  Fishing line sounds like a good idea, and can be used later to catch some lunch.
  We already know about what wire gauge and former size. We don't know what is the correct frequency matching to shoot for.
Neither did Akula when he first started.

Nick,  i agree, i count 8¼   0.1us sections, so 1 period or cycle is 0.825us.
Feeding this into the mentioned website, i get 1212KHz = 1.2MHz, see screenshot.

Yes, you need to very tightly wind this wire, then apply some fixture (tape around it, varnish, etc.).

It was T1000 back then who mentioned/adviced to use spacing on the secondary kacher to increase the frequency.

And Yours Truly is advising you to avoid high-k dielectrics between turns of a winding, if you want to increase its self-resonance frequency (SRF).

High-k isolating materials increase the inter-turn capacitance and decrease the SRF.
Low-k isolators (such as air) decrease the inter-turn capacitance and increase the SRF.


For example: If you fill the inter-turn spaces with silicon rubber you risk decreasing the self-resonant frequency by 300%.

  So, is there a problem with spraying varnish on the coil, as the mag wire already has some insulation coating on it.
  Is clear 2inch wide tape going to be a problem?  Teflon tape, maybe?

    Good to know that I'm up to 1.2mhz, from 700khz or so, originally.  And my device is responding differently, I just need to find the right frequency match to trigger this sync to the grenade coils.
    So, I guess that in order to be able to reach 1.5 to 1.7mhz, I should remove some more turns, and shorten the secondary coil again, to increase the frequency? Or not?
  I'll also tighten up the turns, so they will stay in place, while moving the antenna coil around above it. I left them somewhat loose so they would be easier to position. As they won't be able to be moved if they're too tight.

   Good advice, thanks Verpies.
  Thanks to Itsu, Gyula, TK, and all.  Nice team, I wish that you were all building this type of device, as well.

Yes, that should work.      Make sure the windings are evenly spaced.

Tesla coil builders use  polyurethane varnish (severall layers), so that should work ok i guess.
