Yeah, I did get that. I forget sometimes that not everyone has access to a lathe. With a lathe it would be easy to do it my way. Adding seals is not really an issue either. ((again- if you have a lathe)access to industrial seal suppliers is also a bonus :D )

Regardless, kudos to you for thinking off the beaten path, this may well be the piston everyone is using next year!!

A possible further improvement of this design would eliminate pilot volume completely by using a latch trigger as I had done with this project:
