A Pneumatic Horizontal Bandsaw Feedrate Limiter

[Okapi]

A good idea for people who hasn't access to a Festo store, inexpensive and perfect for occasional use.
Making sometimes such regulators for a more durable use when you doesn't have any air loss, as you make it with a long threaded metal part, you can make a more sophisticated end at your screw with a O-ring which gave a better sealing, as I have a lot of cut small parts, the use of square aluminium(and 4 jaws chucks on my lathes) permit to screw the part on the construction, turned with eccentricity as yours.

If I understand correctly, the O ring goes on the end of the screw to give a tighter seal when closed. I can see where that would work nicely but it might cause another problem. When the screw is backed off a little, air flows in the threads. The longer the distance in the threads, the more resistance. With that O ring at the end, how does air get into the threads?
