I finally got my Harley Davidson Tribute finished today. It's been sitting in my workshop gathering dust for about a month, so i decided to finish it. The chamber is 24 inches of 4 inch PVc, bnut it also has the 4 inch wye. The barrel is 2 feet of 2 inch, for about a 3:1 ratio. i haven't fired it yet because it's still drying after the glue. I can tell you one thing though, it is a BEAST to hold. my arms are 37 inches long and i have a problem holding it. I have to rest it on a stand to get the ignitor. I initially had a problem soldering the wire to the sparkplug, so I got out the old torch and used copper solder to attach the wires, along with ghettolicious electric tape. The quick vent allows for a propane meter to be attached, and to vent it using the compressor. In all this project cost me about 150 bucks, more than I intended but i totally love the way it came out. Lemme know what you think of it.
