One of the nutplates in the F-766A flap motor channel contains the 12,000th rivet of the project...

Letting a little long overdue sun shine on the project. It's 45 degrees here in southeast Michigan, but with the overcast melted away and the wind near calm, it was time to open the hangar door and enjoy a cool one (the criteria is that the day is warmer than the beer )


Not a lot of progress lately on the -7. My excuse (and it IS just an excuse), is that I've been spending a lot mental energy on the fact that my Cessna 170B is almost ready to return home. Some may remember that in the summer of 2014 '98C was savagely attcked by a renegade hand-propped Cherokee.


A slightly generous insurance settlement got the lions share of the repairs done, and kicking in some coin of my own got her a few upgrades, cosmetic repairs, and new paint and interior. 32 months later she's within a week or two of coming home. All she needs are a few touchups, a static system check, and a weight and balanceYIPPE!

Default I MUST have done something wrong...

...because things rarely work out for me as well as they seem to have for the initial fitting of the wings on my RV-7.

After plugging the wings into the fuselage, putting two 7/16 hardware store pins in each side, then clamping the rear spar fittings where they fell, we hung two plumb bobs off each leading edge and stretched a string along the floor. The sweep is within 1/8 inch all the way across. Measuring for square from the rivet in the forward outboard corner of he outboard main skin back to a point on the centerline of the aft deck just forward of F-711, the two sides are within 1/16 inch (out of 187-5/8). Checking incidence, both wings measure 0.1 To 0.2 degrees nose high at the root and tip, and about 0.3 degrees nose high midway between.

I cant help but think Ive done something wrong. Ive marked the rear spar bolt holes in the center of a 1/4 x 1/8 rectangle that will give adequate edge distance on all the parts, and will walk away until tomorrow when Ill clamp a drill bushing in place and remeasure everything.

Hi Miles,
I dont think youve done anything wrong, I think your numbers are excellent. A tenth of a degree will be unnoticeable and could be random variation. I bet even the temperature you measured it at could create tiny changes in the metal. At least both wings are identical in measurements and Im sure your plane will fly excellently. Id say drill the holes and build on!

Bruce

Good to hear from you Bruce!

Since that post I test fit the flaps, and the inboard end of the lower skins lacked about 1/16 touching the fuselage. I had about that much spar stub extending below the forks on both sides, so I bumped the trailing edges up that far, remeasured about a half dozen times, and today finally committed drill to metal. I have both sides up to 1/4, and will see if I can borrow a 19/64 drill bit and 0.311 reamer from one of several local builders who have done this before.

If I had known it was going to be this easy I would have done it some time ago.

Good help, and they didn't even visit the kegerator. (that might have something to do with it being 12*F outside...)

Inboard edge of upper flap skins need to be trimmed slightly.

Left side. Right side looks pretty much the same.

Default First RV-Grin From Inside the Future N904KM

I needed to remove the control column to adjust the stick angles, and couldn't reach it from outside the airplane, so I took the opportunity to document the first time sitting in the airplane.

Thank you Jereme! This should have happened 2 years ago. There is NO excuse for this airplane not being done, being retired and having a heated hangar less than 30 seconds from the living the room couch...

Heated hanger! Lucky! Man, that looks like great work!
