The Siren Board

If anyone needs a replacement wire fitting for the chopper wire on a Thunderbolt, here is the replacement I bought from Home Depot. The price is $2.24 as of 2/21/15.



The 1/2" fitting is the size needed (on the left).


Here is what it looks like once installed.

Brushes for the large single phase Federal sirens w/ Northwestern and GE 7.5 HP motors

Anyone able to find bearings compatible with a STH 10.. because I will be getting a chopper and a stator for a STH 10.. but nothing more then that.. So I can't do drill runs.. so I would need bearings.. I plan on dropping around 30 on it in the future.. if not a BIT more.. -More details on the siren in a different post later on-.

You don't just need bearings. You need the whole rest of the siren from what I saw on the auction page

If you are talking about this siren:

You are gonna need a 10 HP motor for this to mount to, the chopper rides on the shaft and bearings of the motor. You can't just buy bearings and have a siren. Also, i assume you are talking about spending $30 on this, you are going to need a lot more than that to get it to run.

Oh, I am referring to that.. but I saw it on Craigslist... Anyway, I don't need a working motor I just need something to make Drill runs possible.

Well then go to your nearest scrapyard and get you a cheap junk motor. They probably wont let one go for 30$ though.

I don't think it would even BEGIN to fit on a STH 10 chopper/stator..?

There is nothing special about the way those motors attach to the rotor and stator. Just find you a junk 7.5 or 10 horse motor with the same face/shaft diameter as the original(i'm sure you could find this info on the Board), put the thing together and run it up with a drill like you said you would.

Sorry to bump this old topic but the indicator lights that are used on the AR and AF timer is called the Leecraft Snaplite. You can find the indicator lights here. http://www.ebay.com/sch/i.html?_odkw=le ... e&_sacat=0 .
