Hi all,
As the saying goes ... long time reader here.
I've started building an RV12 a few weeks ago (uk builder) and so far have been having fun but now I find I need some advice.
I came to do the skin nutplates on the empennage (page 06-06) where you have to dimple the nutplates but I'm not sure I have the correct ones, mine have thinner flanges on them.
I noticed that the nutplates I had looked slightly different when unpacking. Luckily I had another build available when I set the other different ones in the spar (he confirmed they were fine and that vans probably changed them since doing the drawings) but now I don't want to continue with the K1100-8 ones until I know they can be dimpled safely (and have enough strength with the thinner flanges on them).
I took some pics (below) to show the ones I have. hopefully this shows the issue of dimpling the rivet holes in the flanges of these (not much metal to dimple on them).
Being new I had to work out which nutplates were which by counting them in the packet as they looked different.
The nutplate and dimple instruction
Close up of the K1100-08
The other nutplate that was different (although I'm happy using this one as it has more metal rather than less).
Both of the ones that are different to the drawings
Is it possible that when packing them the sorter got the flanges mixed up. So the K1000-3 ended up with the flange type expected on the K1100-08 and visa versa?
The main question I have though, are these safe to dimple and use or should I be requesting new ones from Vans.
