Picked up a Thunderbolt from Indianapolis,

[CDV777-1]

As far as I know all of the other sirens are being disposed of by Federal. They don't want to give them to just people because they don't know what we'll do with them. And they don't want to give them to communities in need. What happens is that say an old T-bolt from Indy makes it's way to a small community like Farmland. Now Farmland fixes it up but a piece in the blower breaks. So they contact Federal wanting a replacement and Federal no longer makes parts for T-bolts. So those communities get angry and give Federal a bad name. Atleast that's how it was explained to me.

Since when does Federal install sirens themselves? Don't contractors do that? I seriously doubt this about Federal being afraid of what someone will do with a siren. Either the contractor or the city will dispose of the sirens. What could someone do with a siren anyway? It's not like it's an old fighter jet or something. All a siren does is make noise. And how does Federal not making parts anymore give Federal a bad name? That just doesn't make any sense. Sounds to me like whoever was "explaining" that to you was full of it.

Yes, Federal doesnt install or service sirens directly, the dealers do it themselves. And the bit on the public getting the sirens is a load of crap, if anything, its that they want to make money off of a new siren instead of donating it.

As for the blowers, they are very common, as they were not only used in sirens. Roots may still make something very similar to what the Thunderbolt sirens use.

They do. One of the most common places you can see them at is as an aerator for sewage treatment plants. The smaller ones are used as superchargers on drag racing cars and hot rods.

I meant similar in output pressure and volume.

That is a great find! I know how long it took me to get mine, and I had to drive 5000 miles... I challenge you to see who gets his T-bolt restrored first... I'm aiming at 2064 if things keep as busy as they are

On the standpipe issue: You say the flange is on a 10' pipe, which isn't the easiest thing to transport. If you need, PM me and I'll send photos and measurements of the flange on the other T-bolt that isn't assembled yet. Also, I believe Archon has some standpipe pieces in Milwaukee for free, if he still has them. http://airraidsirens.com/forums/viewtopic.php?t=1624

Ok, several things.

Yes the siren in Downtown is a 2001-SRNB. It was one of only 2 2001's in downtown. Now there will be only 2001's.

Yes the flange is still on the rest of the standpipe in Indianapolis. The standpipe is stored inbetween a shed and a garage. I've got the piece of standpipe that was attached to the rotator box.

It's a duel-tone unit. If I remember right all of the 2001's in Indy are 1000-T's or 1003's.

It was a nice find, and I was very lucky to get it. Now starts the process of restoration.

Matt,

Ahem....I bet I'll beat ya both I need to do better about getting some photos online. I think I've figured out how I'm going to this this brush ring plate. I'll let you guys know soon enough on how I'm going to do it because I hope to start that tomorrow.

[Matt Hackler]

I'm sure you'll both beat me on getting our T-bolts restored. I'm excited to get started on this thing. I've got a weeks vacation coming up in Mid May and I plan on spending a lot of it with my 1000T. Also a small question that I probably know the answer but just can't recall. The plates on the blower call it a 1000BT, anything different than a 1000T? I'm guessing it was a later produced model. We were looking through old city records and I believe this one (although I could be wrong) went up in the 70's at some point. Indy had a batch of sirens go up in the late 50's and early 60's. Then a batch in the mid 70's and finally in the 90's they started with the 2001's. Just wandering if anyone knows the answer to the 1000BT thing.

B is for single phase.

Thanks to Adam P. for sending me the proper literature for the event. You've got to have a Thunderbolt manual to do any work on one.

The standpipe flange you can better see the difference in paint.

A very rusted begining to the standpipe. You can also see the wire screen that the city put on there to keep birds from making nests inside of the blower box.

Here you can see the rotator motor and gears from one side

And the other side

Where the horn attaches to the rest of the siren

The same kind of wire that was on the the blower box was put on the horn at some point. The original screen structure is long gone but I'm going to try to construct one.

The entire assembly and my workspace. You work with what you've got.

Here is the final picture. It looks as though it's been welded. I'm not sure if this is original Federal work or another Indianapolis addition.

I'll post more pics here regularly as I get more done,
