Hi,
I just found this interesting thread. This boiler design looks really interesting. The book mentioned in the first post, MODEL BOILERS AND BOILER MAKING by K.N.HARRIS, does this include instructions on the calculations required to design and produce such a boiler?

Thanks

Ian

Ian, The book contains formula for calculating the strength of matirials, and the constrution of meany boilers but not the "Wedge" boiler. It taught me enough to build my own.  Geoff

Will be replacing the insulation on this boiler. See the Duke of Devonshire thread. R.G.Y.

I am lighting up the boiler at last. Please all you knowledgeable people who have offered advice in the past. Go to construction Duke of Devonshire. I would value your input. R.G.Y.
