^i totally agree with you. i just put little ones at the beginning and end of my rail, if i had those big supports i prolly woulda been fucked a couple times.
yea, thats the first thing i thought of when i saw it haha. it would be kinda sick to put plywood over the gaps between the supports (the part thats diagonal) to make it so you could hit if from the side sort of skateboard style haha
how did you attatch the PVC onto the 2x4? the only way we could think to do it was drill a hole big enough in the top of the pipe to be able to get the head of the screw though and periodically do that along the pipe.
