Missed dimples
I failed to dimple these 7 holes in the .025" skin for 1/8" flush rivets. Is using the pull die mandrel with pop riveting tool the only option? Will a bucked female die and the male die in the rivet gun do the job without damaging the sheet?

I'd probably use the pull rivet mandrel.
If you are careful you can get good results with them. -Dan |
I have bucked a female die and used a rivet gun with the male die, HOWEVER, it is very easy to mess up the AL sheet with that technique. If you choose to do so then practice with scrap material A LOT. Otherwise, the pull rivet technique will be adequate and much safer. Just my 2 cents.

Another vote for the pop rivet dimple tool

I made , but I think you can buy a metal punch /holder for the dies. A friend holds the female die inside while you strike the male die holder with a hammer. Keep things square to the skin and make sure the dies do not slide on the skin.

I have successfully done this with the rivet gun as well. They key to doing it -- that I have found -- is to turn the pressure down with a regulator and use very short bursts.

Avery has a special rivet set and bucking bar just for this purpose, but you could also drill a hole in a bucking bar to accept a dimple die.

I have used the pop rivet dimple tool many times. No real way to mess it up.

I've built a few airplanes. I've used the pop rivet dimpling tool exclusively. Never had an "extra" hole. Never had a problem.
