Secondary winding frustration



Original poster: "RIAA/MPAA's Worst Nightmare" <mike.marcum-at-zoomtown-dot-com> 

In the pursuit of ever longer sparks (and for a challenge) I'm building a 
hand held TC (a la BH-10 vacuum tester only bigger) with a high surge 
impedence to lower sync rotary gap losses. Realized really high 
voltages/low currents (30kv+ 10mA) are out of the question for a portable 
handheld unit due to weight, so I decided to canibalize 1 of my other coils 
for its 120-7500/40 nst's. Anyway, I have a winding jig rigged that's 
adjustable from from ~10-120 rpm assuming I don't go over the 90 vdc rating 
of the motor. I'm attemping to wind a 3.75 od acrylic tube with 19" of 36 
awg (175 tpi/~3300 turns according to my wire table). I was going to use 
39awg, but that would have made the Fres down to less than 87 khz with my 
8" sphere (want it to where it barely breaks out or doesn't without a 
breakout point, hope that's big enough) and out of range of the primary. 
Anyway how is this stuff kept from breaking when winding? It's hard to find 
tune the tension to where it's tight but not stretching. I don't want a 
solder joint (or lots of them) in the middle of the coil so every time it 
breaks I have to start over (aggravating if this happens with over 1000 
turns already on it). I'm thinking of adding another moter to unwind the 
roll (fresh so weighs 10.5 lbs and has quite a bit of inertia). I can't 
imagine how a commercial winding machine does a clean job of this. Any 
ideas/suggestions appreciated. Up till now I've never dealt with anything 
smaller than 30awg.
