I always thought that this wasn't done, because the screw would likely blow out, unless it's perfectly aligned.
I'm wondering if there's a name for this technique (using screws to reinforce a butt joint), and if there's a jig or technique for drilling the holes?
For example, cross-sectional view:
screw __ _______________ [\\\\\\> ---> | | |_______________ board 2 | | | | board 1
I saw some guy doing this by hand (with no jig or drill press) in the second half of this video. Seems a little risky. Is this common?
I've found something called a doweling jig, seems like it would work if used on
board 2, but I don't think it would hold them both in place.
