What I was driving at in my earler thread was the simple fact, that there is no set procedure for boiler design in the UK. Martyn Evans, Jim Ewins, Keith Wilson all seemed to use slightly different calculations, maybe they all come out in the same ball park area, but non the less different. Just thought if there was some easy to follow log book that was filled in covering every thing from materials to design and construction, so at the end of the build the owner has a standard record. On materials am I right in assuming deoxigenated copper should be used for boilers? What types of bronze are okay for bushes. Again if all this was stated people would know exactly what was required. Do Austrailian codes cover the above thoughts, if they do then it's a fair proposition to perhaps have something along similar lines. All i'm thinking of is uniformity, and also making the boiler inspectors life easier. As to construction the log book could also have signatures from the boiler inspector at various stages of construction, again I believe this is something most clubs do.

Hi maninshed As I mentioned above please do yourself a favour and get a copy of Australian AMBSC code and find that it covers everything you mentioned and much much more .It is good reading and information on boilers for all models including traction engines where the boiler is the frame .If that is not enough there is a code for steel boilers and one for the HO 's .

G'day all
I count it a privilege to jump in after Shawki.
I am a professional engineer, not mechanical, and new to muddle (sic) engineering. As an engineer I am used to interpreting codes and over the years have learned much from them, as much as from other sources. I am attempting to turn copper pipe into boilers and not scrap so I have purchased two of the AMBSC codes Shawki mentioned. I found the codes incredibly informative such that I am sure that I can design a boiler which will pass inspection. All the data you need can be extrapolated from the code like plate thickness, bending radii, fillet depths, stay spacing and stay diameter and joint methods.
The design will be safe if built to the code. Not only that the code gives you comeback against the boiler inspector should it come to that. It may not steam efficiently, but that is another matter.
My skills may not match that task, that is another matter.
Regarding the "driving license", I don't have one (yet) so you might expect me to be in the crowd which decries their value. I endorse the concept where public running in involved or where there is more than one "loco in steam". In a public place you need to have drivers who a club knows can operate locos safely and reliably. You don't want run-in accidents due to braking or derailments due to unsafe speed. You don't want delays due to failing to keep steam up or loss of water.
I have the notorious Ozzie aversion to red tape but there are some things like the AMBS codes and the driving license I support. Self regulation by the body keeps the bureaucrats at bay.
Regards Ian
