Greetings:
Rebuilding is not for the faint of heart. So many choices along the way. I wanted to follow someone who really knew the aircraft and not be one to blaze new territory. Basically I have followed Eugenio's suggestions and recommendations whenever I could. He has been extremely generous and everything he has done seems to be based on careful analysis and consideration. As I move closer to actually getting the aircraft in the air (hopefully a few more months), it is clear Eugenio knows his stuff. So... I took everything down to the wood and covered most of the wood with a very thin coat of fiberglass. The fuselage and wing fiberglass jobs have been posted. My goal in this post is to bring many of those issues together and add the fabric and painting since I am using the Superflite urethane system for certified aircraft. The finish coat is going on in the next few days, but I thought you might like to see the primer stage. I added those images to the last album, and I will add more images to that album as the painting progresses. I have used PolyFiber materials on other aircraft and they are fine... but I wanted a higher gloss and harder paint surface (but still with the flex properties) than the vinyl. Anyway, just go to the last entries on the album to find the most current images.

Ok Colin, time to get my engine on the stand and work your magic. We'll have pictures of the engine soon.
Cheers,

Bob, thanks for bringing us along on your adventure, great pictures and great looking work! It makes a lot of sense with extra draining grommets and your trailing edge looks fantastic. It looks as if you moved the outriggers further out towards the wing tips, please consider that when you cut your outriggers to length. In this thread we discussed that:
http://sbeaver.com/cgi-bin/fournier/cutecast.pl?session=bP027TjRPSY7XhuGyGTT8um7cf&forum=11&thread=527
I think Eugenios way of expressing outrigger length (clearance of the "high" outrigger) makes a lot of sense, but then again as you remarked a lot of what Eugenio says makes sense. Please keep those pictures coming, they're a great asset for all future Fournierism.
May the 4's be with you/ Jörgen

Now that you have the wing painted white I will give you a tip to do the wing walk easily and nicer than the old way. First trim with painting tape (plastic tape) the surface you will paint; mask the surface all around; when you are ready put a paper tape to make the painted surface about 5 mm narrower; at this point spray a heavy coat of the same product you use for the finish (I usually do the wing walk the same colour of the aircraft, blue, red or else, but you can do it black or white or else as you like) do not worry if the paint sag, go heavy; now take some sand (yes sand, the one I use with cement and lime to build walls) and throw it over the painted area; don't be scared, throw some more to cover the surface, then roll the wing to let the surplus go away; now with the wing horizontal, remove the paper tape (only the paper tape, leave the plastic one and masking paper) and spray again a coat of the same paint in order to fill the sand and have the edge painted too; remove all masking and let it dry.
With this system your wing walk won't unglue (the self adhesive one) won't fade (it is the same colour also below the sand) and won't loose the grip properties, plus is watertight and very easy to be washed.

Gorgeous, Bob. Smooth and shiny. I'm very, very jealous! Can't wait to see the fuselage.

Hi Eugenio: Actually the finish coat has yet to be applied... what you see in the album is the primer coats. Regarding the walk area, I did two layers of fiberglass and also continued the Dacron from the wing area to the cockpit... perhaps it is overkill, but I wanted it to have a bit extra surface coverage. I learned about the sand when I visited you and thought I would try it as your aircraft looks so "finished." Thanks again for the reminder.. it is a wonderful solution to the walk area. Bob

Greetings... OK, the wing is painted and looks great. It is safe in the hanger waiting for the rest of the aircraft to get painted. I added a number of pictures to the ongoing album. There is no question in my mind that my painter really knew what he was doing and if I had tried to do the paint, it would have looked like a first paint job. Thought you might also like to see how he did the masking. The other aircraft parts are going to his shop in about a week... more sanding and of course fabric on surfaces that need it. As you can see, we ended up doing the whole aircraft. More later, but we are very happy with the wing.

Looks great. You mentioned in one picture, that you will cover it with plastic?, I've been warned not to use plastic for protecting the wood parts, strong paper will be better, it will breathe and there is no problems with humidity

The wings look great, Bob. I would also not recommend putting plastic over it. It's going to be out-gassing for a while and it could do nasty things to the surface if covered with anything. I would say just hoist it up in your hangar and let it get a bit dirty while it fully cures -- and just clean it off when you're ready to assemble. It's going to spend the rest of it's life getting dirty and washed off.

Thanks for the advice on not covering with plastic... you guys are right, it is going to be left out anyway and washed once in a while... so not plastic cover. More later. Bob Brock

Here are the latest pictures... the fuselage is back in my hanger ready for the panel, engine, interior, etc.
Dann Parks was generous to provide me a copy of his tracings for the RF-4d trim... it is a little different from the original in that the top red strip is a little below the cockpit opening. Also, I believe the original N numbers are too large for such a small aircraft so I left room for 3 or 4 inch numbers.
Collin is rebuilding my engine... I consider my self extremely lucky to have so much help in this project. Everything Eugenio told me is completely accurate. I have shamelessly taken all the ideas, suggestions, parts and recommendations to incorporate in this rebuild. It feels like a mile stone.... thanks to everyone.... more later.
Again, the new pictures are at the end of the album.

Spectacular job, Bob! That glass-smooth finish looks fabulous. Can't wait to see it all assembled. And with Collin's engine, it should perform well too. Can't wait for next spring/summer when they get airborne.
