Man, I don't know, that looks like a real pain in the ass drilling, cutting and deburring all those holes, when 4 double Wye's glued on would not only be more solid, but would also give your arms a little upward slant to keep the yaks from slipping off. I mean, it didn't look to me from what I saw in the garage and the back yard that the financial burden of a trip to the hardware store and cost of 4 pvc fittings would break the bank, regardless of what was "sitting around".
