How to Use Pocket Screws-Make Tight Joints
About This Project
Don’t be put off by projects that call for tight joints or simple cabinet building. The pocket screw system is so easy to use that even a novice woodworker can make strong, tight joints on the first try. It works like this: You clamp the pocket hole jig onto your workpiece and drill angled holes with the special stepped drill bit. Then you simply align the two pieces to be joined and drive a pocket screw at an angle into the pocket to connect your pieces. The result is a tight joint that’s as strong as a doweled or mortise-and-tenon joint but takes a fraction of the time to assemble.
In this article, we’ll show you how to set up the jig and assemble joints using pocket screws. We’ll show you techniques for assembling a face frame and a table leg and apron and for attaching shelf nosing. Refer to the instructions that came with your jig for ideas for other types of joints.
Less-expensive jigs that lack built-in clamps or alignment guides aren’t worth messing with. The Kreg Rocket jig is a great midpriced tool. The $60 kit includes everything you’ll need to get started: a pocket hole jig, a special stepped drill bit and stop collar, a 6-in. driver bit, a locking pliers–type clamp and a handful of pocket screws. Buy Kreg jigs at woodworking stores or on-line, or shop for a high-quality pocket hole jig with similar features (see the Buyer’s Guide).
Setup Is Straightforward
Pocket screw jigs are ready to go right from the package. All you have to do is slide the stop collar over the bit, adjust the bit depth and tighten the collar (Photo 1). The jig is initially set up for joining 3/4-in. material with 1-1/4 in. screws. Add the plastic spacer included with the Kreg Rocket and use 2-1/2 in. long pocket screws to join 1-1/2 in. thick material like 2x4s. To join 1/2-in. thick material, reverse the stop on the front of the jig (refer to the instructions included with the jig) and use 1-in. long screws.
The Stepped Bit Drills Two Holes at Once
Photo 3 shows how to mount the jig and drill holes. Put the bit in the guide before you start the drill. Let the bit come to full speed before you push it into the wood. Withdraw the bit once or twice to eject shavings. It keeps the bit cooler and makes hole drilling easier.
