Continued work on the Main Spar Fitting.
More Work on Forward Spar Fitting
I’ve spent more time completing the Forward Spar Fitting and started work on the Main Spar Fitting SNX-T03-02
More Cutting And Filing Fittings
More cutting and filing away at the forward spar fitting.
Horizontal Stabilizer Fittings
I started working with the fittings made from angle. The first part I picked was the forward spar fitting. This is made from a piece of 2-1/2" x 2-1/2" x 3/16" angle that has to be cut down quite a bit. I started by cutting a length of angle down using my hacksaw. Next I marked up the first cuts and used my band saw. I need to get a proper blade as existing blade only has about 6 teeth per inch and wanders a fair bit. After cutting the angle I next used my files to clean up the cuts. Again, I discovered that I really need a vixen file.
Finished Forming The Last Of The Ribs
Today I finished forming the last of the ribs required for the elevator, ailerons, flaps and rudder. Here they are all layed out on the bench. The only thing remaining is the small joggle in the end ribs for the fiberglass tail tips.
Formed Long Bends On Flap And Aileron Ribs
The heading says it all. I will need to make up another short clamp bar for the bending brake to form the short flange on both ribs.
Deburring
I deburred all of the remaining ribs today. Now I just have to form them. I also ordered a set of offset seaming pliers to help form some of the sharp bends.
Layed Out And Cutout Remaining Ribs
Using the templates I made earlier in the week, I layed out the remaing aileron, flap and tail ribs and cut them out.
