Aileron Nose Ribs
Started: October 12, 2003
The Aileron Nose Ribs are the first ribs so far that do not utilize the Master Formblock. A new template was made from MDF using the full size drawing in the plans.
Two Jig Holes were made as well as relief holes for each of the tabs that will be bent to 90 degrees. These were all 1/4" holes.
The formblock was cut to shape to allow bending of the tabs over. Again a 1/8" radius was filed into the edges.
And here is one of the ribs after forming:
A Unibit was used in the drill press to cut the 3/4" hole in the forward corner of each rib. This hole will be used for the lead filled tube to create a counter-weight balance. A simple jig, made from some scrap wood, was used to accurately locate the hole in each rib as shown:
And here is the finished Aileron Nose rib:
