| Tube-thermal-insulating workshops, like the one of Iraklis Galanis, in Basel, Switzerland, can feed the tesla-coiler with robust toroids at a very reasonable price (SFr.400.- / ~ US$ 245.- for my 160cm/40cm toroid, shown below). Up to now (June 2000) I own 5 toroids of this kind: 2 pairs, each of size 70cm/20cm, 80cm/22cm and one 160cm/40cm, from this workshop. The toroids were made according to my coarse definitions. I have very good experience with these toroids, despite the non-ideality of the bulged-edges..., - taking > 2m (~80") sparks from my 8" twin-system. They are much more robust than aluminium air-duct toroids. The "fish"-form-gauges for my 3 kinds of toroids are already at hand. Sooo...Galanis, not yet owning an internet page: If you are interested, you can direct your questions to me, Kurt Schraner...,or looking at your local tube-insulator's workshop. |
