Over 1,400 color photos and drawings illustrate the methods, from simple butt joints to angled tenons and complex scarf joints. A project as simple as a box, for example, has a dozen ways to solve the joinery question. And, since many joints can be used interchangeably, Joinery leads you through making the right choice for your project based on the function of the piece, the time you have to work on it, your skill level, and your tooling.
I was using 2-1/2" coarse Kreg pocket hole screws. Kreg screws are supposed to be self-tapping, but the coarse-thread screws are intended to be self-tapping in softwood, and the fine-thread screws they intend for use in hardwoods aren't available in 2-1/2" lengths. I decided to drill pilot holes in the oak. Just to make sure, I did a test hole in the scrap piece I'd cut off.
