My new G250Vs and ramblings

[buddhasummer]

FTR never once had to flip the vane on any G250Vs I made and sold. Everyone would free flow, I only used .216 springs.

I don’t know what spring is in mine, but I have few 216, I’ll try one in the non free flowing one this morning.

That would be great. Hope this isn't a the way you're holding your tongue thing.

? Or should I just swap springs?

 

[buddhasummer]

Try spring first haha...

Just tried with a 216 spring no change still no free flow.

Experimented I unscrewed the adjustment knob a bit passed the removed retainer clip and it would free flow.

Yes, I too have noticed the variation, of cracking effort, if knob if all the way out or just a fraction in. Seems a fraction in nets best result.

I kept the clip out and went a little passed the stop.

Flip the vane around and still no free flow.

You guys are barking up the wrong tree. Both Dr. Rob and I have suggested the issue is with the lever as that is what separates the hard and soft seats. If you want to experiment, change one thing at a time in the same regulator under the same conditions.

For the record: I still believe the manuals that state for maximum flow the vane crescent should face the aspirator is incorrect. Look at the wording: "facing forward toward the back of the diaphragm" & "facing forward toward the mouthpiece." What sort of double-speak is that? Someone just made a typo or editing error and (just like in the aircraft manuals I've read over the years) the mistake was copied by the script writer.

Speaking of aircraft, if I were to ask you to design an airfoil with a crescent; would you put the crescent on the leading edge or trailing edge?
