File Joints for a Perfect Fit
Finesse parts after handplaning to create snug joinery.
Files are great for removing wood when a joint is almost together—but not quite. A file will delicately trim a joint until it slides home with hand pressure and closes without gaps. And because files remove wood slowly, you have control and won’t go overboard. Hand-tool expert Chris Gochnour explains how to choose the right file and use it to ensure gap-free dovetails and friction-fit tenons.
