I talked to my friend John Sanizzaro today, and he is still using his wing jacks for a few more weeks, so I decided to go ahead and build my own. I figured out a really cheap way to do it after perusing several builder websites. These cost me a whole $6!! Ouch!
These are super simple. The rod is 12" 3/8-16 that is tightened right in to the wood about three inches down. I drilled the hole in the wood 5/16 so the threads would grab a hold, and not move. Easy enough!
You can see the leading edges in the left pic above. I removed those first in order to level the wings using the fishing line method per the instructions. Then I clamped the rear spars loosely with the tiny 1" clamps and some soft kindling wood and a piece of paper to protect the spar.
Then I brought some wing skins down to be fitted. W-702, W-703, and the doubler skin were cleco'd to the top of the right wing! Sweet!
Below you can see the doubler skin is lined up just about perfectly under the main spar.
With the wings skins in place, I tightened down the rear spar clamps to hold it all nice and secure. Now I have to figure out when the best time to hang the plumb bob is...
