spudshot, how does that barrel work out for you? i was just wondering because i built something similar out of galvanized steel, the barrel is 30" long and it has a large ridge down the side of it that stops anything tight fitting from going down. i just went to home depot today, and checked all of the 1/2" metal pipes, and they all had that same ridge. i just decided to use a sch 40 1/2" barrel, but i was wondering if you had this same problem.
in the upcoming presidential election, there will be several candidates who will be running, one of whom is Hillary Clinton. Now WAIT A SECOND!!! I though there was some sort of rule that prevented someone from serving more than two terms in office. Vote Against Hillary: Presidential Elections 08
