Re: Old video on a Steam Tug

That tug boat engine has four cranks! It appears to be a double compound to me, with the LP cylinders in between the HP's. Anyway, that is a big tug boat to sport an engine like that. I wonder if the wheel house is a set. No window frames?

Re: Re-using oil

A quart of oil in 4-8 hours seems like an awful lot. I probably use about 2/3 of a cup, if that in a day's running. To each his own!

"It Seems to me that the lifespan of these modern boilers is getting less . Her original double ended scotch boiler lasted 34 years wheras the last 2 sets only lasted 19 years each. " I wonder how this could happen. There was a thread on the Railway Preservation Interchange several years back that ...

Re: British Rivet Manufacturers?

They are for use in repairing riveted boilers, and no commercially available US made rivets are suitable for boiler work. British boilermakers are doing enough riveted work that I would like to think that there is someone is mass producing boiler rivets. If I can find them and cross reference the al...

British Rivet Manufacturers?

At the 10:00 minute mark in this video, Fred Dibnah visited the Boulton Rivet Manufacturing Co. I am unable to find this company on line. Where do British boilermakers get their steel rivets in 2019?

Re: Prop shaft diameter ?

What diameter is your crank shaft? My boat is 23' long, weighs 3,000 lb., has a 6 plus hp engine, and a 1" stainless steel shaft, and is perfectly happy. My last boat is 20' long, weighs 1,200 lb., has a 2 hp engine, and a 1-1/4" hollow brass shaft about 6' long which would buckle under full steam u...

Re: Funnel Diameter to Grate Area ratio

However, the question for today is whether there is a rule of thumb out there for stack internal diameter against grate area. One would assume that our ancestors would have worked that out. Indeed they had, but your question is worded to ask for a comparison between apples and oranges. The question...

Re: Valve Material Identification

Are you sure that your local hardware store doesn't offer replacements? My local True Value has a number of bins of replacement valve discs. It doesn't have the grain texture of Tufnol and is very brittle. Taking a bite at it, it has the feeling of a ceramic rather than baked fibre. Is that a clue? ...
