I've been taking "stirring" lessons here.

Anyway it appears to be paying off... I added photos of fluidyne engine
work from folks aound the world to my web site and, because a few of the
folks here have shown some interest, I thought I'd post a "heads-up".

The second engine by Simon Popy (France) even incorporates a bit of
woodworking.
