Hello. Here's a short video of my steam tug on trial in the bathtub.
http://www.youtube.com/v/6wJSdGhEffo&hlI have finally added some lead ballast (lead sheet used for roofing) and now the tug floats deeper, as it should.
Been also working on the steam plant in the last few days: Added a valve to empty the condensed water from the oiler too, a useful thing to have.
But I'm still not happy with the burner, as it isn't very reliable and sometimes the tank won't feed the burner. It can also overflow if the valve is forgotten open or something else goes wrong (don't ask me how I know, the whole inside was on fire this afternoon, when the burner overflowed because I had forgotten to close a valve before refilling - luckily I had a biottle of water handy and no serious harm was done, except for a molten electrical wire).
The space in the hull is very cramped, so I'm considering using a simpler and more reliable burner. I'm thinking about using one with wicks and maybe 2 or 3 "mushroom-style" vaporisers. What else would you suggest?
