The hot wire process is one of the most amazing steps, taking a one dimensional template and creating a three dimensional wing part in just a few minutes. WOW... cool stuff.
Torque tube hinge inserts are riveted in and the tubes are lightly sanded.
Sand the torque tube channel, I used rolled up sand paper glued to a stick. Sand the channel large enough so the tube fits without cracking the foam, the bottom is very thin. Next macro the tube and the channel line up the hinge using the hinge jig plates and the hinge rods, weight down on your flat table for cure.
Sand the elevators to fit the gauge templates, making sure that you leave room for the glass. The gauge templates leading and trailing edge must touch. The hinge point have been filled with silicone to keep the epoxy out.
Glassing the bottom you should make sure that you make it as dry as possible, this helps with weight and balance and fit to the canard.
End glassed with flox corners and the end tube plug riveted in using the hinge rod to set location.
Bell crank riveted in place.
In this picture you can see the lead weight used to keep the elevator in a nose down position.
Here is the hinge jig and the nut pocket used to bolt the torque tubes together.
Weighting down the entire elevator component is very important for good operation and fit once mounted on the canard.
Setting the hinge frames into the canard at the correct angle for the elevator travel in relationship to the canard. Set here until flox cured.
The jig holds the lead weight at the correct angle until the 5 minutes epoxy cures.
Sand and prep for glass
Glassed, peel & ply, after cure sand elevator smooth at elevator weight is attachment point.
Create pockets in the canard to except the elevator lead weights, making sure to have enough travel, glass pocket with 2 layers of bid.
