not arise too much HV-stress for the partwise aged coils. The big coils were probably made for 30cm+ (12inch) sparklengths: I just dont't like the risk to blow the old nice coils.
