A little bit of background:
I am a member of Saltwell park model boat club Gateshead UK
The model started life as a Wide a Wake but changed along the way,it is a lapstake hull so called in the USA clinker in the UK.
With an overall length of 52" and a beam of 16" its a bit of a lump not sure about the weight but it hurts.
I have used a range of timber including: cherry ,pear, walnut and mahogony.
The boiler and pump followed the building of the engine, at the moment a modified camping stove provides the heat.
I have started to look at the gas supply side of the project including making an Attenuator based on a design by Malcolm from the Paddle ducks forum.
