Hey guys check it out going to build these racks within the next month or so. 4 sheets of xpvc "tyvek" is going to make 2 3 bin 41qts and 1 60 bin 5qt tub for hatchlings. Its about time I expand my capacity any suggestions greatly apriciated. Also has anyone used pvc glue to bond the sheets together instead of using screws. The last rack I built of xpvc didnt take screws very well after a while the rack was unusable.
