Having finished the bulk of the build on my steam launch it was time to sort out the gas supply.
I came across a book by Stan Bray and noticed a design for an attenuator and gas regulator by Malcolm Break.
Using the download and the book I was able to make some progress however due to a number of errors in the book and unclear photos on the download I was a bit stuck.
Malcolm to the rescue he provided some helpful information and photos which clarified the design, some a big thank you to a fellow Paddler.
So far so good I still need to locate the pipe inlet and outled pipes and source some suitable synthetic rubber.
