This short video denonstrates how the governor linkage controls the early cutoff.  You must imagine that when the red latch contacts the orange knockoff pin it lifts out of the connection with the gray valve control arm allowing the dashpot to close the valve.  Although these parts are extremely small, I believe they could be produced from cast iron or brass or mild steel.  My preference would be cast iron.

Hi Kim

Are you using the Harris Say Brite Tin/Silver solder?
They recommend using the Say Clean liquid flux with steel and stainless steel because it has better oxide removal. Also did you thoroughly clean both parts before assembly? I'm sure that you did but just thought that I would ask.
It also appears that for the color of the steel your heat may be been a little to high.

Just some thoughts,

First time the whole story on its own feet.
Next step will be to transfer the hole pattern to the round support and make the 3 time M6 threads each side.
If this is done, I can remove the center pin and the hole will be ready to receive a M10 thread rod for general clamping.

Yes - I use high temp silver solder on stainless all the time, its the low temp soft solders that dont work well on stainless. The Tenacity 5 is great, as is the Harris Black flux which is also longer lasting.

Osmaston Road museum has gone. The engines have been taken inside the company and scattered to various places for storage.

As for the piston engines, they are the wrong shape.

It would seem that the modern generation of RR senior management either don't read much or don't care.
