Here are some items I'm thinning out of the collection. I will ship to Europe and elsewhere. https://www.ebay.com/itm/264357138758 https://www.ebay.com/itm/264357145270 https://www.ebay.com/itm/264357153106 https://www.ebay.com/itm/264357164918 https://www.ebay.com/itm/264357190825 https://www.ebay....

Your friendly ratchet strap.

The utility industry has other means of squeezing maximum economy out of a boiler system, but that is another story.

Fred, When you have time I would be curious as to what that method is beyond feedheaters.

flared funnels (tapering from small to large - base to top) seems alot of traction engines, wagons etc seem to have them..? I think the reason they did that is they were puffers exhausting up the stack. The engine exhaust went through a smaller nozzle aimed upwards, the flared stack created like a ...

Is there a way to work out how much draft you can get through the tube passage and proportion the ash pan door, grate and funnel accordingly? Yes, there are formulae for just about anything on a small steam plant, but my experience has been, experimentation is the only method that provides a truly ...

Not sure if it was intentional or not, but I calculated the heating surface of your tubes and it works out to 31.416 sq ft which is 10 X pi. Weird coincidence. Quoted: 1. economizer (Yes the more the merrier, as long as it isn't interfering with steam generation) 2. skin the smoke box & funnel (Abso...

They've held up just fine, but they are a bit finicky. The steam/water going to the steam side needs to be very clean. The O-rings on the piston and valve rods need to be high durometer neoprene. Have to lubricate this pump with a good reliable displacement oiler, can't run O-rings and rely on satur...

As simply a testimonial rather than suggestion, mine is very close to the hull and it hasn't caused any problems. The RPM we typically run and the amount of thrust we're working with, we can get away with a lot.

Not all whistles are created equally, sounds as though you have one designed for low pressure, or someone has been playing with it. They are designed for a designated pressure range, the gap between the languid plate and the shell dictates the pressure in which they will tone at the right frequency,...

".....the steampump/middle trycock level control that i have, it works but it's wasteful. " Sidetracking the original thread for a moment, I have also used the middle trycock level control, and it works very well. The trycock orifice is adjusted to let down full feed pump mass flow (liquid saturate...
