wonder how that project will end up for you dd...you sure don't waste any time...

Well, at least I've got a couple of models to look at.  Both the Primus No 5 and the later American made Vesuvius use a similar "technology."  The Primus has an internal baffle, but the Vesuvius does not.

At any rate, one trial result I didn't mention was that the decibels were cut by at least 2/3rds.

Time ... that's what retirement is for!  More time to tinker, more time to plan trips, more time to play with/develop maps.

BTW:  I'm still working on a home grown fire-piston ... something less bulky than the commercial model I have.
