Re: [TCML] Copper / Tungsten Electrodes



One way to make the rotor would be to use a disk of solid aluminum plate with an insulating hub. Drill to fit holes for each stud which can be held in place with setscrew in edge of disk. Plenty of cooling due to air flow over plate.

Phil, All
   I bought 1/4"x 20" pure tungsten $ 60 , from Midwest Tungsten, here in the states. Used a lot of dremmel cut off wheels to get a 8" propeller with 4 stationary contacts that are 1/4x1" mounted in aluminum holders.  Scored the stock about 2/3 and broke seemed to work for me.   Used my green wheel to round the edges, but think next time will let nature do it. Very pleased with the run time before adjusting.  This is small coil , 900w power supply .
    Building a new larger, 1.5hp or 3 hp, robust rotary and would like to know how you made your inserts/holders in your rsg disk . Have lathe and mill.  Any advice would be appreciated .  Have been looking at pics of other TC's and would really appreciate any suggestions.
                                                                                  Bob Massa

  Has anyone had experience of the 90% Tungsten rods, as opposed to the 70%
that I'm currently using?
(90% IS available apparently)
I thinking of its ability to cut with a hacksaw or ordinary cutting disc and
even machine, if anyone has had cause to.
