im wondering if i could do this with a 4 inch tube and whit bigger wood. i cut at 4 and 8. im thinking i could do the same thing and then put the bigger piece of wood up higher and support it
I'm sure that it would work. But possibly a cheaper way would be to attach a 2x2 centered on top of a 2x4 to form sort of an inverted T looking thing, if that makes sense.
It could and probably would, but it seems a little bit wobbly, If I were you I would just put some scews on the side so it does not wobble..the pvc part.
