My 2-cents...someone is getting their jollies being a troll at FS. Hope I'm wrong though!

I hope you're wrong too lol.


Thanks for moving it, I was just about to ask someone to move it anyway.

As for Texas
Olney TX had a B series 1003 Near the Dollar General that I could not find.

Holliday TX - They have at least One B series Thunderbolt. Over the years there have been many photos of it taken.

Please keep these comments on B-Series Thunderbolts in the topic I made for them in the off topic section, thanks.

Regarding the heavily modified old unit idea...

oh neat thunderbolts are literally coming back with a bang.

Hot Dang! and here i thought someone was just blowing smoke up our rear ends!

This is on their Facebook Page.. it feels so real now. https://www.facebook.com/FedSigISG/

I think that instead of using belts to drive everything, they should use some form of chain. Like a bike chain, but encased in its own sealed off oil container, like a sealed bearing.

New design aye? They might have something up there sleeves, but it seems to me that you really don't need to change much with the original configuration to make an improved 'bolt. The only thing that I could see them doing to it to make it louder is making the port on the stator bigger and shoving more air and pressure into the system. They could wind the Model 2 motor to run on 48VDC and use something like a mosfet to chop the voltage to it if they actually want to give people the option of pitch control; not an expert on this, but this seems to be the way that manufactures control the speed on their drills. The rotator is already there with a direct drive solution and a DC motor. The only problem I could see is the blower, they would have to source it unless they plan on making their own. Granted it has enough grunt, they could us the 7 HP motor from the Eclipse series to drive it. The whole lot of it would run on 48 VDC like the rest of their mechanical sirens. At that point the only thing that would probably let the smoke out is the rectifier, since that's a good 9.5 HP or so that's pounding it vs the usual 7.5 or how ever much the rotating mechanical sirens use.

Even with all of that they would still have to pull something on the marketing side of things to give it an edge. If they can only get, say for example, 130 dB out of the thing and have it costing 1.5 times the price of a 2001-130, which will the emergency management take? The dB ratting sells big time which makes something like the 508 or Equinox look less desirable even when their lower pitch carries and penetrates way better; the 2001-130 will end up steamrolling over it. That said, most nuclear power plants use sirens that run in the 500Hz area, which is why the Beaver Valley and Perry plants adopted the Equinoxes early on and other plants with the 508, T-128, T-132, etc. If they can get these things to outperform a T-128 in range I could see plants buying these new sirens, granted there are any left operating AC sirens by the time this thing hits the market.

That's for an A-series thunderbolt not a D-series (just assuming that it will be D-series)... Not to mention that the newer rotator isn't there, oh and they aren't making a 1003 just the 1000T. If they make the 1003 I'll literally crap my pants.


The date says January 1982.
