Step 3: Drill The Holes
Next you will want to drill the holes for the dowel rods.
1. Mark your arches with a pencil where you would like your rods. (Mine are 15" apart and 1/2 in from the edge.)
2. Drill with a 1/2 inch bit
3. Fill any chips or gaps in with wood filler.
4. Once filler is dried sand your edges smooth all around.
