There is a depth gauge for Cherry Max rivets that can be used...

To be honest, I wouldn't mess around with this one. I would kick myself, throw some things, then move on and open it up and install the rivets. That part is too important.

My 2 cents...

Why? A Cherry Max is a full-strength rivet (unlike some other kinds of "pop" rivets).

I'd use Cherry Max rivets and avoid the risk of messing up other parts drilling out all those rivets on the skin. I'd bet dollars to donuts that Van's says the same thing...

Did you already put the ribs on the top/bottom? you can fit your arm in there and buck those rivets if the rib isn't on, it really isn't that hard. Its easier with two people, but you can do it with one.

You dont have to take the skin off, just the rib.

Cherry max rivets are stronger in sheer, but weaker in tension. I've read elsewhere that certain manufacturers forbid cherry max rivets in this sort of application, where they are loaded in tension. For what it is worth, I had a couple of rivets with cut heads in this location (my first part), and later went back, removed enough rivets to peel the skin back enough to allow access, and replaced them. An easy and satisfying job.

I agree.
Four maybe. Eight drill the rib or skin.
If you haven't drilled rivets, search for tips and practice first.

So now a somewhat more serious question...how are you missing these steps? This sounds like something of a *process* problem which you may need to address, lest you get further into the build and miss other steps which are harder to correct.

Granted this is a -10, and I built a -7, so I don't know how the instructions are laid out for yours, but just a suggestion to figure out *why* you missed these...
