Section 8 - Horizontal Stabilizer (countersinking/dimpling; substructure)

Lots of progress the last couple of days - these myriad parts are starting to look like a horizontal stabilizer ... well, the skeleton anyway.  Much of the work has been deburring edges and holes ... a thankless but necessary task that took a half dozen hours.  Not shown, dimpling the ribs and skins, a task I very much enjoy (using the DRDT-2 is therapeutic). Below are a few pics from this midpoint stage in assembling the H.S.

Countersinking a couple hundred holes on each side of the front and rear spars, and stringers (rear spare shown here). Aluminum shavings/filings everywhere!

Stringer assembly clecoed to front spar:

clecoing and riveting stringer assembly and inspar ribs to front spar (love that pneumatic squeezer, especially now that I figured out how to use it):

Ready to slap this puppy into the skins (my helper in the distance is working on his own project this evening):

It doesn't look that big in the picture, but the horizontal stabilizer skeleton is approximately 9.5 feet long:
