That's a fundamental question, I'm sure. I drilled a 3/8" hole and hammered a 3/8 bolt through, but it was tough. Can I just drill a 1/2" hole and put the bolt through that, using a washer on the nut side? Or would that be too loose and defeat the purpose?
For context, this is for the construction of a 4' x 4' x 8' QT. Thanks!
