Progress Reports on the ETF Rebuilding Project

Untreated steel is the best option. High heat keeps rust from progressing to the
point it will become a problem. And if the oven remains unused for any period of
time, heating it and or wire brushing it down will remove any rust.

You can keep a dehumidifier in the room to keep humidity levels down and
keep the bare steel from forming any oxide from becoming a problem.

I believe in time you guys will have no choice but to rethink how you will rebuild
tubes. And I am thinking the gun, stem, and pinch off will be changed because spare
items will not be available. I think in the future, guns will be rebuilt, and the neck
will have to be rewelded to the old tube envelope at the point that use to be the separate
stem, and the entire oven may need to be under vacuum.... Just thinking about how things
will have to be done when new guns complete with through wires and stem/pinch off's as
a finished assembly are not going to be available.... For that reason, you may well
begin to think about a really clean oven...
