Hi Daniel,
Wow....as per usual, your craftmanship is excellent! i take it that you have designed you primary that way so as to mechanically adjust the tuning whilst the coil is functioning?
Yourself and Finn are becoming great pioneers in the TC world, i look forward to seeing more of your updates!

Thanks for the kind words Mel,
Yes I make the primary this way because I need the arm with carbon contacts to slide on the outside of the primary winding. I really hope I can make the arm and contacts in my Christmas holiday, but unfortunately it's winter now, and I cant take the darn coil outside to test it when I'm done...
This idea was something Finn and I discussed a while back, and then Finn pushed me into doing this project:-) The plan is to do something similar on Thumber at some point, but lets see how my â€prototype†works first... This is REALLY a big project, hopefully I´ll be done with the mechanical parts sometime in January, and then I just need to make the drivers for the motors, new MMC, and maybe a new bridge with CM600... So if I'm lucky I will be done sometime around summer next year:-)
I just got a big 3phase variac build in a cabinet on wheels, with fuses, on and off switches... for FREE:-) So that is one thing I don't have to worry about any more...
Coronafix,
Oh yes, it's some heavy gear I'm making here:-) I don't need a crane at the moment to move it around, but when it's done and it has to be moved from the shop, I would wish that there was a elevator in the building I am living in:-)

Hi all,
Friday I did a prototype high voltage insulator on my lathe, it is made out of POM-C with a toolbit steel that I made by hand.
This is the result:
I want the primary coil to be “flying†on five of these insulators, so the arm can slide on the outside the primary, without bumping in to anything:-) Tuesday Finn will be coming by the shop with the materials I need to make the arm, so hopefully I will have that part done before new year...

Hi all,
Just a little update on the project, but unfortunately I didn't bring my camera to the shop today, so I don't have any pictures to show.
Before Christmas I milled a internal gear in PVC, where the arm for the tapping point will be mounted. This is now mounted on the coil with the motor that will be moving it around, but because of lack of resources it's not a stepper motor, just a normal geared DC motor that I will control with PWM to adjust the speed.
Today I welded the the base for the coil in Aluminium, and mounted some wheels on it, as the coil is getting really heavy, and is becoming a problem for me to move it around:-)
So what I need to do now is:
Make the insulators that will be holding the primary.
Make the tapping point with carbon brushes, but I still need to do some CNC milling on them, so they will fit nicely on the primary. (Finn brought some rather big carbon brushes to the shop, they are probably from some really heavy starter motors or something)
Find some money to buy a new MMC... If there is some European coilers that will be interested in a bulk buy please give me a PM, or we can start a thread in sale and trade. I think we can get a nice price at Mouser, if we buy enough of them:-) I need a lot, as the impedance of my primary circuit will be around 10 Ohms, and I will be pumping 1400Amps through it...
And make a motor driver... This is something I will start on this week:-)

Hi all,
It's been a while since my last post, but I have been busy and haven't had time to do anything before last night. This is just a quick update, as I will go to work soon.
Last night I made the PVC high voltage insulators that will hold the primary coil, it still need some work but I will be done with most of the mechanical parts by Friday.

Hi all,
Just a couple of photos of the assembled primary coil, I am almost ready to move it from the shop and home to my apartment to work on the fiber optic motor controllers.
I will start on the tapping point today, and hopefully it will be almost as cool as Finn's:-)
