Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

I found an extra PMR crowned bronze flywheel and installed it on a stuart #7. This engine is a little bigger and more powerfull than the PMR and runs well at half the PSI. It runs quite smoothly and will surely be able to make long runs at engine shows. I did have to go back to the shop to knurl the pump drive pulley. as the belt was slipping a little.
