[quote=Basile;No , i've just got an idea, Lowes has pre-cut plexiglass that i can buy. Then i'll rebuild another support system with 1" pvc this time and still put eveything on a plexiglass who'll spread the total weight along its entire area of the panel and protecting the glass at the same time. Thanks for your inputs guys.

I would buy the thickest plexiglass available to have a safe piece of mind.
Make sure all your PVC on the bottom is as straight a possible simply to disperse the weight equally...
I like your design..
