I decided to change the wheels on one of my Mamod based locomotives. So some cast iron wheels that I have had for a long time were turned and Mamod crank pins fitted to them. Having fitted the wheels I decided to make and fit an exhaust regulator; I haven't made one for many years and the ones made were basically the same as a conventional regulator. The all metal ones made were always difficult to fit into a smoke box and connect pipes to. For sometime I have been thinking of a slightly different approach. This is the result.
The parts.
The assembled working bit.
What it looks like in the smoke box.
The operating valve options.
Testing with air.
The model completely assembled.
The exhaust regulator certainly works as well as the all metal ones that I have made and is a lot easier to fit.
Exhaust regulators are very sensitive and work very well allowing slow powerful running.
It has been run on steam but alas the weather doesn't allow a proper test on the garden railway.
I have made a video of the steam bench test and I will post it when it has been down loaded.
Regards Tony.
