Traction Engine. New Parts.
by John
Another quickie.
The new safety valves arrived today. Warrick Sandberg valves. I will install them later this week, and fire up the Fowler R3.
The old safety valves. Not up to the job.
The new safety valves. about the same dimensions but the exit holes are bigger and the spring tension is adjustable and lockable.
And another thing. I noticed this label near the pressure gauge of the full size Fowler R3.
So I made this one today. Slightly modified the information to suit my 3″ scale Fowler.
My enamelling technique could improve, but it will do.

Thank you. CNC milled. First occasion that I have tried the raised letters on a painted background. A bit tricky milling such tiny letters and keeping them sharp and intact. They are only 2.5mm high.

Good work John, don’t worry about the enamelling, gives it some character.
