HI Stuart,
The cylinder was turned from 3/4" Brass square and it is the exhaust port you can see on the top. The steam chest goes on the flat face towards the top of the picture, on the side of the cylinder. Very frustrating weekend - breaking a total of three taps as I was starting to assemble on the base plate. Anyone know a way of removing a 10BA tap in 6mm steel?
The Argus name plate that Graziano has done is for my first engine - the oscillator shown a few posts ago, and will be attached to the jarrah base it is on.
Pete
