I tried making the dome covers that Mel talks about in his new book(page 71). I bought some 10' 1/2" PVC tubing. Made a dome. Connected it at the top with a plastic thingy. I even had the great idea to make clips to use to attach the plastic sheeting!
We're at the plumbing stage in building our new home. So, I grabbed a small piece of pex tubing and cut some small pieces then cut them open with tin snips... this allowed me to create a "C" clip to go onto the 1/2" PVC.
Then I went to attach the plastic sheeting while the wind was whirling around me. Guess what? The whole dome thingy took off like a kite.
I'm thinking about drilling holes in the PVC at the base, then screwing the PVC to the box... I'm wondering if that will make it strong enough to stand up to this Wyoming wind????
I may even try the covered wagon style of cover (see page 76 in Mel's new book). But I think that the dome structure is the stronger structure... what are your thoughts?
