Gentlemen
I am proposing to build a gauge 3 model of a small 1900 bagnal steam loco. The original is small - 12' long and 6' high - cute!
It will be steam powered and have and have a marine type boiler - the combustion chamber is a larger tube offset from the main barrel - and it seems to me that this design lends itsef to a pair of cast bronze plates front and rear - would save a lot of work and look good
If the plates were sufficiently thick,and provided with a deep flange and subsequently silver soldered together would this be safe/ practical/ permissable etc.
Boiler to operate at 80 psi with a 160 psi test pressure
What is the view. Is cast material acceptable in a pressure vessle like this? If not why not? Or has it got to be bashed plates?
