| DavidA:
I meant for starting. Looks as if you have it covered. Dave. |

Thanks Dave, but you got me thinking. If instead of a stopcock it was a spring loaded pressure relief valve plumbed back into the steam outlet pipe, it would be automatic. I wonder if that would be better? I guess the stopcock might be better. Water locking on startup isn't the only reason you might want blow off steam. I've also thought about condensation in the crankcase. Maybe the steam line could run through the oil and the oil temp kept above 100C. Crankcase would best be lagged as well as the cylinder, then, I suppose. |

Snow is coming down and I'll have to start plowing shortly. But got the underside of the head milled and the bosses milled on top. |
| DavidF:
Snow Blah!! would rather roll in a pile of stainless swarf... |
| vtsteam:
11 to 19 inches predicted here, winds to 33 mph, wind chill -4F. And most of it at night, which means it will be drifted higher than the scraper blade by morning, and that makes it tough going. Guess I'll plow at dusk and let it go over night, see what the morning brings. We're lucky I guess -- somewhat north of the main track and force of the storm. I hear Boston is going to get hit big time. Well, plenty of wood stacked up, and the 6 hp Lister Diesel generator is ready to go. Probably won't be able to get in the shed for awhile, so no machining. Maybe filing is all I'll do. And think about how to do the valve. |
