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 ________________________________ Message 2 _____________________________________ Time: 09:36:39 AM PST US From: "Scott Aldrich" Subject: RE: MurphyMoose-List: Rivnut dimples for access covers 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. http://www.aircraft-tool.com/shop/detail.aspx?PRODUCT_ID=5102D-1%2f8 &ReturnPage=/shop/flyer.aspx?PageNo=2 Scott _____ From: owner-murphymoose-list-server@matronics.com [mailto:owner-murphymoose-list-server@matronics.com] On Behalf Of Ted Waltman Sent: Monday, October 02, 2006 10:21 AM Subject: MurphyMoose-List: Rivnut dimples for access covers Below are two pictures of access covers that I have where they have been dimpled for rivnuts.

Ted ________________________________ Message 3 _____________________________________ Time: 09:52:24 AM PST US From: "Ted Waltman" Subject: RE: MurphyMoose-List: Rivnut dimples for access covers 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.
