new 9mm beastly build
started this the other day . 1/4 the way done an everythiung seems like it will be good .
27” 9mm barrel , .375” valve opening with two .26 inlet holes an .312” at the pellet end , with .700” open air around it . not sure what pressure i’ll use , but when i find a good spring i’ll figure it out .
had fun making the angled bottle connector , i made the bigger thread on a lathe , then clamped it in a vise with the top angled at about 15 deg’ . then used a bolt hole program set at 90 hole in 360 degrees . then just left the cutter down an advanced to each of the 90 numbers . it worked well after clearing the bulk away first .
hope to finish it soon .

made bushings, tube cap and breech fit to barrel.
All aired up for tomorrow and with luck will have somewhat to report 🙂
