Re: Confirmation of Water Consumption

... Also, is it pressure related ? If I run at 80 psi versus 130 psi will I use less water ? thanks in advance for the help jon Yes, the lower the pressure, the more water you will use- steam engines are heat engines, the more pressure you have in the boiler, the more energy you put into the steam ...

Re: Confirmation of Water Consumption

I used 5 gal/hr as a working figure; seemed about right when I was non condensing.

Bring extra water. Delays happen.

Re: On the water testing of Folly

No picture but it is 3/4" copper (7/8" o.d.) about 5 1/2' long. Spaced out from the hull about three inches and about eight inches to one side of the keel. Extends from the mid point of the hull towards the rear. According to many recommendations this should be on the small side but, as I said, the...

Re: Nylon Prop Shaft Sleeves

I used a nylon sleeve w/ Otter's new prop - it works like a charm. Simple and easy.

Re: VFT boiler leak

When I was in the Netherlands in 2000 for "Dordt in Stoom" we rode on the Finland, a steam tug, from Rotterdam to Dordrecht. A few days before we were to set out the inspector arrived, and it was determined that a flue was leaking in the giant Scotch boiler. The boiler was still warm, but it was dra...

Re: TSP in the boiler water

I built Otter's boiler in 1996; I've always laid it up wet since the design makes getting the boiler completely dry time consuming. I live in an area that doesn't have hard freezes, so whenever I won't use Otter for a week or more I blow down completely and fill the boiler with water w/ TSP. This ha...

Re: Engine lubrication

There is certainly a lot of odd advice out there about lubrication. My dad and now I have been using ordinary motor oil on my South Bend lathe now for 66 years. Not for the head stock or apron but for all the various oil cups here and there including the ways. Still in first class shape. Even the o...

Re: Engine lubrication

Green Velvet, markets steam cylinder oils, compounded types for plants that do not need to separate the oil from the condensate. Their marine mineral oil separates readily in the hotwell (next to impossible with compounded steam cylinder oils) and has a tackifier to make it adhere to metal surfaces...

Re: Engine lubrication

I use 600W steam cylinder oil for laying up the engine; for bearings, con rod, eccentrics, etc. I use Vactra #2 or #4 way oil as it sticks, is readily available in 1 gallon quantities and is designed not to mix w/ water based coolants. The tricky oil to get is proper steam cylinder oil for condensin...

Re: Screens(mesh)

What one needs to realize is that a yacht finish, esp. with a steam power plant, is a labor of love... and that historically the vast majority of steam propelled craft were "rough and ready". I find that minor damage is much less obvious, and more easily repaired, with an oil finish rather than laye...
