Ok, I'll try the copper air tube fabrication since I have the copper and see how it goes. Couple other points I'd like to ask about:
- Is the piston warping on the edge (1) a problem? I'm not sure if, once the spring releases, that edge expands to fully seal?
- In the image below, I have this piece of solid tube that sits snugly inside the pullback. It is longer than the wooden dowel used to reinforce the legs. Is there any reason I should trim mine down? Is that gap (2) enough room, or will some component need more clearance between the legs?
- And lastly, Am I comprehending the action correctly here (3). When cocked, the spring is compressed, the piston and air tube are drawn back far enough for a single bb to fall into the barrel (but not so far that the air tube actually leaves the barrel). I assume the air tube remains seated at the very end of the barrel so when fired, the air tube hits the bb while the piston also applies additional force by compressing the air in front of it and sends that through the little notch in the air tube accelerating the bb fully.
