Got the boiler steamed today and I’m pleased with how it went. The attached video shows the safety valve keeping the boiler pressure at the working pressure of 40psi. The engine operates well on the reverse valve although there is still some leakage through the piston valves. The reverse valve is still performing well with the O rings providing a good seal in the off position. The valve is slightly tight but the servo manages to push it most of the time. Sometimes going from off to the forward position it doesn’t move but going into reverse and then switching to forward it gets there OK. The boiler can keep up with the engine steam consumption at part speed but not at full speed when under no load. Hopefully when the prop is loaded in water, the reduced speed will mean the boiler keeps up at full power.

Next task is to steam it in the bath and see how it performs.

Make your own contribution to the Website

We welcome well written contributions from Website members on almost any aspect of Model Boating with a particular emphasis on practical hints, tips, experience and builds.

In order to maintain a consistent standard and format, all suggestions should first be sent to me by Personal Message for approval in principle. Only a very limited amount of time is available for editing contributions into a suitable format for placing on the website so it is important that the material is well presented, lucid and free from obvious spelling errors. I think it goes without saying that contributions should be illustrated by appropriate photos. I shall be happy to give advice on this.

The Member Contribution area offers space for short informative mini articles which would not normally find a place in Model Boats magazine. It is an opportunity for Website Members to freely share their  expertise and experience but I am afraid that virtue is its own reward as there is no budget to offer more material recompense!

I look forward to receiving your suggestions.

Colin Bishop - Website Editor
