Pop rivet nails
Not to highjack the thread but after my initial supply of nails ran out using the pop riveter I couldn't find any suitable replacements. What nails are you using and where did you find them? I've checked HD, Lowes and Ace and so far am SOL.

It's been a while since I've done this, but it's never been difficult to find the nails. Just take your dies with you and find a finish nail that fits.
When you are dimpling, start with the air pressure very low and increase slightly until you achieve a good dimple. I can usually do an entire wing skin with about 3 nails.

Pop Rivet Mandrels
I threw away the nails from the getgo - not enough pulling force (IMO) before the head popped off. So I have used exclusively the steel mandrels out of pop rivets that best fit the holes in the dies & skin. These mandrels are designed with a "frangible" stem - it breaks at an engineered axial load, and is (within manufacturing limits) repeatable. The breaking load is much higher than any nail I could ever find (maybe some hardened ring shank nails would work - just never tried them), and there was always a ready supply as close as my rivet assortment. On -4 holes I opened up the holes in the dies to accept a larger mandrel in order to get more "pulling power" - in some instances you don't need to break the stem to get an acceptable result, and you can keep using the stem/die combination over and over again until fatigue takes over and it finally breaks.
I "harvest" a selection of mandrels ahead of time and keep them with the die sets for ready access when needed.
YMMV - but I'll bet that if you have "gone over to the dark side" and used these mandrels for this purpose, you won't go back to nails anytime soon!

**Edited for clarification***
I have used both pop rivet dimpler and used the rivet gun/bucking bar with squeezer sets.
I preferred the shape of the dimple made by the gun/sets over the shape by the particular set of pop rivet dies I had. (maybe they were not the quality that Mel used) They did not make sharp dimples and the heads frequently stood a bit proud.
Turn the pressure way down on the gun and take it easy to prevent putting a "smile" in the sheet.

I missed those same holes.
What I did is:
I have a very heavy bucking bar (steel) that is about
10" long. (You could use any big piece of steel).
I drilled a hole for the female dimple die in the end.
The I pulled the shaft out of my c-frame dimpler
and put the male dimple die in it.
I held the solid bar inside the plane while my wife lined
up the part outside, and I pushed up against the
skin while she whacked the c-frame shaft with the
hammer.
That way they came out just like any other c-frame
dimpled hole.
I do have pop-rivet dimple die tools. I am not sure if mine is
a 3/32" or 1/8" though, and although I've used it before
and made good dimples, I wanted these holes to be
dimpled as well as possible since they would be very
visible and they hold the seat belt bracket.
I think the pop rivet tool will work fine too, and you can
always start with that and change your mind if you wish.

Thanks for the replies.
RV14 builders - revision 0 page 10-30 step 1 should include #30 holes

A Rev. 1 version of Section 10 was published to the Van's web site on 10/17/14.
A revision that addressed this issue was part of that update.
All builders that have e-mail info registered with Van's should have gotten an e-mail notification about the update.
The Section 10 update can be accessed HERE

With a helper, could you use a "C" frame dimpler?

I want to start building an airplane again JUST so i can use old mandrels in a pull rivet.
This is one of those tips that's so obvious, I never thought of it.
Great suggestion.
