Re: Favourite cylinder lubrication

I believe Cyberbadger purchased a few gallons of Chevron W460 a few years ago to try in his engine, I do't believe he ever gave a report on how it worked though.

Marina Difficulties?

Has anyone experienced difficulties when navigating a marina? Specifically in regards to the fuel docks, and the prohibition of flame in those areas.

Re: Con-rods and length

With all the concern about deformation and weld stress, why not build up an engine using threaded connections? It seems like the easiest way to avoid weld issues in the engine would be to avoid welding the engine at all.

Re: Prop Step Up

It has been "Shake, Rattle and Roll" in my old hull above around 350 r.p.m. but the motor mounts were pretty much a trampoline. We'll see on the new hull. Otter has the same problems w/ her 2.5" x 2.5" single as the counterweights are too small; the old 2" x 2.5" single acting twin was much smoothe...

Prop Step Up

Is the use step up gearing for the propeller common in steam launches? I've only found reference to it being installed in Cyrene , listed in The Steam Launch , however I am unfamiliar with its implementation other than that a chain drive was used. Given that our engines are typically operated at low...

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...
