JS1 Water cooled barrel

Hello Derek.
Sorry to be so long in answering your question re, weld of transfer boxes. No, the boxes were all brazed piece by piece. I found by useing the coolest flame possible to melt the brass the 20 gauge did not distort, once the brass has melted and solidifies it will not melt unless you are to use a very high flame like a cutting torch to apply the boxes to the barrel. First the barrel was preheated
both boxes then brazed on after which covered with old sacks ( not socks as Mrs Eggs typed) and allowed to cool very slowly about
2 days.
The cooling process for the engine worked extremely well, the process for the barrel cooling I've explained, as far as pictures,
I don't know how to do it and practice day, thats up to Brian but I hope we will be there.
