Re: Post your Mystery Sirens here.

Strange that the plant its on is very clearly active but unlabeled on the map. It probably lost its cone to high wind.

Re: VC Summer Nuclear is Decommissioning their sirens

And I am sort of curious as to what you are basing your comments on. Before he retired My grandpa worked for Mobilcomm, the guys who work on Motorola police radios and Clermont county's sirens. So he knows all about weather radios, EMS radios and a fair amount about storm sirens. I know sirens can ...

Re: VC Summer Nuclear is Decommissioning their sirens

While you do make some good points, keep in mind the NRC recommends multiple forms of warning (including sirens) and not everyone can check their phones at work. I'm a welder, my neighbor is a judge, my aunt is a nurse and most people aren't on the line 24/7. When I wrecked my truck, I called my par...

Re: Overdrive pulley for thunderbolt Blower: would it work?

You need to be careful with doing this and if you are considering it, you need to be reasonable with the change. Those roots blowers were designed and balanced for a certain RPM range. A blower on a car / truck engine was designed to be run at a varying rate as the engine was sped up and slowed dow...

Overdrive pulley for thunderbolt Blower: would it work?

I was discussing with my dad how Thunderbolts are supercharged (Like Detroit 2 strokes and Hot rods) And this raised the question of if the supercharger on the Thunderbolt would accept an overdrive pulley (smaller pulley to make the blower spin faster). Assuming the motor driving the blower would ta...

Re: A Fresno siren system "mystery"

Let's not forget Clermont county's model 5QC that hasn't been run since the 80's but started ok in 2018 when the 1212 prototype that replaced it got struck by lightning. It doesn't sound good but it does sound.

Re: A Fresno siren system "mystery"

Some sirens are just used for storms and not tornados. The ASC T121 at the Kenwood country club is privately used for heavy weather on the golf course. If there were a tornado Hamilton county's sirens would sound, and those cover the area pretty well.

Also that's the entire purpose of thorguards.

Re: Post your Mystery Sirens here.

Looks like an older secomak. A company called sirenco still makes sirens like that today. Not sure which it is exactly , here's a link to their website: https://sirencosirens.com/sirens/ I know of at least one Federal Signal Model 3 over in Germany, and this resembles a model 3,5, or 7 without the h...
