In response to the 2 12 volt batteries in the engine that you said are wired in series, then that would make 24 volts which obviously would fry the q. I think you meant to say that you had 2 12 volt batteries wired paralell, which would keep you at 12 volts but add the much needed amperage to take c...

killer pics man! is that a gear shifter sticking up off of what would be the tranny, do you know? i would think that direct drive would be what turns the rotor, but the start up load would be hell on the starter. that motor could easily be swapped out and a good used motor dropped in for probably a ...

that thing is INSANE!!! great job would be an understatement. i have been thinking about doing the exact opposite, which would be to build the largest, loudest t-bolt possible. i have a 6-71 roots style blower from one of my hot rods and i thought about what kind of displacement that thing would put...

I did a helluva growl w/my tbolt on halloween eve around 7 or so, and haven't sounded it since. I'm sure at least a follow up at midnite should fit right in. I think I'll start by winding the chopper to full speed then throw the blower on, then kill the chopper while leaving the blower on for the fu...

thanks man, the thought occured that with the huge volume of these images of america series books out that there should be a good source of pics of sirens for all of us.

Here is the link http://www.flickr.com/photos/59737609@N00/271985985/ This feels like th dog liftin his leg for th first time...

If they were operating it manually from the stack of toggle switches in the rcm cab then you can easily control what kind of output you get, for example I will start with just the chopper only, then after it hits peak pitch then I'll hit the blower and that will throw a huge roar out only at peak pi...

Thanks to all the compliments from everyone, and I would like to think that hopefully some folks on this site who own large stationary sirens would be able to purchase some land out in country to where they could sound off when they want. Anyway that fed sig tbolt logo you see is nothing more than t...

its a 1000 on the oval black fed sig. plate it says model bsc that means its a combination of a model/seriesb and model/seriesc with s standing for single tone. as far as the cabinet with the ar timer what you are seeing is a siratrol box which is for radio communications activation. neither the tim...

Hi everyone, wanted y'all to know I've uploaded some more pics on flicker. com. So when you go there just look up matty8371 and hopefully you'll see them, and once again I need not say that I cant figure how to get these freakin things over to this board, so maybe one of you can snatch them and post...
