That Model A looks great! :thup: How did you get the chopper and stator so clean??

[quote="Mark N"]I know there are some STH-10s in a prison in Arizona, and there had to be some on Alcatraz...[/quote]
Hmm, I live in AZ. Where is this prison at? Do you know?

Thanks again for the insights, Jeb. Both of my 1000's have the thick-beaded and uneaven, fat welds on their horns. This proves, even though I already know, that both of my Thunderbolt's are pretty old.

Hmm, Jeb that's interesting! Thanks to most of you for solving the questions about how my SD-10's worked, since all of them having Bell Systems telephone relays to close the circuit of the motor starter.

Hmm, I didn't know that happens if you just use a shop-vac. That's what I've been using, since I still need an actual blower part for my thunderbolt, as i just have the motor and frame sadly. And it doesn't seem to starve, its been doing a great job, just nowhere near what I would like it to do. So ...

Does anyone know what happened to Palo Verde Nuclear Power Plant's system of E.O.W.S. 812's and 1212's? I do know that they DOWNGRADED to ATI's I want to get some info. I don't know if they are sitting on their property, or scrapped? Anything is helpful, thanks.

Cool, I like it, show some more!

If you are still interested, I have pics and locations of 15+ sirens of Utah...
