The entire skeleton structure, internal surfaces of skins, and skin laps will all be primed. Right now we are doing exploratory surgery, spot cleaning and priming mating surfaces in critical areas.

Save that wing skin with the shadow of his original registration number for him....he'll want it as a "wall hanger" art-project. :wink:

We are saving the skins for Paul. I'm trying to think of ways to make attractive hangar decor from this stuff

Are there two buckled ribs in this photo, or is that an illusion?

600+ hours working on a set of these gave me great appreciation for wing structures...

Yes it does Miles, and attention to detail :D
These wings had been sprayed with LPS3 or something similar. Whatever it was protected the surfaces very well, however it did not weep between the mating surfaces. There was corrosion between mating surfaces. Most of it is very minor. Very few parts will be replaced. We could probably clean up and save most of the skins, but the cost of sheet aluminum and labor to duplicate a skin is very little extra $$

I had my 170 treated with ACF 50 when I first moved to the Mississippi Gulf Coast. The stuff ran out from between the skins for years. I was only there for 6 years, hopefully the ACF 50 penetrated the faying surfaces....

Exactly what I would have done if I had them down that far. Will you use the old skins as a template to predrill the new ones?

Yes Miles, we will use the old skins as templates. These wings had a small symmetry issue but the washout was near perfect. Sometimes when we get wings that have been repaired before, we can't use the old skins for templates. In that situation we have the skeleton in the jig and back drill everything.

Ok, boys and girls I knew there was a graphic somewhere of the abomination done long ago,to 83c's tail. I am in Mena and found an old 337' in the paperwork I sent with Del. While Ryan's pic is ugly, I think this one takes the prize for ugliest wart on a 170.

OMG! WHOSE...signature is on that abomination!?

Ya gotta wonder why they didn't simply put it on the top of the fuselage or on the belly!

But...

One of my many "firsts" to do to it is to yank it off and put a beacon on the belly.

Ryan... why don't you just get rid of it and install piggyback strobes on the wingtip nav lights and be done with it?

[quote="gahorn"]OMG! WHOSE...signature is on that abomination!?

It was signed by a Harold White from deep in SE Texas who rebuilt it after a ground loop in the late 60's. Hence the 17HW it wore for years. I never really gave any thought to getting the original number back till we got the third coat of paint off and there were the original numbers.

Thats what the last owner before me did. Mounted the same little strobe on an inspection plate on the belly.Not near as ugly, and a lot less work.

Should have posted these first, before the previous post. These were taken during after clean up and primer. In process. Just getting ready to start installing new skins. Some piece parts haven't been primered yet. The camera flash and shadows plays tricks with the color
