Rose Arbor - Step 4
Fit the arch mullions: Mark a line 4 inches above and parallel to the bottom of the back of each arch. Align the bottom of the crossbar to the line, glue and nail. Mark the crossbar’s center point and measure left and right 4½ inches, marking the two points. Mark the center point of the arch top and points measuring 9½ inches to each side on the curve. Extend lines through the marks. Center a mullion on each line, flush to the arch top. Mark the short mullions’ bases and cut bevels. Glue and side-nail mullions to the arch; only glue it to the crossbar. Reinforce bottom mullion glue joints by drilling 1⁄32-inch nail holes through the crossbar underside into each mullion, fastening each with an 8d finish nail.
