Wings - 10

09/29/2013 8.0 hours, 217 hours total. Had a productive day. I was able to finish the left wing and start on the right wing. Once again, I had help from Dane. Dane attached the tailing edge spar and then help set-up the build configuration for the right wing. 2.5 hours

Left wing forward stub spar attached.


Snap in grommets installed in each nose rib. This will support wiring to position lights on outboard wing. And the color of the position light on the left wing is....? All leftee's are red.
 Tailing edge, rear spar left wing is attached
 Now I thought this was pretty clever. I'm running out of horizontal space, so I'm using vertical space. I'll build the right wing over the top of the left. It helps to be tall. The elevated platform is made of bricks and wooden shelves. Plenty of clearance and a stable platform.
 Here's another view....
 Right wing, main ribs are riveted in place. LP 4-3 and 4 - 4 rivets.
 Tipped on it's side ready for attachment of the rear trailing edge spar.
 Nose rib attachment to follow.

Wings - 9

9/22/2013 11 hours, 209 hours total. It has been awhile since I've posted an update to this blog. September has been a busy month and build time has been limited. I was in Reno last weekend for the air races. Had a great time with a couple of old college buddies. Great time!!

I have been making progress and even had some help from a friend of mine, Dane. This work centered around prepping the main and nose ribs. Important and time consuming work. I finished priming the ribs yesterday and started assembling the left wing today.

Okay, all ribs ready for priming. Deburring, sanding and smoothing and cleaning complete. Ribs are tagged so I remember which ones are left and which ones are right.

This is the set-up I used to paint the ribs. I wanted to paint outside, but it is too windy and too warm. So I settled in the garage and I used spray cans for the primer. This is an expensive way to go, but I was anxious to make some progress. This is a before shot!
 After shot!
 Left wing main rib assembly. You're looking at the bottom aft main ribs in this picture. Pretty easy assembly. Six rivets, LP 4-3, to the attach flanges per rib.
 Aft main rib attachment complete!
 Nose ribs are cleco'd on. You really need to follow directions with the rib attachment. Some are different- flanges trimmed; some untrimmed; some both forward and aft trimmed; some with nutplates. The instructions indicate that the final inboard nose rib should be the one with three nutplates. I've reviewed the instructions- don't see any instructions to attach three nutplates on a single rib!! I'm investigating before riveting! This is an outboard view.
 Another outboard review
 Outboard view with aft spar cleco'd to the main spars. Garage is getting crowded with just this one wing. Need to figure out what I'm going to do!
