Wings 7 (2.0 hrs)

I finished one of the two tie down brackets tonight. The picture below shows the completed tie down bracket after I installed and torqued the bolts. Unfortunately I could not finish the other tie down bracket because I’m out of AN426 3-7 rivets. I will have to steal some from another builder or have some sent in my next batch of items from Van’s. It will be awhile before I’m not able to access that part of the plane so I’ve got time.

Here is the other bracket waiting for rivets…

After the brackets were complete, I set about measuring and cutting the wing walk doublers. I used a set of tin snips my buddy Denny got for me and then a file to make the dimensions as close to perfect as possible. I’m a visual person and I had a pretty good idea how the doublers were installed, but since the skins are next, I started hanging the top skins to check the doubler and gain an understanding of how everything is fitting together.

Here is one of the two wing walk doublers I made tonight. All in all a good night in the shop. On a side note, my wife Maria got her US citizenship today!!!

Wings 6 (12.0 hrs)

Not a lot of pictures or proper updating for the blog this weekend. I’ve combined two sessions into one post.

On Saturday, Jack Savage agreed to help me rivet the spars and ribs together. One person can do it, but it is much quicker and easier to do it with two people. One person is fairly likely to make a mistake too.

On Sunday, I made sure the wings were perfectly true using the digital level and some plumb bobs. This required the installation of the bottom brackets to hold the wing in proper position. I will probably check everything again before drilling and riveting skins. I figure the more detailed I am about this now, the less likely I am to have a problem down the road. I also remade the tie down brackets. After fabrication, I primed them with the self etching primer in a can I bought for just such occasions. I was dismayed to learn however, that I do not have enough of the AN426 3-7 rivets required for installation. No worries. I will finish what I can and order some from Van’s. I have a list of other things I need to order anyways. (Like proseal for the tanks!)
