Hi all,

very new to this and would like some help please if possible. I have recently bought a Stuart Turner No.9 from auction which looked very good, well built etc. I tried in on air and although no air was escaping, nothing happened. I took off the valve chest cover to find there was no valve, the rod is there but with no slide valve, it is not going to work. I have bought a slide valve casting but do not have the No.9 drawings to help me machine the it. Does anyone have the drawing of the slide valve they could email me. Would be very helpful.

Hi Andrew,

Strange no air was escaping if the slide valve was missing. I'd expect a major air-flow from the exhaust. Have you checked the steam passages?

Hi John,

sorry not being specific, yes plenty of air coming from the exhaust port but almost none for anywhere else (seals) is what i should have said. I have managed to get hold of the drawings now for the No.9 so will crack on and make it from the casting I have. Thanks for your input.
