Ompa: I noticed you used 1u1/4" PVC for your pressure chamber. I was wondering if you could tell me what #O-ring you used on the head of your plunger. I've been having some trouble find the right one.

Thanks much,
FH

If I was at home, where I still have the bags, I'd tell you right away. As luck would have it, I'm at college right now... I personally just went to the hardware store and started trying out o-rings. If you find one just a bit smaller, cutting the grooves in the plunger head so the o-ring fits tight around it should increase the circumference by a little bit by stretching the o-ring, making a tight fit.

Ronster, around 7-8 per mag at the moment.

General Cole, as of now, I don't even know where the nearest hardware store is, as for the past week I've been moving into/adjusting to college life. Hence my lack of presence on these boards.

Shadow, I just have terrible luck with finding springs. I've been to all the hardware stores in my knowledge around my hometown area (when I made the rifle), and couldn't find any springs that would have worked; they were either too strong, or the diameter of the spring wasn't big enough to work properly in the gun.

Assuming calc and physics don't end up giving me hellish amounts of homework, I should be back to active status on the boards within the next week or two...
