Plans error?
Has anyone noticed this? On DWG 12 the plans show holes to be left open for the bottom skin attachment (first pic). On DWG 38 it's a different set of holes (second pic). The top skin holes match on both drawings but on the bottom skin, they are different. I suspect DWG 38 is correct. Or am I missing something?
Sorry about the orientation of the photos.
Also, if you didn't install the platenuts before the skin, how did you dimple the multiple layers for the platenut rivets? Will a squeezer and dimple dies make an adequate dimple for the screw and rivets?

Sahrens on the board ran into this on a day I went over to help. He also had QB wings with all the holes filled. He had noticed this error on the plans, and that his wings had some extra rivets, and was concerned. After stepping back and looking at it, and looking at my RV-6, he concluded that it's an error but not a big deal.
We drilled the extra rivets out of the wings, decided that the hole pattern wasn't going to match either plan, and moved on.

Thanks Doug. I should have done a search first. There is a wealth of knowledge here.
Moderators, feel free to delete the thread.

Some things just are what they are - this is one. They are a small operation to keep costs down and they use their people to answer the same questions and focus on making new planes.
This is just an observation - not being critical. I am just happy they answer questions pretty well, costs are low, and stay in business for future support.
Hopefully the 14 people realize this behavior and some enterprising person is gathering a list of defects to post/sell to future builders. 14 guys listening?

Delete the thread? Larry, I'm a bit behind you on the 7 wings and this stuff is really important. I get a few 'gotchas' from a local builder, but I wish there was somewhere we could go to find the occasional misleading plans and directions.

BUT if they just spent the time correcting the plans once and posting the revisions online, wouldn't the number of phone calls reduce allowing them to keep their costs down even lower and focus on making even more new planes?
My lack of trust in the plans after hitting the first gotcha slowed down my build considerably. Before I did anything I searched on VAF for errors and gotchas and I still got "Vandalized". I love my plane and I'm thankful that Vans is around but it sure would have been nice to hang my hat on the plans and directions.

I'm with you Michael.
This is a little one. I would love a gotcha page.
If I can help, feel free to e-mail.

Hi, Larry
I had not noticed the different rivet spacing in the plan`s. With respect to dimpling 2 layer`s the inboard skins are .032 and you could machine countersink them. Ask Ryan and see what he says.

Another option used by the early -6 builders was to use a small 0.032 plate/shim between the rib and the nutplate.
This allows a complete countersink for the #8 screw and lets you use the usual K-1000 nutplate instead of the countersunk K-1100 nutplate version.
Essentially the extra metal layer duplicates the -6 plans call out for the upper nutplates in the area of the wing walk stiffener plate.
