    Horizonal Tail Complete

    Went to work and finished up the horizontal tail this past week, was pretty busy with work, did this in 30 minute blocks. Hydraulic squeezer does a great job. Yeah, first complete part. On to the Vertical fin.

    Rivet Left HT Fwd Spar and Ribs

    Work off an on this week and put in 6 hours on the left horizontal spar riveting. Here’s the top side, left side, done for now. Overall happy with the way the rivets turned out, needed to drill out around a half dozen that weren’t quite right.  Here’s the left bottom nearly complete. \ Hope […]

  • Rivet HS404/405 to Front Spar

    Rivet HS404/405 to Front Spar

    First time bucking rivets… practiced a couple times, then asked father-in-law Jim Paschall to help out with the bucking bar.  Took the advice I’d read about clamping the spar to the table first and it went well. Clecoed together: Done, roughed, reprimed small scratches.  Forward side of front spar. Aft Right of Forward Spar. Aft […]

  • HT Spar Rivet Bearings

    HT Spar Rivet Bearings

    Riveted hinge brackets to the HT Rear Spar.  Bought a faulty torque wrench, new micro-torque wrench ordered, snapped off an A3-5 bolt, new ones in the mail. Previously oversized three holes when drilling out less-than-perfect rivets.  Read a number of blogs that suggested several fixes, and I tried those, but not happy with the results.  So, […]

  • Horizontal Tail Skins Buff, Clean and Prime

    Horizontal Tail Skins Buff, Clean and Prime

    Was hoping the zinc chromate would make it to the last forward spar but it didn’t.  Ordered a couple more cans which should be here tomorrow. In the interim, i was able to buff, clean and prime the outside of the tail skins with the NAPA 7220 so many have recommended.  Not so hazardous to […]

    Debur, dimple, buff and prime the front right horizontal tail spar.  Will attempt to get to the front left this evening. Also, cleco’d the left skin on some structure to “get a feel.”  Looking good.

  • Horizontal Tail Rear Spar Rivet

    Horizontal Tail Rear Spar Rivet

    Needed a break from the buffing and priming so moved ahead to some riveting.  Been very anxious about this since it has been about 15 years since I’ve done this! Directions suggested putting tape over the holes for hinges/etc. so as not to accidently rivet them shut prematurely. I pulled out the hydraulic rivet squeezer, […]

  • Debur, Dimple, Buff and Prime RR Spar

    Debur, Dimple, Buff and Prime RR Spar

    Three hours to finish up the right rear spar, now drying.  With the new Scotchbrite wheels life is much easier.  Sticking with the old standard green zinc chromate primer since I started with it for the internal structure of the horizontal tail.  Don’t want to take any chance of disimilar chemical corrosion.  Mini-spray booth is […]
