Began TricycleLanding Gear & Engine Mount (Section 40A)

Screen Shot 2020-04-25 at 8.11.49 PM

 

Separated the gear attachment angles on the band saw. This is a hefty chunk of aluminum angle. It took a good 15 minutes to get through it on my puny band saw.

I decided that a new tool was in order to make the diagonal cuts. So I picked up a DeWalt Angle grinder and some cutoff wheels. It cut like butter. It took all of five minutes to get both angles cut.

 

Scuffed the angles as well as the other parts. Ready for priming tomorrow.

Countersunk the canopy

Broke the top edges of the side skins with the edge roller. Sawed a kerf into a small wood block on the band saw and used it to tweak the edge of the top skin under the slot and aft. Dimpled the canopy attach holes in the side skins.

 

Countersunk all of the holes in the canopy with a zero flute countersink.

 

Fabricated that aft canopy seal with a hole punch and a razor knife.

Finished rear window and started on Canopy Latch

I used the edge roller to break the edge of the top and side skins where they meet the rear window. I final drilled the skins #27 and dimpled the holes for #6 screws. The squeezer wouldn’t fit into the space between the top skin and the roll bar brace. After a fair amount of ass-scratching I tried using a #6 screw and a K1000-06 nut plate to press the dimple into the center hole. It worked well.

I decided to wait until later to actually install the window. This will enable better access to the fuselage and keep me from beating up the window while I’m working on the rest of the stuff. But everything’s done and all I have to do is add some sealant and screw it in. For sealant I’ve decided to try Lexel. It’s a clear solvent based sealant that is safe for acrylic. Other builders have reported good success with it.

 

I separated, deburred, and painted the stiffener angles. I’ll rivet these in place as soon as the paint dries.

 

I picked and inspected all of the parts for the rest of the canopy.

I peeled all of the parts for the canopy latch mechanism. I separated the peices that needed parting. I deburred and scuffer all the parts. Then painted everything to match the interior.

 

I test fit the canopy latch pins in the bushings that I installed in the roll bar. I realized that I neglected to mask of the bushings when I painted the roll bar and got some paint in there. I wrapped some sand paper around a brass drift and used it to clear the paint. Everything fits fine now.

Began Work on Upper Forward Fuselage (Section 35)

Screen Shot 2019-12-07 at 11.38.33 PM

 

Picked, inspected, and peeled all the parts.

 

I separated all the parts that required parting and began fabrication. I made the canopy release pins by shortening and chamfering the ends of a couple of eye bolts. I made the canopy release push tubes from some aluminum tubing.

Began work on rudder and brake systems (Section 33)

Screen Shot 2019-11-26 at 8.44.59 PM

 

My sister and brother-in-law were in town for some turkey. So I enlisted John to help with prepping and painting all the rudder pedal parts. I decided to flat black everything. I’m going to go with some grip tape on the face of the brake pedals. We got all the parts cut, deburred and scuffed. Then painted with Rustoleum Painter’s Touch rattle-can.

 

We’ll let the paint cure tonight. Then we can assemble tomorrow and shoot another coat to cover the rivets.
