I first snapped a chalk line on the table. I then clamped the ribs and spar to the table making sure that the spar was perfectly straight with the chalk line. Next I laid the top skin over the skeleton and got the holes lined up. Using duct tape helped with this. Once everything was lined up I started drilling and clecoing as descirbed in the manual.
