And..... Here's the burner, that was
coming on, a couple of weeks ago!

Usual build. Top of a salt grinder/ pot.
Brass disc, base, with central locating bar, and supporting foot underneath the wicktube.......

The crossbar locates nicely, in the rim of the bowl/ firebox.......

Until, my fumbly fingers knocked the burner, fully inside the firebox!

The only way to retrieve, was to lift the hot engine, while it was running.

A taller, breather tube, stopped
that happening again.........

Here's another,
final video........
Job's a good un!
