Yes, I am more carefull now but at that stage the flame was frequently going out so it was not unusual for the model to just stop. The problem was a build up of hot oxygen starved air beneath the deck, at a certain point it snuffed out the flame. Curiously this never happened when stationary as the hot air came out of the ventilators but on the move fresh air was being forced down the ventilators until an equilibrium was found and eventually the flame went out!

It took a while to work out what was going wrong and to solve it. The boiler has a lagging of fireproof cloth followed by two layers of mahogany planks for extra insulation.

Despite an all up weight of 35 lbs I get 25/30 mins good steaming from the mark one bolier and its very consistent.

Canopus,
You have just confirmed what I have been banging  on about ,without all the GIZMOS you worked out what the problem was, if you had had all these extras on board, which I assume you had not, it would have taken you so much longer to find out what wasn't operating properly.
This is why I say to Newcomers get your steam plants up and running and then if you wish get all the extras once you have gained the experience of running a steam plant.

I have a steam tug CERVIA which has a burner made from a plumbers blow lamp head fixed with a swan neck to a gas tank and can get about 4 hrs running time with this and a boiler feed pump.
The boat weighs 35 lbs just like yours, this boat is 40 years old and started out with an electric drive , was converted 20 years ago to steam and to date have never used any of the boiler and gas control extras.
The D10 in the background is the new engine ready to be installed once the feed pump has been finished, with the original 10V in the back ground.






Thank's for sharing.
George.

Good to see another supplier getting in to making more steam bits and pieces, I have been corresponding with Jerry for a while now waiting for him to finish developing these and have put in my order tonight. For those of you wanting instant answers to emailed questions or orders though, be aware that he is away until Friday so you are unlikely to get an immediate reply. Cheers, Ian.
