Dimpling Nutplates

[Berchmans]

I use the die shown in the previous post in a hand squeezer...works great. Not hard at all...

Help me understand. The NAS 1097 rivets have a smaller head but they are still flathead rivets. How can you use them without dimpling? Or are you saying the dimples were small enough that you could accept the nutplates being slightly proud?

The 1097 - 3 rivets have a very small head, countersinking even .025" thick skin will not open up the hole any more than what is necessary for the countersink. Nut plates only need to be held in place to keep them from rotating, the small counter sink is more than adequate for this.

just stick them in a hand sqeezer and dimple the things.

Do we have to make every simple thing an ordeal?

Do we have to pick apart every post when someone asks a question? Maybe we should pick at spelling mistakes. Good grief is right.

I don't see any big deal about this. Everyone has their own practice. So what? I don't like to dimple a base metal, then dimple the nutplate when all I have to do is do a slight countersink with a deburring cutter to the base metal and nothing to the nutplate. Spin spin spin and its done. I would always use 1097s 1st and dimple as a last resort with nutplates. But, thats just me. Besides, too much squeezing gave me tennis elbow. Lighten up everyone. Jees.

It may be a simple thing were discussing here, but isn't it the whole reason were apart of a great RV community..... I`m going to order some 1097`s tomorrow and run with them. Thank`s for reply`s guys.

I think the point that I was making (apparantly not too well) is that this community seems to be suffering from more and more paralysis by analysis. I'm certainly happy to explore issues when they justify the analysis, but it seems that a lot of builders are over thinking every part of the build process.

i'm not advocating being uninformed, but a happy medium will lead the builder to actually spend their time building instead of thrashing forever on minutia.

I'm also equally sure that I will not changw ANY opinions on this among the worst offenders.

I built two RV's and made everything removable with screws and nutplates. At no time did I ever feel a need to dimple any nutplate which in my mind is a kludgy way to do things. Production shops routinely use 1097's in aircraft production, why shouldn't you? An archive search will reveal much information on the subject. Here is one link with images that graphically demonstrates the possibilities using NAS1097AD3 rivets:

Rick:

My RV-6 has been flying almost 15-years and has almost 2,600 hobbs hours on it. I, like you, did not waste my time or energy dimpling nutplates and I also used them everywhere something comes apart. Yes I agree that it is a kludgy way to do things by dimpling them.

I have not had any issue with any of the nutplates 15-years and 2,600 hours after installing them WITHOUT dimpling them.
