depends if you actually drill through the pipe, or jsut stick them inside, i would use epoxy if you are going to be putting holes in a pressure vessel

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
