Thanks for the comments. Yes, a wood handle is on the agenda.
I also used a 'gang' valve setup to run three KJ Miller engines
at the same time from a compressor. I added a you tube link.
This was taken by my wife on her cellphone and you can sort of
see the valves in the back when I adjust them. This was my first
video, and it shows.
I will be buying another valve that has a threaded end to see if
I can use it to make a more secure setup.
And, Raphael, you make some nice videos with excellent engines.
I studied French for 3 1/2 years in high school and was pretty
good at translation, but that was 52 years ago. Still, I pick
up enough here and there to understand what you are saying some
of the time.
