Al, the time period sounds about right although I would think late 40s since I tried building one before Uncle decided I needed to go to Ft Jackson for a couple of years in March of 1951. [img]/ubb/images/graemlins/frown.gif"%20alt="[/img]

Dampfwilli, you right, those things make heap plenty of noise and run red hot down most of the tube. [img]/ubb/images/graemlins/crazy.gif"%20alt="[/img] Fire hazard? You better believe it!!

In roaming around the 'net I found a site where the people make such devices, they run on propane. There was one in particular hooked to a go-kart frame and would actually propel the thing down a road. I don't think these were pulse jets but the discussion about these thinks was that they burned a lot of propane and made lots of noise. I think one link was about a propane powered beer cooler. The propane exited a 5 gallon tank so quickly that it would work to cool the beer.

You must not be crazy to play with steam, but it helps.

Dampfwilli,

I'd be thrilled to get a copy of the drawings if you don't mind. If it's still possible to get them, please send them to: [email]vordos@tds.net.[/email]

Thanks,
Harold

The Union Pacific had a bunch of gas turbine locos in the 50's and 60's, Unka Jesse. As I recall, the last batch was initially rated at 8,500 HP and was uprated to 10,000 HP. Big Blow they were called. I believe that 10,000 HP is way ahead of whatever is in second place in the prime mover horsepower race.

You could model one of those -- with a miniature jet engine -- for Mid-South. Maybe use a gas turbine from a helicopter.

Charles, the "Dixie Chopper" lawn mower company put one of those helicopter jets on one of their mowers, hence the motto "World's Fastest Lawnmower". I bet I could give those hotshot guys who turn up at Mid-South a run for their money!

If you ever get a chance to visit the Army's Aviation Museum at Ft. Rucker, Ala, they have an itty bitty helicopter with two itty bitty pulsejets mounted on a pylon that made the thing go and they are not a whole lot bigger than what Charlie is talking about.

Speaking of museums, did you know that the Confederate Naval Museum is right outside Ft. Benning, Georgia in Columbus? Some right interesting Steam engines in one of the gun boats they are re-building.
