This is going to sound like a noob question, but I am a total noob. I am building a cabinet of drawers, 17 drawers to be exact. My carcass is built, and now I need to start the drawers. I really want to use a drawer lock joint, but I was told by a guy at Woodcraft that I would need to clamp the drawers or they would rack. He suggested pocket holes. I have the Kreg pocket hole system, but I have a Kreg router table, too. I have built an entire workbench and hutch using the pocket hole jig, and while it has its place, I'm not crazy about it. My question is this: If I use the drawer lock joint, do I need to clamp the drawers? I was just going to glue and pin nail. I don't have but a few clamps and not real interested in buying a bunch of clamps just for this project. Thanks in advance.
