Chapter 19 - Wings - Part 2

Last Friday my brother came down from Seattle and helped me cut the first of the three wing sections. I really messed up when ordering the foam and so I only had enough to cut the outboard section.

After cutting the core, we cut the wiring conduit and split the cores allong the shear web. Next I bonded the blocks togather with micro to complete the two individual foam coars. These will be bonded back together after the shear web is layed up.

Well, as the plans say, "this is the big one", the wings.

First step was cutting out and assembling the wing jigs. These are used to allign the wing foam cores while they are bonded togather and while the shear web is layed up.

Each jig is split into 4 peices and bolted togather so that they can be separated for different layups.

When I constructed the canard, I purchased preformed foam cores. However after assisting Steve Parkins cut one of his Cozy MKIV wing cores, I reallized how easy it was and decided to cut my own wing cores.

After I completed the wing jigs I bonded the wing templates from the A drawings onto formica laminate and cut them out. These templates guide the hot wire cutting tool to form the airfoil. Also included are templates for cutting torque tube access, aileron cutouts and wiring conduit and winglet.


Here is a photo of the hotwire cutting tool I constructed. An assistant will be required to weild this while cutting the foam cores.


The foam blocks are enroute. In the meantime I will be transfering the "talking numbers" and other information to the back side of each template. Sometimes a reverse template is required depending on weather or not the template is used inboard or outboard of a block, and of course when the other wing is constructed as well.
