Tip: Installing Platenuts
 

Hi guys,

I had the pain last night installing some platenuts. This morning I searched this forum for tips on installing platenuts....and nothing. :(

So for completeness would you guys add/reference your platenut installation tips and photos here for others to find & use later:

Some specific Platenut questions from my side:
1) Is the platenut jigs worth it? Buy or make your own platenut jigs?
2) When to countersink and when to dimple platenuts?
3) I believe there is a special small head rivet to aid platenut installations (MS1097)? And
4) Apparantly Van's sell a flush head #40 Pop rivet to aid platenut installations?

Thanks in advance,
Kind Regards
Rudi

Rudi,

Are platenut (nutplate) jigs worth it? In my opinion, every penny. I have an extensive collection of such jigs covering a wide range of applications from a #4 screw to 1/4" bolt and use the jigs frequently. This tool virtually guarantees quality and repeatability when installing platenuts without undo difficulty. If you've ever had to drill out the pattern for floating nutplates (or platenuts...the term is interchangeable) one at a time without a jig you know what frustrating work it can sometimes be.
I've installed thousands of nutplates over the years (ex production worker) and I've never run into a situation...including the construction of my RV-6A where I had occasion to countersink or dimple a platenut so I cannot comment on that point.
Use NAS1097AD3 rivets to install nutplates. I think Van's may have coined the term "oops rivet" to help describe using an NAS1097AD4 rivet in place of a botched AN470AD3 in a hole brought up to size #30 since the head diameters of the rivets are about the same.
If Van's sells a flush pop rivet to aid in installing the nutplates...all the better. But in my experience the head diameter of such pop rivets is the same as AN470's. Remember that .032 is the minimum material thickness for machine countersinking and much of the material we work with is thinner than that. Van's does sell the NAS1097AD3 in a few lengths but last I checked, you had to go to "the list" to find them. The NAS1097AD3-3.5 is by far the most commonly used length.
I will take a digital picture or two of some of my jigs (perhaps alongside an applicable platenut) to help illustrate their uncommon utility and will post the photo's here later. Such jigs are available wherever surplus aircraft tools are sold and don't forget the Flymart! I got more than one example there for just several dollars each.

Thanks Rick6a, that helps

;)Suddenly a lot of talk on platenuts / nutplates on the forum. I'd like to consolidate some posts that have come up here.

Where to get cheap nut-plate drill jiggs:

Interchanging a #8 and #10 jig + nutplate specs:
When Countersinking - Use NAS1097AD3-x rivets w/nutplates:
When Dimpling - Grind the female dimple on one edge:
If you guys have more tips add them here...:p

OK,

I 'borrowed' this picture from yard store. Could you guys please say which styles to get for which type of RV, since I have not run into all the nutplates yet.
i.e. on a RV 7 get style x and style y since they are used a lot, on a RV 6 get style z and style y: (PS: I'm interested in the nutplates for RV7, but post the other as well if different for reference)



Thanks
Rudi

Hi Rudi,

99% of my nutplates were the dual lug #8. That would be the 518-B. I have also installed dual lug #6 and #10, but really very few. Some of these were for things I did that are not in the plans.

From time to time a single lug #6, #8, and #10 is needed. I don't recall ever installing a 1/4" nutplate.

Ah yes... but if even though most nutplates you use are dual lug.... if you buy the one lug nutplate jig, it will do both one lug and dual lug layouts, while the dual lug jig will only do dual lug ones.

Buy the dual lug one.... 518-H

The www.yardstore.com price is even identical!!
