Wayne, a thought about the 18" PVC. I posted something in the "molds" section about this a week or so ago. You might check with your local public utilities (think waterworks) dept. They often have off-cuts and stuff like that and are more than happy to have you take away a piece (makes for good public-relations). I can get up to about 18" here and I live in a small town. Just a thought. bill
