Looking at this picture, made me think!
What is the required pressure this spring, so they do not move during the test, anyone know?

Thats always been a bit touch and go. If you make it to tight you load up the dial indicator to much. I have since that photo placed a actual light valve spring on the opposing valve to stop it from pulling open but I still use my free hand to make sure the opening valve is seated againts the dial so lightly.

I had little interest in it so it was put on the back-burner to get finalized.

I've been working on getting tooled up to build them in my shop, still have some fixtures to build to ease production.

I'm guessing I should get my ass in gear with it as once they are made I'm sure the market would be there. :)

Actually started machining parts for a small run of these . . . then all Hell broke loose on Flowbench parts right after the USA elections and I'm playing catchup now after the holiday.

I'll get back on machining parts for this project very soon . . .
