Maybe I'm missing something, but if you drill the pips all the way through, won't you just wind up with a hollow cube... 6 drilled through will have 6 holes on both sides- you lose the 1, the 5 side will have 5 holes through and you lose the 2, the 4 side will have 4 holes all the way through and you lose the 3... ???? What am I missing???? I understand Mack's suggestion and if you drill 1/2 way, then you'll retain all the pips.
