To promote excelent contact between burner bell and lipstick tube can the be threaded?
I don’t see why not. After being heated to burner temperature and then cooling off, it might be difficult to take apart.
Extra process at the factory, extra material needed on parts. ?
NOT a good idea.
They fit so tightly that you can have problem taking them apart without threads, threads can only make things worse.
Or you could make them in steel like the Army No.2 Mk2. Not strictly a lipstick but as near as dammit, and the buggers always come apart
Certainly the threads on the vapouriser couldn’t be cut in the thin steel of a conventional lipstick vapouriser.
Alec’s referring to this arrangement - two of each component here because they’re from my No.3 stove (double burner No.2).
A crucial point here is that the mass of metal in a No.2/3 burner requires the volatility of gasoline to sustain vapourisation. Double priming, or use of a blowtorch to prime, can get kerosene to vapourise, but only for a short while.
A Primus 107’s burner dodges the collapsible stoves’ (‘96’, ‘100’) conundrum by having the burner bell permanently attached to the vapouriser component.
Those photos of the barrel nipples with the jet in the end is pretty much what i had in mind.
I have a 316l 1/8 bsp nipple and a brass end cap.
I may have to make the barrel from brass-actually more fun that way.
I also used your tutorial on hypodermic needles.
I can get .5mm lpg screw in jets by the bucket load for $4 a piece.
I ream it with a .5mm drill and press the needle in and sand with 400grit w&d paper.
Better thermal conductivity too.
