Thanks for your comments
i think they are fe's..nice gun but u should have built a pneumatic with those fe's
Yes thats fe´s we have many different types with or without flat bottoms.
yesterday i thought the same to built a pneumatic but now its too late.
I doesnt have to vent them because if i fill i open the ball valve and put the gas burner there. The gas burner mix the air/gas and simultaneous blow the old exhaust fumes get blow out throug the tube. That fill/vent process takes 20-30 seconds than one chamber is ready to load and fire.
Shure i will make a video but i dont know when because i haven´t a good location momentary. But at the latest on Silvester !
