[Amps] Chimneys

[Will Matney]

I am working with a company now who makes different electrical tubings. 
They mentioned one with a heat rating of 400 deg. C. (752 deg F.). Also 
saying they could match the diameters I need. This tubing is made from 
Kapton and their specs give a good HV insulation resistance. If this 
comes about, these chimneys could be way less expensive than ceramic or 
teflon. If anyone may be interested in this, let me know as I may start 
making them if there is enough interest.
