Brief Description: Right Horizontal Stab Ribs and Skin
Assembled and final drilled ribs to front and rear spars on right half of horizontal stabilizer. Installed right HS skin onto skeleton. Straightened (fluted) and match drilled inboard ribs (HS-404R and 405R) ribs. Match/final drilled all rib and spar holes in right HS skin.
Upon disassembly I found an edge distance issue on both HS-404 inboard nose ribs. The bottom hole on both ribs was approximately 3/16" (1/16" too close) from the bottom edge of the rear flange on both ribs. The distance between the two hole in the flange was 7/8" on both ribs, so I added a third hole exactly halfway between the original two.
After dissassembly, I stripped the vinyl from the rivet hole lines on both HS skin and the VS skin. In preparation for assembly, I also stripped the vinyl completely from the interior of both HS skins.
I seem to have misplaced the speed handle I like to use on big deburring jobs, so I'm putting that off until I can get a replacement. I the meantime I will jump ahead a bit and start on drilling the vertical stabilizer.
