Thanks for the description and pictures Jack.

Over in Lake city Pa (west of Erie) WAS copes vulcan company.
I knew people that worked there, and they talked often
of building these things.

I have heard of some extremes in these like a 20 or 30' long lance,
and having to survive some serious temperatures.

I had a general idea what these where/doo, based on peoples
hand motions/scribbles, but this write up of yours makes it
all clear.
