February 24, 2005 - Right Flap

I can't put it off any longer; it's time to tap the tie-down brackets.  My father-in-law lent me the tapping tool.  It worked great.
The tie-down loop screwed right in, no problem. 
Next, I had to drill a hole in the leading edge skin where the tiedown loop goes through.  On the left wing, I mistakenly made the hole bigger than it needed to be.  The instructions said to draw lines so you know where the center of the hole should be.  I did that on the left wing with poor results. 
 
This time, I noticed the leading edge skin had a predrilled hole which looked to be directly centered over the tiedown bracket hole.  I figured it is probably accurate since every other hole in this RV-7 kit is absolutely perfect.  So I just drilled the starter hole out to 1/8, then used the Unibit to enlarge the hole to about 3/16.  It came out perfectly. 
 
I heard somewhere recently that people learn mostly through their mistakes.  That is so true.  At least in my case it is.
Now it's time to deburr and dimple and leading edge skins and ribs.  Here I am dimpling ribs.
Dimpling the skin.  Later on, Lynnette and I used the C-Frame to dimple the inner holes.
