Brit safety valves

[richardwilliams]

I need to renew the springs on my safety valves as I think the current ones are incorrect, the loco never seems to actually 'blow off'

Anyone any suggestions on what spring to buy as I cannot match those shown on the drawing with anything Bruce seems to sell (Bruce has a detailed table in their catalogue).

Bruce who?

HI Richard. When you say the engine never seems to blow off, what happens when you reach maximumn boiler pressure?

'everyone ducks behind the nearest wall'...............hope there is a more sensible answer to follow to that question!
