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!)20131104-144515.jpg

Here is the 50′ of conduit I bought from Van’s for the wing wiring.20131104-144529.jpg

Here’s where the conduit will go.  I’m not installing it just yet though. 20131104-144704.jpg

Here is my next task.  The wing walk doublers…20131104-144803.jpg


So tonight I used the Bullock Method for wing jacks to support the spars from sagging on the stand.  The Bullock Method, as I’ve named it, is pretty simple.  A couple blocks of wood and a long bolt make a very quick and effective adjustable jack stand.  I refuse to buy stuff if I don’t need it, and this was no exception.  I had most of the hardware laying around including the wood. Its even easier if you have your dog do the work!20131028-194344.jpg

Here is the result. 20131028-194356.jpgFinally, I ordered some parts from Van’s Aircraft.  I bought the replacement parts for the tie down brackets I messed up, 50′ of conduit, and the proper screw eyes for the tie downs.  Hopefully it will arrive before the weekend.
