Re: [TCML] 1st Run

I have done that before. =( 
My solution was after making a new secondary was to epoxy a thick acrylic disk on either side of the secondary below where the wire goes threw the PVC essentially sealing off the inner portion of the tube then i put a nice layer or resin on top of that on each end. then put a second disk on that held the bolt and RF ground and toriod. 

it looks like you also got external damage. that has never happened to me so i cant speak for it. 


Thanks,

1st Run, not so good. Was really looking forward to seeing my work come to 
fruition but it was so short lived I didn’t even have a chance at the camera. 
On the first run I saw more than a dozen 15-18" streamers all around the top 
toroid, that was taping around the 9th turn. I didn’t realize how hot the 
primary would get. I could not touch the clamp on the primary for several 
minutes. Everything looked great at this point. I tuned a half turn in and 
started another run at about 60% power but didn’t see any streamers at all. In 
fact I started smelling something burning. At that point I turned everything off 
and found the source of the smell on the far side of the coil from me. The 
secondary had a catastrophic failure internally. Photos here ->

I guess I’m going to be winding another secondary but this time with a different 
design; I truly believe the design caused my failure and not some contaminate 
within the PVC tube. So maybe the correct design for a secondary coil is to not 
have any “ANY” external connections to the windings internally to the coil form. 

Best thing I can say about last night; Mr. Butters didn’t make a show…. 

Next is always better.
