Ask me an easier one JB! I set off with the best of intentions. EoM has a larger stablemate which also needs flexible steam pipes:
The original burners in the Accucraft NGG16s weren’t quite as reliable as they might have been, and had a tendency to overheat residual steam oil in the smokebox, which then dripped onto the flexible steam pipes below and, er, burned through them. Result - clouds of unexpected steam and a failed loco. How do I know? I replaced mine with new heat resistant PTFE pipes designed for 3D printers:
The PTFE works a treat in the Garratt (although the ultimate solution was to change the gas jets and use stainless steel mesh to create a fully effective pair of burners). So I thought this would be ideal solution for EoM. Until I tried to connect the PTFE to the stainless steel superheater tube at one end and the cylinder block at the other. There was enough flex, but I couldn’t find a way to secure the cylinder end reliably. So I admitted defeat and ordered a pair of flexible steam pipes with pre fitted connectors from Roundhouse. I know, I know, I could have said that at the beginning, but I did try to come up with my own solution……
