Okay, will it matter if I cap up the other end? And you're sure it works, right? A cheap CPS would be great. I would need to drill a small hole in both ends.I designed a inner tube cps the other day, quite simple. It can use teh rf20 mechanism also, but fit a small section of 3/4"pvc on either side of the bladder, endcapping one side. Clamp both sides. The do whatever you want with the other side, wether attaching it to a coupler, or sanding down the rf20 mech and shoving it in there.
Doh, now I realize that you need that end piece on it. I don't think that would matter, right? I just didn't know that you could use it like that.
