Notes

One frame for all three rolling-diaphragm engines: the 2 in cup hangs from a spool hanger bolted to the wall, its closed end 40 mm over the torch stand's ring.
The wall has a window behind the hot end and the optional finned cooler, so the fins clear it and the flame has air.
The base reaches 300 mm toward +X, under the power head and flywheel on the tee's branch.

Which engines use it?

The rolling-diaphragm beta, Ringbom and gamma: they share the cup, the hanger height and the torch position.
