I was afraid of the Helander prices. I'm going to buzz Jon. Taps are out, but the plugs are a common hardware store (Lowe's) item, albeit maybe not in all sizes.

I'm thinking variac with the 1/2 HP 120v motor; think it'll work? I need a cheaper option than $150. Even a belt or chain drive with stepped wheel would be cheaper than that converter.
Keeping my fingers crossed on the blower; am being outbid. Hopefully the seller has more (been listing them for a while now).
Good find on the concrete former; local? Can we split one, or is 6' too short? Darn, it's a bit short... Really need 7 feet, at 32".
I could make bulkheads from commonly available plexiglass sheets, cutting and stacking multiple parts. A bit tricky, but cheapest of all. Thinking fiberglass & resin to seal the bulkhead to the tube. I'd have no problem using JB Weld on alu (the stuff is available in larger quantities).
I believe that standard/common screens are of the 75 or 67% opening, variety. Again, cheaper to stack them, and combine an egg crate. i.e. 2 stacked before the egg crate, then 3 stacked after. (duplicated on both sides of the nozzle wall). Any thoughts?
Am planning a stop for the phenolic this week, and possibly some surplus shops for the egg crate, time permitting. I believe that CDscrapmetal is closer to you.
