If it's getting hot enough to make fibreglass smell, is it not hot enough to 
start doing nasties to PTFE? The thermal decomposition products of PTFE are 
definitely not nice - for the rig and for the operator. 5 inches by 2 inches 
sounds very like the coil formers used in the old TU5B unit for the BC191. I've 
never tried, but I wonder if it's possible with a small masonry drill to 
actually drill holes where you need them? I seem to remember suggestions that 
you can drill glass that way, but, from memory,  you do it under water to 
prevent resonance shattering the glass.
