Well nuts can't find the "plans" I used to make mine but did find the website I got the basic directions from.

I adjusted the lengths.
I believe we used 2 10' lengths of pvc for the frame,
then used a 3rd one for the clamps,
and I used what was left of the 3rdone to cut alternate side pieces for the frame, thus giving me more options for assembly.

I used 3/4 in pvc and it worked fine, also used the thin walled pvc for the clamps.
Cut them about 3'' long then cut one side of it to make an opening (cut the 3'' length stand it up on end and cut approx 3/4-1'' off one side) You can cut them shorter or longer but the 3'' seemed the easiest to cut with a hacksaw, so I wouldn't cut them much longer.
