I haven't made an instructable because I changed things up a bit. Mine has been holding up really well for over to a year now.
I welcome anyone that wants to collaborate on this because I never had the time to post an instructable. . So far I have added 3 people and will add anyone else that is interested.
"Lutherinski" has made one with electrical conduit and would like to post his pictures as well. maybe he will post an instructable?
