Greetings Harry,

   Be careful with the polyethylene pipe.  I recently wound a secondary 
on 10.5" polyethylene sewer pipe.  Didn't even think about the color of 
it.  Unfortunately, it was black, and it conducts.

   You might want to pass the the polyethylene pipe up if it is balck.

Later.

PS  I also built a smaller coil out of 4.25" PVC.  I get 18" - 24" arcs 
consistently, with an occasional longer arc.
