i refuse to be defeated by the hard drive crap-out, therefore i will complement Finn and Daniel once again.
the copper work on your bridge is MASTERFUL in both form and execution, i also did follow your links Finn, and yes i found your motor pics, and your gear, bearing, and rotating plate design looks sound.

Oh well, some folks have always complained that i repeat myself, but now in have an excuse here....hehe
Hi Finn, i've so enjoyed this thread from its begining, your work is a masterpiece as per usual. and the info you'll get will be of great interest to us non mathematical folks who would like to understand the practical relationship between spark length,coupling and tunning, and all done in real time!! So congrats to you Finn and Daniel for some excellent work!! All the best, Mel.

Finn has always been famous Dr Spark!! Way back with his first adjustable tap TC. Not sure if he still has that page up anymore. Well done Finn, I believe that you have recently advanced DRSSTCs to a new level of Brilliant!!

Nice work this is awesome. This thing gives Steve Wards DRSSTC2 some competition! I have two questions. First of all, about the toroid, were the rings already circular when you got them or did you have to bend/shape them and where did you get them from? Also regarding the bridge, where did you get the 40N60 bricks from? I thought those things were classified as "obsolete" by Fairchild and so they are not manufactured anymore.

They were straight, as in full 18 feet lengths of pipe. We had to bend them ourselves.

You would be very envious, if you saw my stash of parts, aquired over a 10 year period. Period But note that Thumper uses CM600 silicon.

Cheers, Finn Hammer
I thought it said on the first page that the bridge was 40N60s.
Do you have a picture of the process you used to bend the pipes into shape? How did you manage to keep them so perfectly round and what pipe size did you use?
