Primed everything and Riveted left top skins

Scuffed the top skins, wing walk doublers, and stiffeners and wiped everything down with acetone.

Mixed up a batch of P60G2 and shot everything with primer.

Clecoed the left skins and doublers to the left wing substructure.

Remy helped my rivet the skins to the ribs and spars. Prefers bucking and I prefer shooting so it all works out.

Finished riveting the spars and ribs and clecoed the J stiffeners in place. I’m really pleased with the result so far. The riveting went really smoothly. No dents!

Primed and started riveting the rear spar and Ordered Engine and Prop

Had an awesome time at Sun N Fun with Jared, Wes, and the Family. That’s me ordering an engine and prop in Van’s tent! And that’s me and Remy sitting in the RV14 at Van’s booth. Suddenly this is getting more real.

 

We got back from Lakeland this morning and I got right back to work. No rest for the wicked! Primed the rear spars and all of their associated parts.

Clecoed the aileron hinges together.

…and riveted them.

Primed everything and started assembly

 

Wiped everything down with acetone and then shot primer. I did the spars first, then the ribs in two batches, and finally all the other small parts.

 

 

Riveted the flap hinges and hinge ribs to the ribs. I started using the squeezer but it couldn’t reach most of the rivets so just switched to the gun and shot the rest of them.

 

 

Assembled and riveted the the torque tube brackets and riveted them to the inboard ribs.

 

 

Clecoed the ribs to the spars and reinstalled the AN3 hardware and torqued everything down. I also installed the snap bushing in the systems holes in all the ribs. Many of them were a bit loose. I’ll have to give some thought on how I want to resolve this.

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.

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?
