Riku, It sure sounds like you need more hammer weight or more spring . Surely youll have it worked out . I shared a couple PMs with Knifemaker and he told me hes been running with no valve spring for some time . Im going to give it a try next time out to see if I cant gain a bit of power that way also .

How does this concept work? How about the dual hammer spring mod? Excellent work, BTW. I'm quite new into the PCP world, so I can't even imagine how to do a conversion yet. Although if I get a Sumatra .25, I may look into converting it into a .357.

I wonder why in the world some refuse to ship to Canada. They do know that Canada has regular mail service. Yes? Odd!!!!I spoke to the station master at the unit in Temple Texas, and he said there was no issue with Airgun anything. None. and that anyone saying different is ignorant of the Laws and Regulations. Just flat strange!I too use solid valve stems. to prevent blow by, simply put an o ring on the stem in the valve body. The pressure will force it against the wall on the high pressure side preventing blow by. Knife
