Now on to something more fun. Skin.

Rudder Skins Test Fit

Test fitting the rudder skins today. Really all components are complete and are clecoed together. Now to disassemble, deburr, dimple prime and then rivet together.

Rudder Frame

OK all, now that I have rudder skins all ready to go, I need a rudder frame to put them on. So that is my task for tonight.

Shape the control horns 

Assemble the Frame

Test fit the Skins

Make the Horn Brace Box

Rudder Skins

Today I am working on the Rudder Skins. The Skins will use Stiffeners to allow them to keep their shape when being forced into the wind. The Stiffeners must be cut out from angle aluminium and formed to the correct shape. Used Metal Shears to cut out the rough shape and finished up on the Scotch Brite wheel.

Next Dimple the Stiffener and Skins

Then Prime and Back Rivet. To get the height correct I used a piece of card board around the Back Rivet plate.

Then use Scotch Tape to keep the rivets in place
