Primed everything and started assembly

Primed all the aileron parts.

 

Riveted the various hinges and doublers to the various ribs.

Clecoed the nose ribs to the spars and set in the skins with the stainless counterbalance tubes. Match drilled the inboard and outboard holes from the leading edge of the skins to the counterbalance.

Primed all the tank parts.

When I bought my tools I bought my tools for this project, I decided to buy a DRDT-2 dimpler. I decided not to bother with a c-frame. Until this point I have not found anything that I couldn’t do without a c-frame. Today I needed to fill the locating holes in the inboard and outboard ribs with AN470AD6-5 rivets. I don’t own any tool capable of setting those big rivets reliably. Fortunately Jared offered up his c-frame and I went to his house and got these rivets set. Thanks, man! Ended up cutting the rivets down to like a 6-3. They are not structural and they were way to long.  They just plug up the machining holes in the external fuel tank ribs. The shorter rivets set perfectly with the c-frame and a heavy hammer.

I primed the exterior side of all the fuel tank parts.

I riveted the bearings for the aileron controls to the tank attach bracket.

I riveted the shims and nutplates to the tank attach brackets.

I riveted the nutplates to the aft inboard ribs. I couldn’t get a mushroom set in between the clecos to rivet these. So I used a back rivet set on the tail and a bucking bar on the factory head.

I’ve completed everything I can on the Tanks until I get the J-Channel I ordered from Van’s. On the bright side… I received the tools I need to install the landing light lenses so that will be tomorrow’s project.

Prime time

I deburred, scuffed and primed all of the remaining empennage parts including the top skin and the upper side skins. I’ve just about run out of parts. Once I get my static line and nut plates from Van’s, I’ll be able to finish riveting everything.

Hey–this thing’s starting to look like an airplane.

Scuffed and primed the side skins.

Machine countersunk all the holes in the longerons.

Dimpled the remaining stiffeners.

Dimpled the skins.

Clecoed everything together.

In my excitement over putting all this together I neglected to peel the the blur vinyl from the rivet lines. I’ll have to remove some clecos and do that before I rivet.

I also riveted the aft bulkhead to the aft bottom skin.

Primed Tail Cone Parts

I peeled the blue vinyl from the j channel that’s formed into the edges of the bottom skin so that I could scuff and prime those along with the inside of the skin.

IMG_1923

First batch of four ready to shoot.

IMG_1924

Second batch was the rest of the bulkheads and bell crank ribs (not pictured) and the third batch included the longerons and stiffeners. The last batch was the bottom skin.

IMG_1925

Et viola!

IMG_1926

Tomorrow I’ll begin assembling the tail cone. Once I get the substructure assembled and riveted to the bottom skin, I’ll have one more big scuff and prime session for the skins and the few remaining substructure components.

Primed, Dimpled, and Started Assembly

Busy day of building today! Started off with a Home Depot run to pick up some paint pots and gloves. Then I got set up and shot all of the elevator part and skins with primer.

IMG_1777

That was a lot of stuff to prime. Didn’t mix enough and had to make a second batch to finish the skins.

IMG_1778

Once the primer was dry, I brought everything in the house and dimpled the skins and all the ribs, spars, and other miscellaneous parts. Clecoed the forward half of the trim tab hinge to the aft spar and  machine countersunk the portion of the aft spar that attaches to the hinge. Did a similar job on the trim tab spar later.

IMG_1780

Modified my female #40 dimple die to enable dimpling of the nut plates needed for the trim tab servo doubler. I just ground off a bit of the edge on the bench grinder.

IMG_1781

Here’s the modified die in action squeezing a dimple into a nut plate.

IMG_1784

And here are the nut plates installed in the doubler.

IMG_1785

I machine countersunk the parts of the trim tab pushrod and double flush riveted it together. The plans called out AN426-3-3.5 rivets but those were too short. I used -4.5’s and they came out perfect.

IMG_1787

Clecoed together the trim tab with the spar and trailing rdge and final drilled the holes in the closeout tabs.

IMG_1788

I machine countersunk the the trailing edges for the trim tab and left elevator using the tapered-pilot countersink cutter. I’m still waiting for the right trailing edge from Van’s to replace the one a screwed up.

IMG_1790

I riveted the trim tab horns and spar to the bottom trim tab skin.

IMG_1791

Taped off the places on the skins and spar where I’ll bond the ribs and trailing edge in order to prep for the ProSeal and trailing edge tape. I removed the primer with isopropyl. I scuffed with 150 grit sandpaper. Then cleaned the scuffed areas with acetone. Then I removed the tape.

IMG_1792

Tomorrow will be my first experience with ProSeal. I’ll be using it to glue the trim tab ribs in place. Plans call for a “well and truly flat” work surface on which to weight down the trim tab while the ProSeal sets up. I don’t consider my workbenches to be “well and truly flat.” So I’ll be off to Home Depot again tomorrow to come up with something. Maybe a steel plate or a 3/4″ MDF panel?
