Bake8c, what i did was drill a pilot hole, and then drove 2 screws in, but not all the way, then drove 1 screw in on the opposite side, i did drill this one in almost all the way, came back and tightened the other 2 then finished off by tightening the single on the opposite side. All while clamped tight between 2 scraps. Hope that helps! Good luck with your build.
