| Subject: | Rivnut dimples for access covers |
Below are two pictures of access covers that I have where they have been
dimpled for rivnuts. I've looked all over the web and can't find any tool
that creates these large dimples for rivnuts. Has anyone on the list seen
such a tool to create these rivnut dimples or is this some totally custom
deal that someone made?
Thanks in advance...
Ted

Ted, are those dimples "up" (is that showing the "top" of the cover?) so
that they can sit over the protruding rivnut?
Maybe just a large dimple die set
http://www.denunzioracing.com/shop/denunzio/dimpledies.html if they are
bigger than the more standard aircraft ones
http://www.aircraftspruce.com/catalog/topages/dimplekit.php
Those are pricy - these are the cheapo ones (which would be hard to pull in
that thick cover plate) but probably too small anyway.

Yes, with these dimples the access covers sit totally flat. Had to be some
squeezer set that someone custom made I guess. I'm surprised that there
isn't some common "aircraft" set out there. Seems like a great idea that
would be relatively easy to do.
I had some friends suggest just drilling a recess in a block of flat steel
then use that recess to hit the plate with a hammer and punch. Might work
but prob not as I think the whole plate would just tend to bounce meaning
one wouldn't get a clean dimple.
Another friend said just put the plate on a large washer and hit it the same
way. I suspect it too would be a poor result.
One can purchase a flange tool to have the center section of the plate flush
with the rivnut(s) and the very edge of the plate flanged to be flush with
the surface (e.g. wing, tail, whatever) as I'm told Cessna does. I don't
like that approach.
Maybe I can talk a buddy of mine into machining me a custom dimple set for
the squeezer I have.
Thanks for the links. I'll check them out too.
