"Rex Grigg" Bubble Counter & Fabco valve - Panel mounted w/simple vernier mod
Nothing to do -- Waiting for my plants -- bored out of my skull so I did this ...
That's a Rex Grigg's bubble counter with the Fabco Needle valve. I did a quick vernier design in AutoCad that gives 100 repeatable divisions per turn and now I have 900 repeatable steps for a 9 turn valve. This way when I find a regulator pressure and needle valve setting that works, I can still experiment and get back close to the staring point with a minimum of trial and error.
