03 JAN 09 - Is He Still Alive? - 2.0 Hours

Yes, I am! I would like to take this chance to thank the people (both of them!) that have continued to view the website despite my lack of progress (that means you, Dave).

Truth of the matter is, I have had a few life events that brought progress to a standstill on the airplane:

1.) Made it through my first year of an MBA.
2.) Had our first baby, a girl - followed shortly thereafter by -
3.) Deployed to Iraq

You might say that I burned the candle at both ends in 2008. (Are there candles with three ends?)

But, I am still here, alive and kicking, and looking forward to what the New Year has in store. I hope that you enjoy an excellent 2009 as well. As for the airplane progress, it will be slow for a while. But I am still fully committed to finishing it, even if the ETA must be pushed back.

Now, onto the good stuff:

The wing kit is here, has been for months, just begging to be worked on. But I've got to finish the pesky elevator trim tab first.

In looking at the
Van's Airforce forums, I have noticed that a number of builders complained about the folded edges of the elevator trim tab. So, I elected to cut them off! I have decided to use a couple of E-709 elevator end ribs as "riblets" in the trim tab. More to follow on that in a future update.

I drilled the trim tab horn to the trim tab skin, and then clamped and drilled the hinge to the skin and trim tab spar. Be careful here, as the spar has a tendancy to not line up with the skin when the bottom of the spar is clecoed to the skin. I ended up removing the clecoes on the bottom of the tab while I was drilling the hinge so everything would line up.  

Clamped Hinge to Tab
Clamping the hinge to the tab. I removed the clecoes on the bottom to make things line up propertly prior to drilling.

Drilled the Trim Tab Hinge
After the hinge was drilled, the instructions call for the top edge of the trim tab spar to be countersunk.

Countersinking the Trim Tab Spar
I used a piece of plywood as a countersink guide beneath the spar. I would recommend doing this any time you are countersinking .032" aluminum as the countersink will likely be deeper than the actual hole. If you don't have a guide beneath, the countersink bit will chatter and cause an uneven countersink.
