Ideally, the piston should slide backwards to expose the complete diameter opening to the chamber side of the T.
If you can stop bounce the final piston position will be wide open.
Today was the first time that I succeeded in opening and stopping the piston in the optimum position.
An added benefit is that when slammed open, the piston seals the pilot preventing further air loss.
What a BLAST difference a wide open valve makes!
It is like I have made a new gun.
It took a lot of trimming and shaping on the rear of the piston plus I had to design a completely different shock absorber and piston retainer.
I wish BTB would write an ode to the Trom-Boyn.
Since you can't blue copper, the song cannot be the Blues.
