Trevithick Dredger Engine. Almost There.
Firstly some pictures.



So, I have reassembled the engine and the burner and the base.
Did you notice the base?
No? Excellent. That is the idea. A nondescript matt black base which is barely noticed.
Yes? OK, well it must be OK.
Then a trial of the burner inside the firebox, using the changes which have evolved over the past few days.
During the video I am constantly changing the propane flow, and there is a clear “sweet spot” point where it looks really good, and feels very hot. I have not yet tried to steam with it.
