Whitwell Steam Rally 8&9 June 2013

Ingenious use of several pieces of steam machinery. I'm puzzled by the fact that there is 'no regulator between boiler and engine'. Is there some other sort of stop valve or how do you stop the engine from running whenever there is pressure in the boiler?

There is a steam stop valve on top of the boiler. When driving it is easy to let the Pickering governor do its job and just use the gearbox as the top speed in top gear is only 4 or 5mph. It may be possible to adapt a ball valve to act as a regulator and do away with the governor but the design is still evolving and that may be something to look at in the future. It has a bracket that fits on the front to carry a dynamo thereby converting it into a 'showmans dumper! ' I did suggest to David that he put some twisted brass on the roof supports but this idea received a distinct lack of enthusiasm, in fact an emphatic NO.
