Wings have arrived!

So the wings finally arrived.  Vans missed their lead time and projection a little bit and it took a few extra days for ABF to decide to deliver my kit so this added up to about 3 extra weeks I was not expecting for lead time.

ABF canceled delivery three days in a row and ended up delivering my kit at about 7PM on a day where they claimed the delivery would take place between 9-5. 

When the truck finally arrived, I found that the spar box was in great shape but the other crate was busted open, missing part of the lid, bottom panel pulled loose, two metal bands missing, and the skids on the bottom broken off.

Thanks ABF!  You are now officially 0 for 3 kits (RV7 kits included) that you managed to deliver to be without severely damaging the crate!

 At first I figured there was no way that the contents would be intact and or not damaged.  Much to my surprise it appears that everything is still in there!  I have to do a complete inventory to be sure but it is looking good so far.

 Those beautiful spars are like airplane porn!

After pulling everything out and getting a look at it, all the parts seem to be undamaged.  The skins are OK  and while I still need to do a complete inventory to make sure nothing fell out, it looks like I got lucky!

Still waiting on wings!

So I really got behind the kit lead time curve on this one....

Van's lead times seem to be higher than what I am used to and they missed their estimate a bit.  Also the freight company is taking their sweet time getting the kit to me.

Hopefully I will get my wing kit tomorrow.

Still awaiting wings.....

Wing kit was suppose to be crated last week and I had hoped to be shipped by week end.  Still has not shipped as of today.  Best advice is order early as you can.  The lead times seem to be long right now!

Waiting on wings

I did not die.....

Just waiting on the wing kit to arrive.

I made the final payment today and crating is scheduled for the 6/17/19.

I have a couple more things I can do to the tail kit but I am dragging my feet.  Vacation next week so no progress will happen till after.

Later gator!


I did forget to post these pics of me drilling the elevator horns:

 Temp installed the left elevator.  Sanded down the drill bushing and put it in the center bearing.

 Used it to drill the left elevator horn.

 Switched sides and drilled the right elevator horn.

 Then I upsized the hole to almost 1/4" and then final reamed the hole to exactly 1/4" on both sides.

 Deburred the holes.

Deburred the other side.

Mounting the empennage to the tail cone #3

I did not follow the directions and mount the elevators to the HS on the bench like they tell you to.  The only reason I can see they have you do that is to help stabilize the whole mess.  My HS is already mounted to the tailcone and I used straps to help keep it stable.  So now I am going to mount the elevators.

First I need to install the rod end bearings into the elevator spars. 

 I made this tool back when I built the RV-7.  It works like a dream at installing rod end bearings into nutplates.

 Detail of how it is made on the business end.

 The bearing goes in like this.  The way it is made, it puts the pressure on the outside of the bearing and not the ball which can damage these things.

 Get the bearing started in the hole and twist to the desired depth.  Easy peasy!

I installed these exactly per the plans which is 7/8" from the center of the ball hole to the face of the elevator front spar.  To make it easier, add 3/8" to that dimension and measure 1-1/4" from the top of the outside edge of the bearing assembly to the front spar face.  I used the depth gauge feature of my digital calipers to do this. 

Amazingly this worked like a treat!   The elevator counterweight ended up perfectly aligned with the HS!  No goofing around with the bearings required!

Mounting the empennage to the tail cone #2

Got started tonight by drilling the rear HS spar to the vertical spar mounting brackets.  Starting with #30 drill to get a pilot hole.

Then moving up to a long #12 drill for final hole size.

Then I deburred the holes.

And installed the hardware called out in the plans.

Then per the plans I made this wood block to go between the front spar mounting tabs.  I then clamped it to the aft deck per the plans.

Checked about a dozen times for square.  It was really close out of the box.  I only had to move it 1/32 of an inch.

Once happy I used the front spar mounting tabs to drill the aft deck and the doubler underneath it.

Then I installed the hardware called out in the plans.  No problem with edge distance here!

Other edge distance issues here either.

Then I bolted on the VS front spar mounting plate.  Amazing that this is all there is holding the VS front spar on the plane.

I then match reamed the top rear spar holes to the tailcone and installed the called out hardware.

Next I match reamed the lower holes and installed the called out hardware in the upper two.

Next I had to machine countersink the bottom holes to receive a flush head structural screw.

Here are the lower hardware in place.

Next I used the rudder hinge bracket as a guide to drill a #30 pilot hole in the whole assembly.

Then I punched it up to #12 for the hardware.

Deburred both sides of the hole.  And installed the called out hardware.

Next I installed the VS front spar bolt.  It is subject to rotation so they have you use a castle nut and a bolt with a cotter pin hole.  I won't do that now since it all has to come apart anyway.

Inside shot of the rudder stop/hinge bracket hardware.  Not enough threads for me showing so I will either go with a thin washer or a longer bolt at final assembly.

A ton of work in this pic!

Mounting the empennage to the tail cone #1

 Got started today with deburring the VS to HS front spar mount.  I still can't believe that this is all there is that holds the VS's front spar to the plane.....  I also fabricated the HS stab front spar mount spacers per the plans.  I used the band saw to cut em out.

 Next I match reamed the VS front spar mount plate to the HS front spar with a #12 reamer.

Next I reamed the top bolt hole to 1/4" full size.

 Then I deburred all the holes.

 HS front spar hole deburring.

 The back side...

 Then I went ahead and started prepping for drilling the HS mount holes onto the tailcone.  I placed the HS on the tailcone with the spacers I fabricated.  I used some straps to ensure the whole thing remains level and can't fall over.
