I'm really trying to wrap my head around how to use a pocket hole jig, and I have a few questions. Does the height setting matter when you're using it, or is it pretty much the same no matter what? For example, if I have a 2x4 that's 29 inches long, what size holes should I be drilling? I've decided to go with the Kreg Jig 320 after some research, but I'm unsure about the drill size I need to use. The video I watched listed screw sizes, which I've got down, but I'm still confused about what drill bit to use and how to set everything up. Most jigs look flat, yet the person in the video seems to be drilling vertical holes with a vertical jig, which is throwing me off. Any guidance would be awesome!

Kreg makes different drill bits depending on the screw sizes and material thickness. The height setting definitely matters, as it helps ensure the hole comes out in the center of the material. Also, consider the screw length based on the thickness of what you're joining. If drilling into hardwood, you might need a longer bit for the pilot hole. Just remember to make a test piece before diving into your project—it's easier to fix mistakes on a sample than on the actual pieces!
Regarding that 29-inch length, it won't affect your drilling process directly, but the thickness of the material dictates how you set your jig. Make sure your hole is drilled an appropriate distance from the edge so it'll fit nicely. If you’re going through thicker materials or hardwood, having a pilot hole could make life a lot easier. Don’t forget to set your drill bit’s collar to the right depth so it sinks just right!
The height setting on the jig is important—basically, you set it based on the thickness of the material you're working with. If it's 3/4 inch plywood, set it to that; for a 1.5-inch 2x4, set it to that thickness too. This influences the angle of the drill hole, ensuring that the screw goes into the right spot without sticking out. For screw length, you generally want it to be twice the thickness of the material. So for a 1.5-inch board, a 3-inch screw works well. The orientation of the jig doesn’t actually affect the results; just remember that if you're using a vertical jig, the side facing down is your connecting surface. It's all about getting those angled holes right!
Thanks for breaking that down—really helpful!
Good advice! Always better to test first.
