Re: Another Sidewheeler Building

I don't suppose that we can talk you into installing two engines so as to duplicate a Thames paddle tug... That turning in your own length deal is a pretty good trick!

Re: New member

Welcome aboard! Stuart engines have a lot to recommend them, but since you mentioned scratch building, you might buy this book The Steam Engines of Ray Hasbrouck . It is also available on Amazon. Ray was an excellent craftsman, and his engines are designed to be built completely from bar stock, with...

Re: New guy on the forum

Welcome aboard Curt! I believe that you will find steamboating a most rewarding hobby. Unlike traction engines or live steam railroading which tend to only operate on club grounds, you are only restricted to where you can find water to float the keel, and are thus free to travel miles in the directi...

A Funny Looking Slide Valve

The original low-pressure slide valve in my launch engine needed to be replaced this spring due to heavy wear in the cast in T-slot that connects it to the valve stem, so I hogged the new one from G2 cast iron plate, and to assist with potential wear on the bottom faces of the T-slot, I made those p...

Re: Sidewheel steamer aircraft carriers in the Great Lakes

Coal burners as well. I would have loved to have been a fly on the wall when the newly assigned black gang walked into the fire rooms for the first time. These would be a great way to win a bet. All you have to do is to make a statement about the US Navy's coalburning, side wheel aircraft carriers...

Re: Upscaling a Hasbrouck engine

Note the similarity between the most efficient prop for a steamboat, and that for a human-powered boat: http://recumbents.com/wisil/hpb/prop/default.htm Some of the athletes are capable of outputs (for a short while) that exceed that of small steamboats. That's a cool site, thanks for posting the l...

Re: Upscaling a Hasbrouck engine

I had good luck using the formulas in Dave Gerr's Propeller Handbook. That's where I arrived at the 22 sq. in blade area for Reciproca's 17"x26" prop.

Re: Upscaling a Hasbrouck engine

Somehow I don't know how that calculation can come out to 5. Here is an actual example of a PLAN calculation of a 2 cylinder double acting engine (1902 Toledo) RPM = 220 200 PSI Boiler Pressure 3" Bore 4" Stroke You could try to increase the RPM for example, but depending on the size of the propell...
