NICE !!! .... I especially like the controlled flame positioning system, as that seems really critical to get the best out of a vacuum engine.
Thanks Daniel, I reckon James came up with a very clever method with that system of flame control.
I only have one flame licker, a Solar Engines #3, and it is a dandy, but I find positioning of the flame relative to the port is hyper critical for good performance, and mine offers nothing in the way of precision adjustment, such as does your Maiwald.
I may have to look into this issue and see what I can adapt that might offer an improvement along those lines!?!?
Daniel, I'm pretty sure it was Rog who worked out a way with his Solar Engines #3 by putting some of that thin magnet (fridge magnet) on the bottom of hie burner so that it wouldn't move around.
