Sorry for such a long wait for answers, in my quest I have dug into other topics and got side tracked.
No this will not be a wrap around, but I never thought of doing the plans that way.... great Idea, I will reply once I get my PVC pipe.
Yes PVC is cheaper plast and does not weather well. What you can do is paint it with an engine enamel. This will give it a good chance against the elements.
This will take a while for me as I only get a chance on every second weekend to play around with my own projects. My wife owns me every other weekend.
