bingo!

i'm not sure about how large the holes need to be, but i think it's larger than the bulkhead by a bit (obviously) like a 2" hole for a 1.5" pipe, which really, is only 1/4" of play before you tighten it. and yes, I run a mag12 on 3/4" pipe and i'm changing it whenever I remember to stop at a store for some pvc...i'm pretty lazy when it comes to that
