Building a Steam Library

What books do you recommend for building up a steam library? I've just bought Modern Engines and Power Generators, Audel's Engineering and Mechanics set, and Machinery's Handbook, but if there's anything else you can recommend I'd love to hear it.

Re: Engine Indicators, Power, Tuning

The fussing over whether all six blocks get equal torque I think is a red herring. I think they share it equally but I could be persuaded otherwise. ANS THE THIN STEEL BAND HAS DIFFERENT ANGLES FORCING THE BLOCKS AGAINST THE WHEEL, SOMETIMES THE BAND PULLS PARALLEL TO THE WHEEL ON ONE SIDE, THUS NO...

Re: Engine Indicators, Power, Tuning

1.35 horsepower, but I encourage someone to poke holes in my result. Methodology: I figure that since there is no actual work being done, all the energy must be dissipated as heat. Given that there is a distance of 17 inches (1.41667 ft) from the wheel to the tensioner set at 20 lbf, it can be known...

Re: Engine Indicators, Power, Tuning

This Prony Brake was actually made to find the horsepower of a small uniflow steam engine. It worked very well, but several graduate engineers at a large firm specializing in power plant design, could not find any answer to the stated question! Alright, I'm intrigued. What's the question?

Anyone got a clue as to why I see no images??? :?
I'm having the same issue. I posted a test in the testing area, is that working for you?

Valvegear Simulation Software

I don't know if this is well known, but I recently found a website (http://www.billp.org/Dockstader/ValveGear.html) with software available for simulation of more or less every valve gear ever used. It's meant for use with the live steam community but it's still been pretty useful for me, hopefully ...
