Rudder skins are dimpled

I dimpled rudder skins tonight. DRDT-2 works very well.
My mom dimpled a few holes too. This is getting to be a truly family airplane. 

1 hour 15 minutes today.

More rudder work today

Today I have made a lot of progress.
I have match drilled all holes in the rudder, but then I ran out of cleco's again. Page 7/6 calls for drilling and clecoing every hole both in spar and in the trailing edge. I started with spar (after I match drilled all stiffeners and ribs). By the end I had maybe 15 clecos left. So I decided to keep clecos in every other hole in the spar. That had freed up quite a few of them.
Then I drilled and clecoed every hole in the trailing edge.
After that I have disassembled the rudder and deburred holes and everything else that was not. There was quite a lot of deburring, but it is done.
I then proceeded to dimple ribs and stiffeners.
Interesting, plans call for dimpling of bottom rib (R-1004A/B) and spar (R-1002). I used my pneumatic squeezer to dimple stiffeners with #40 (3/32) dies. Dimples look very nice. However, when I dimpled bottom rib, dimples did not look very pronounced. A rivet does not set flush in there. I decided to ask Vans - should the bottom rib and spar flanges be countersunk instead of dimpled? Let's see what they say.
Aside from skins and spar everything is now dimpled.
Not much to show, but here is the rudder after match drilling during disassembly.

Hours today 7:45.
Total hours on rudder 12:45
Total hours on build 82:45.

Vertical stabilizer is completed

It is really done. Everything is now riveted.
Dasha said: "Какая классная штука" (What an awesome thing!)

My wife has helped to buck these rivets. What would I do without you?


Now, let's help dad with the next phase of the airplane.
Total hours on vertical stabilizer - 70
Total house on build - 70
This number of hours is approximate. Since my initial log was hacked and lost, I can only guess. I know it was slow, so let me make it 70 hours.

Vertical stabilizer is almost finished

Today Galina and I have almost completed vertical stabilizer.
Honestly, I was extremely anxious about riveting the VS. After all, it took me almost one and a half years to overcome initial failure to set good rivets.
So today, sometime in the afternoon, Galina and I have bucked rivets on the middle nose rib! It certainly makes a whole lot of difference when two people work on the plane. Then we kept riveting and by evening our VS is almost done.
I just need to rivet bottom middle rib and then skin to the spar.

Rudder is assembled, well, almost.

Run out of clecoes!
Today I made a good progress on the rudder. I spent evening putting together all parts of the skeleton. Deburred everything I needed and could - stiffeners, skins. Then put everything together.
Interesting note - I did not pay attention to where bend is displayed in the drawings. There are two sets of parts - shear clips and stiffeners which are bend, but, of course, they are drawn flat. So when I marked and cut stiffeners, I marked "L" on my my left and "R" on my right.
When I was putting skeleton together, "L" should went on top of "R", but not in my case. I have the opposite - "R" goes on top of "L". This is not a big deal because parts are the same and I still did what the plans call for - the part on the left goes on top of the part on the right. Still, need to pay close attention to where the bend is. I'm suspect there are a few places in the build where this is very important.
Finally, I've run out of clecoes and had to stop. The rest of the clecoes are on the vertical stabilizer which I hope to start riveting skin on tomorrow.

Rudder build continues

In the past couple of days I spent a few minutes here and there preparing and cutting stiffeners. 
Today I have deburred stiffeners, prepared bottom rip, rudder horn, match drilled and assembled what is seen in the picture.
Maybe spent an hour and a half.
Barney and Eva are visible through the lightening holes. :-)

Rudder begins

Tonight I started cutting first rudder parts.
I have separated and deburred top rib, bottom rib, and shear clips.
This is easy part when one remembers how tools work.

Vertical stabilizer is ready for riveting

This evening my wife and I have done WORK on VS!
My last note in the plans was made at this point of build on June 25, 2013, so it is a big deal that the work has been restarted.
We have riveted middle front rib to the inspar. I used 3 AN470D5-5 (5/32) rivets to fix by hack job when I drilled out damaged middle front rid.
Then we put skin on the frame and clecoed it.

The revival

After almost two years I've picked up my tools and tried to do something about the airplane.
I final drilled new VS-1013, deburred it and shaped so that it will fit the VS. I almost went to rivet the whole thing, but realized that when I drilled out old one, I've made holes in inspar too large for designed rivets. 

I will wait for Vans answer about what size to drill and which rivets to use. Maybe I can drill two new holes of correct size, but that may lower the stength of the whole part... Better wait for Vans.

While waiting for answer I primed it too!

Vans said it was acceptable to use 5/32 rivets and drill #21.
