Question about rivets and riveting....

Hi all,

I am a complete newbie to the world of riveting. I have to do some and I
know nothing about it.

It *IS* aircraft related, though not directly. I'd appreciate any help I
could get:

I am refurbishing a old P-series flight helmet. They had leather oxygen
mask tabs, with snaps, on the sides which were riveted to the helmet.

I have the rivets that one used back then but I do not know their
nomenclature nore do I know how they work nor what tool I need to set them.

I'll try to describe the, and I can snap a digital photo and email it if tht
would help:

The rivet comes in two pieces. one - the outside - has a solid head, and
the shank is hollow.

The mating part has a head that's the same diameter, but it's not solid. Yu
cna sight right down the shaft - it too is hollow.

the second part fits inside the first part.

You can see a photo of one on:
