Mike- The wings will be close, but I have to re-do the color coat. It came out "orange peel" in appearance. I think I will try something different on the other wing, to find out what went wrong. Then I'll re-finish the top coat. I do see your point, also relative to the discussion on VG's the last few days. I am new to this, so everyone keep teaching me and forgive my errors. I talked my wife into buying a new digital scale for the "bathroom". At my age, I'll have one of my grandchildren tell me how to use it. I ground and fitted threar attaching lug. It now fits the factory u-joint. Looks good, works great, lots of meat on it- more than the other wing set.

I've done the same thing! Works great! At the hangar where I didn't have a compressor I used a spare tire for the propellant.

I mounted up one wing per instructions from Dennis at TNK. The only change I made was to fabricate a forward wing adapter channel, to make up the 2 1/2" difference between the airframe wing brackets and the wings that are being fitted to the plane. I chose to make the channel instead of using structural channel. Structural channel has a sharp outer corner, and a tapered flange. The sharp, squared corner would not let me get a flush, uniform fit to the old bracket welded to the inner steel rib. I did not like the tapered flange of structural- it could start wearing unevenly on the bolt, and the thin part of the taper was where the load was. I heated and formed a rounded edge channel 2 1/2" wide x 2 1/2" long with a 1" flange, made out of 1/8" hot rolled flat stock. Three 5/16" bolts secured it to the wing bracket, and when the AOA was right the last hole for the wing pin was centered nicely on the other flange. I did have to run a rope out to a tree to hold the wing for marking- the wind was erratic today, and kept swinging the wing back.
The wing folds right back, but the wing holding bracket supplied by TNK was not lined up with the new wing's holding tube. The wing's tube was about 9" to the rear, actually past the end of the fuselage main tube. I took some flat stock and made a couple of "J" brackets. I welded a 1/2" nut to the back of the upright of the "J", and cut a piece of 1/2" threaded rod to go through the holding tube. I padded the "J" brackets with some rubber moulding held on with plastic ties. Slide one end through, spin the other "J" bracket on, and set the wing in place. It takes about one minute to assemble, and gives me a lot more ground clearance than if the wings had fit. No flying weight added, either. Prop clearance is now about 3" from the aileron. I had to order a couple of longer aileron control tubes from Travis at TNK- mine were about 2" too short.
All the snow finally softened up to the point where I could clear off the tarp on the other wing. It is in my living room, and the patches are fewer and smaller than the first one.
The Pre-Val spray kits are $4.99 at my local NAPA store, and I picked up a laser digital thermometer from Harbor Freight for about $40.00. Works great.
So far, so good.
