3" Hunslet "ELIDIR" Safety Valves

Does anyone have detail drawings of "POP" or semi pop safety valves that I could adapt to fit my Hunslet. I am using the straightforward ball/spring valves at the moment as per the Reeves drawings but would like to improve the action.

Peter,
I can recommend Gordon Smith's designs. He wrote an article for Engineering in Miniature in February, March and April 2001. You will find a summary of these articles on the Leyland SME website at
http://www.leylandsme.co.uk/svalves.htm.
He provided me with a design for my 71/4 Ivatt Cass 2T which seems to work very well on air - not yet tested on steam. The latest e-mail address I have for Gordon is gordonssafetyvalves@gmail.com.

I hope this helps, Trevor Collyer.
