I have given the whole leaking boiler / expansion valve some more thought and realised that the expansion Valve is not the problem. The water was leaking directly from the boiler. Not being able to get up to my shed for the past two weeks i have been thinking the problem over and over and this morning i remembered that when I came to put the pipework back together there was a bit of confusion about which pipe connected to which port in the inlet manifold. I am guessing that I have the fill pipes mixed up so the manual fill port is connected to the autofill solenoid and the autofill pipe is running straight to the boiler with no valve to hold the pressure into the boiler. Thats my hope anyway. it makes me look a bit stupid but it is at least an easy fix
I also got the pattern for the new steam taps back from the CNC guys. it was just done in white plastic. The next job is to make a silicon mould and cast a couple up in black resin. I have also ordered some metal disks for the centres and these will need to be screen printed.
Its probably an unnecessary expense but I've always liked the look of those original tap handles and they will add something to the look of the machine.
I have put aside a day this weekend to hopefully get some work done on this machine. I will take some more progress pics
