Greg, Thanks for the compliment. From what I understand, a Beavertail stern is different from a Drake stern in that the Beavertail is a continuous curve around the stern while the drake stern comes to an apex. The Beavertail also has a shallower angle to the waterline (flatter stern) The bits below ...

Just wanted to brag a bit on what the UPS man just delivered. It's marked 18 24 Geo. E. Taylor St. Paul MN. It's quite the chunk of bronze. Should be perfect when I get a hull to put it on. I know I'm probably doing this backwards but the prop came up and you don't see these very often. This is the ...

From Wikipedia, the free encyclopedia A pressure volume diagram (or PV diagram, or volume-pressure loop)[1] is used to describe corresponding changes in volume and pressure in a system. They are commonly used in thermodynamics and cardiovascular physiology. PV diagrams, originally called indicator d...

These may be a bit closer but the handles will be different. Maybe you could rework that part.

Not to nitpick but... One should do a proper gauge glass blowdown at least once every steaming to ensure the glass is reading the correct level. Proper procedure would have found the issue the first time out since the lubrication. There have been many many boiler accidents partly due to operators f...

I haven't tried it on steam as I don't currently have access to a boiler. It's on the list, as the engine gets closer to completion. My understanding is that there isn't much difference between air & steam, only about a half note tone difference but there will be a big difference in the "quality" of...

As promised: http://www.youtube.com/watch?v=KMD1T9GXsbQ http://www.youtube.com/watch?v=Uvbom4-4Ejw I used the air hose instead of directly from the compressor to the whistle and I think it is starving for air volume. Take a look at this site if you haven't already http://www.crosby-steam.com/cow.htm...

I second Ron's recomendation of the Yahoo group. I havn't been on it for awhile, but it's how I got the information I needed to build the bells for my whistles. I had picked up to whistles on flebay, one had a damaged bell and the other had a bell that was scabbed on from another which was too big f...

Monel rods are apparently used in well water pump service so John has a basis for his choice. I'm sure he was going for the corrosion resistance. With the rest of the engine design as any indication, John definitely knows what he is doing. The guys on Smokstak had some good threads on this subject a...

I choose the chromed rod over mild steel because the surface finish is much better than I can get even if I use the toolpost grinder, so I'm assured that I'm not going to eat up the glands. Plus, I get extra corrosion resistance that silver steel wouldn't have. May have been "overkill" but these rod...
