Step 37: Attach center backrest slat

Picture of Attach center backrest slat
Find and mark the center of the top and bottom back rail.

Drill and countersink a hole on the bottom of the slat, then attach to the bottom back rail.  Line up the top slat/rail, drill, countersink, and attach.

I would not use glue on the backslats-- you may want to move/adjust them later.
