How do you elongate screw holes?
I'm looking for a quick, simple way to elongate screw holes when I attach a solidwood top to a piece of furniture.

Here's how we made 1⁄2 "-long slots to receive #8 screws for a recent project, Jon. With a 3⁄16 " twist bit mounted in the drill press and a fence in place to keep the holes aligned, we drilled three holes for each slot: one in the center and one at each end. Then, we chucked the same bit into a portable drill, placed the part on scrap, pulled the trigger, and rocked the bit against the remaining waste until we had a complete slot. Work carefully, and you'll get a clean, straight result.
Align each slot so that it runs perpendicular to the top's grain lines. All significant wood movement occurs across the grain.
