Step 3: Mark and Drill Pilot Holes
Most lumber framing is done simply with hammer and nails, but screws with pre-drilled pi-
lot holes are used instead, the frame will fit tighter, last longer, warp less and will help pre-
vent the boards from splitting. Start by marking the width of your board on each end that is
to be drilled (
Figure 39
), so you can drill holes close to the center of the board. Use a drill
bit that is slightly narrower than the screws you plan to use. A 1/8th inch drill bit is recom-
mended for #10 screws in softwood.
