An alternative to using Rivenuts are nut plates. They come in all shapes and sizes. Aircraft Nut Plates | eBay
In my younger days as an electrical apprentice I did my fair share of switchboard (industrial) manufacturing. Rivenuts were used extensively and even with good quality tools didn't always set properly, and a real pain to replace.
Now that I'm building a metal airplane I've discovered the world of nut plates.:D

Never seen them before Ron.
How do you use them??? Looks like you pop rivet them in place.

Hi Andrew,
Yes, you can use pop rivets, although for most aircraft applications solid rivets are used.
In this thread In need of Nutplate 101 - VAF Forums there are some pictures of nut plates being used and some hand tools to help with the holding of the nut plate while your riveting them in. The tools make the job easier but not really required.
This chart covers the common types: http://www.gen-aircraft-hardware.com.../nutplates.pdf
Not normally found in the aircraft aisle at Bunnings...:p Aircraft Spruce have a good range of hardware. Anchor Nuts from Aircraft Spruce
Speaking of which, I need to rivet quite a few to my wing spars, will be used to attach the fuel tanks to the wing...:eek:

I've often used similar practice in the past, ie make a plate to go behind/inside with tapped holes and pop rivet in place and may use this method again. Nutserts are so convenient though.Quote:

there is a cheap way to put in riv nuts aswell, use a bolt that matches the thread in the rivnut, and 2 washers, and a nut the next size up,
place one washer over the bolt, then the nut the next size up, then the washer, stick it into the hole u have drilled ( need to drill the hole perfect ) then use the nut to keep the rivnut square to the panel and tighten up the bolt,
I worked for a truck building company and we had to share one nutsert gun around the factory, so we just did it our own way most the time
Another alternative for smaller sized nutserts:

For small fasteners you can get threaded pop rivets. King Klik and Marston both used to list them. They used to go up to No.10 - 3/16". Very convenient for sheet metal work up to 16 gauge. A steel threaded mandrel is screwed into the threaded rivet and the rivet set by normal means. The mandrel is then unscrewed and you have a thread ready to accept a fastener.

Hi Harry,
I'm building a Vans RV 7A and am a member of SAAA Chapter 24. Next weekend there is the state fly in to Denmark airport hosted by Ch13 (the Albany guys).
Cheers
