Started Spar Assembly - Section 13






Started the assembly process today. Twenty attach angles were constructed by cutting them from the 4 pieces of supplied angle. Two attach angles were constructed by cutting them from the 1 piece of supplied angle. Cut/separated with the bandsaw. Excess material removed with the disc sander. All edges polished with a file, sandpaper and with the small scrotchbrite wheel in an air die grinder. The small Scothbrite wheel made short work of rounding all of the corners and polishing the pieces. There is a small hump every 2.75 inches on the edge of the angles that should be removed. Most probably resulted during the machining process at Van's. Match drilled the rib doubler to the spar. Then, tapped the AEX wing tie downs in the spars after drilling to the correct size. Before starting, decided to make a small wooden jig to hold the spar in the vertical position. See the pictures.

Time - 4 hours
