Keep in mind that the water temp. affects the size of the condenser that is needed, as does the speed of the boat. In less sheltered areas here on the West Coast, the water temperatures are perhaps 55F.... but lakes and rivers are often much warmer, esp. on the surface in the summer, and hotwell tem...

I'd only use it to help keep vacuum during docking; one generally has too much steam then anyway
Normally they use too much steam in our small plants, and they do heat up the hot well when run too long.

Don't underestimate the simplicity and reliability improvements you'd get from a big single cylinder uniflow... with a overhung crank, you can easily use roller bearings for the crankpin, and mains can be tapered roller bearings or babbitt if you prefer. With poppet valves, a proper maneuvering cut-...

Well, I ride my bicycle to work year around down here in "south America" :-), but since it's down into the 40s by the time I go home this time of year I wear some warm clothes... it does freeze here once in a while, but never really a hard freeze. Once or twice I've seen forecasts for high twenties,...

And I too would very much appreciate a copy of your paper....

I've done a fair amount of reading on the topic in various books, but this is perfect - thanks! My college German really isn't up to technical topics so it's great that there's a translation. Google Books has certainly made collecting info on steam engine much easier than it was 20 years ago. - Bart

I will say that providing some internal lubrication is a good idea, particularly if you run the engine hard. I've always used some (whether by design or because on my old compressor conversion the crankcase oil would get past the rings ). Yes, you do need to give some attention to oil removal in the...

It's not so much tradition that interests me as the look...steeples don't grab my eye... You mean this steeple that doesn't grab your eye? :shock: http://www.northweststeamsociety.org/BlaineSteeple.jpg Photo courtesy of Dick Vennerbeck That of course is the sister (brother?) engine to the one in Je...

I need to update these pages to add details about the
new engine.... http://smaalders.net/bart/boat.html

Best of luck to all affected by this... http://news.bbc.co.uk/2/hi/uk_news/default.stm
has news... sad to see the Blue Bell Cafe on Coniston Water flooded, as my wife
and I happened to eat lunch there last year...

Best of luck w/ the boat!
