Okay...I'm planning to go and make a couple homemade nerf guns and start a small Nerfing group. I also need to make a couple sets of stefan darts for these guns.

The homemade I'm planning to start on is a variation of the Ball Valve gun on this site, instead of having a breech (too hard to make right now), I'll put in a 1" PVC to 1/2" PVC converter right after the ball valve (because I don't want to make the whole thing out of 1/2" PVC as I would like a larger air tank (out of 1" PVC).

Now, I was wondering. do any you have any tips on how to make such a gun (I plan on making about 2-4 of them)

Also, what size foam backer rod would fit in a regular modded gun (after this, I plan on getting one or two NFs and an Uruk-Hai Xbow to mod.) and what size would fit in the 1/2" PVC I plan on using?

Thanks in advance for your help.
