Good work Al I like the way you have done the tank block mounting to the gun.

Putting your job before your hobbies, Al? LOL!

Glad I got my part time employer to let me work just 5 hour days!

Nice work, as always, Al.... Where is the seal achieved between the removable stub that fits into the tube and the block?.... What size threads are you using?.... The ones I built previously used a through bolt and two O-rings.... one either side of the threaded ferrule....



With your one-piece stub, and the ferrule over it, I assume there is an O-ring between the shoulder on the stub and the tank block?.... Is the groove for the O-ring in the block, around the female threads?.... or in the shoulder of the stub, around the male threads?....

Rob M:
awesome work as always .. what seals the small threaded hole up top ? ( the small 1/4-20 looking one )

rsterne:
Rob, I think that is a blind hole just to hold the tank block into the jig for machining.... Al will correct me if I'm wrong....
