Perhaps I'm wrong,and I'm sure someone will correct me,but from what I see in your photos,there's this big carriage bolt coming out of your endcap.It also appears as though you are using this as a ground for your secondary?Could be the culprit as with this configuration you are essentially introducing a wire on the other side of your secondary former causing the insulation to break down.Just a thought.

Subject: [TCML] 1st Run

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.
