So vaguely familiar some how
So after some thought, the gun came apart again and I popped a Huma regulator in the tube, so it is now a “double regulated” gun. I have the Huma set at 2200 psi, and the JSAR adjustable reg set at about 2400 psi (I’ll still play with that some as time goes on as it is so easy to do).
I'm curious about your decision to put the HUMA in. I get the concept of two regs, to take the strain off, and possibly also to minimize creep. Good stuff. - But here are negatives. First, obviously, you no longer have an external adjust for the final pressure. Second, you've made the plenum much smaller. The first issue isn't huge, if it's a 1-purpose gun, but (assuming you previously had the JSAR set to 2200) did you notice any performance decrease after the HUMA install?
Very nice build, Alan. Thx for some info on the dual reg set-up and results. I have been thinking of doing the same.
Yes indeed. Replacing that soft ball seat with a PEEK one really stabilizes the output.
