Love that channel, actually listening to it now at work. The man puts out an absolute mountain of content.

Anyone planning on attending the Oklahoma Steam Threshing and Gas Engine Association show in May?

Not a steamboat meet, but it's a huge gathering of steam (and antique gas) engine enthusiasts and the general public. In the last show there was a pretty large display of odd homebuilt steam launch engines, and you can usually find someone interesting to chat up about the hobby. http://www.oklahomat...

Re: Back Acting or Return Connecting-rod Steam Engines

I love these back-acting designs. Such clever arrangements to be as compact as possible

Re: Reliable Monitor Plans

I would suggest you call Reliable and find out if anyone has built this hull. A revolutionary design that is very effective at dodging cannon fire, but the very concept results in a boat that is inherently not very seaworthy. If you can be OK with the seaworthy limitations, and want the novelty asp...

Re: Reliable Monitor Plans

Does anyone have any experience or knowledge of the Reliable Monitor plans ? I'm intrigued by the thought of building one in steel, but I'd like to know the community's thoughts before dropping a Grant. Any link Tom? I'd like to see what it's like. A search here drew a complete blank Sure thing! ht...

Re: DetroiTug's Tug is going together

All the mechanicals seem fine, just need to ultrasound and hydrotest the boiler. Five years ago, I adopted the regiment of ultrasounding every 5 years and it's due. I used windshield washer solvent as antifreeze, I'll see how that did. The steam car people use that as well. Ron Do you leave your bo...

Re: Theory question: Pressure/temperature limits

An antiquated way of producing hydrogen was to pass steam over a red hot iron surface, forming hydrogen and magnetite. I suppose that could have been what occurred in such an instance? Probably from an underfilled boiler, although I can't imagine a red hot boiler tube would be able to hold back the ...

Re: Theory question: Pressure/temperature limits

I'll scan and post the page later, but in one of the Audel's books there's a (purely theoretical) design for a quintuple expansion engine that takes 1500 PSI from the boiler. Ron is pretty active in the steam car community where they push pressures a LOT higher than we do, so he may be able to give ...

Re: After Coal?

One thing that may be worth taking into account when considering the economics of using oil as opposed to coal is that although the fuel itself is more expensive, will a launch really burn that much of it? A 4 hp launch, operating at a measly 4% efficiency, should only consume about 2 gallons of fue...
