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.

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.

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.

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?

Riveted together the inboard ribs, web, and stringers.

IMG_1732

Clecoed and riveted the ribs to the front spar

IMG_1735

Clecoed and riveted four nose ribs to the skins. Special thanks to Jared Solomon for lending me his HS cradles. Also for the awesome flight flight yesterday in his RV-14. Makes me want to build faster.

IMG_1736

IMG_1737

Clecoed the forward spar and associated substructure to the skins. Ready for final riveting. Should have the HS buttoned up tomorrow!

A very satisfying day of progress!

Vertical Stabilizer Complete!

Scuffed and prepped the new parts. Then sprayed them with primer.

Clecoed the skin to the forward spar and ribs and started riveting.

IMG_1679

Finished riveting the skin to the forward spar and ribs.

IMG_1681

Clecoed and riveted the rear spar to the skin and ribs.

IMG_1682

VS Complete! Very pleased with how well it turned out. Once I replaced the parts I messed up, everything went smoothly. I’m much happier with my workmanship than the first attempt. A little experience makes a world of difference.

IMG_1684

Rearranged the work benches and started picking parts for the horizontal stabilizer.

Primed rudder parts, assembled spar, drilled trailing edge

I primed all the rudder parts and skins today. I picked up a roll of hardware mesh at Home Depot and put it up on some blocks over my paint table. I did this to keep all the small pieces from being blown around by the spray gun. It worked really well.

img_1562
All dressed up and no place to go!

 

img_1560

I got the shipment of VS replacement parts from Van’s today. Unfortunately only four of the five parts I ordered arrived. They shipped the wrong part for the fifth on. I ordered a VS-705 they shipped an E-705. I called and they’re shipping the correct one. Oh well. I’ll just continue on with the rudder until it arrives.

img_1563

I riveted together the spar, reinforcement plates, counterweight rib, bottom rib, rudder horn and shim. The I screwed up and riveted the rudder attach nut plates to the wrong side of the spar. Drilled them out and re-riveted correctly. Cost me six rivets and an extra thirty minutes. No harm no foul.

I’m still struggling with my riveting technique with the gun. There was one rivet on the rudder horn that couldn’t be reached with the squeezer. I managed to put a big smile into the rudder horn. I think it will be okay.

img_1565

I made a drill guide from a paint stirrer so that I could more accurately drill perpendicular to the chord of the rudder. I cut a 6 degree angle on the end and held it flush to the rudder and aligned the drill to the edge of the stick.

Off to Vegas tomorrow for a conference. won’t be making ay progress until next weekend.
