And the start of clipping off the ailerons.
There are several good ways to do this job. This way is nice because the blade cuts a perfect 3mm slice. It also leaves the faces perpendicular to the wing surface.
The 3mm slice is great because it will alow capping the aileron and the wing cut with 1mm balsa and leave 1mm clearence, which after covering will be about a .5mm gap, perfect for smooth airflow with neutral aileron and beautiful to look at.
This table saw has all of the stops and squaring devices to set-up and run a series of wings through rather quickly. PLEASE, if you ever try this method, BE CAREFUL. Table saws are one of the woodworking industry's number one finger takers. Always be mindful of the blade. In this operation the blade is set at maximum height and angled to cut the proper angle.
Here it is ready to be turned on and make the cut.
