Hi Tug,
I have built many valves for steam and air control. I did a work in progress quite awhile back on some that I made. I'll try and find the thread for you.
I found it.

Any particular valves you are thinking of, I've made the Clack, blowdown and cylinder drain valves for my 2" traction engine. Bought the globe valves in but have made them in the past on teh 1" minnie in my avitar.

Few pics in this thread

Thanks for the pics. You make it look quit simple & you achieve a good result. I will have to have ago along these lines and see what happens

 

[tugwilson]

Thanks for the pictures of your valves etc. What an achievement!! I could not hope to match the superb quality of your work. Did you have any drawings for these valves to work too or didyou just make them as you went along so to speak?
Any way carry on with the good work I would love to see the finished engine.

I'd stick with nuts and nipples on the traction engine with bent pipe, the cast fittings are not right on an engine of this type, ideal for Hit & miss engines though.

That would depend entirely upon the country of origin, and unless I missed it I don't see an indication of wghere Tug is or what engine he's building. If the engine is British, such as an Allchin, Ransomes, Burrell, or Fowler, then nuts and nipples would be prototypical and appropriate, but if it's of American manufacture such as a Case or Keck then cast fittings are correct.

It is a Ruston Proctor SD Light, Haining's 2" design, I have exchanged several PMs with Tug so was basing my comment on that and hopefully he's now got some valve drawings to work to.
