Greg,
I'm a gessin that that's the one with the piston made out of 100 y/o cast iron.
It comes out of 100 y/o timber window frames.
They're from the cast iron counterweights that the rope connects to so when you open them they stay in the same position you left them.
It's good stuff and all you need to do is keep running it like you have been.
As the Arch-Bishop said to the Actress, have patience and it'll all be ok, .
Yep mate,
That's the one.
Patience hmm..... any idea of a supplier?
Not much of that round here.[&o]
It sounds very spectacular in the back yard even on an 8X6. I'm guessing once it's run in it'll be a good performer.
