Hahahaha you'll get it buddy, just slow down a little and things will start to make sense. After all this your going to be a heck of a DIY'er .
Get a 1/2-3/4" length screw like you might get in a doorknob kit. I always add a dab of silicone when i sink them into PVC too. Do it slowly and don't over tighten and strip it.
