I have built one out of a piece of 12" diameter pipe that is 20" long and i used 4 way lug wrenches for legs. I used 1/4 " plate to cap the ends. I used a wrap around and took 1/4 of the circumfrence and left about 3 inches on each side and cut it out for my door. It works pretty good. I will take pictures of it next chance i get and post it.

This is what i am currently working on. it should look alot better after i get the paint/coating sandblasted off.
