Question about rivets and riveting....

[gregg]

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:

Thanks

Jesse,

Yes I saw it. But I probably should have been more informative in my
original email:

I cannot use that to set the rivets because that would be on the inside of
the helmet where I can't swing a hammer.

So I'm hoping there is another tool that can be used to do the job. I've
seen "rivet squeezers" but I do not know if they work with these sorts of
rivets.


thanks for your answer

Is the only way to put the rivet in to put the punch (part that is
hammered) inside the helmet? If not, see if you can put the other tool
half (anvil?) on some kind of protuding "real" anvil that is inside the
helmet?

This isn't a snap, right? I'd think it wouldn't matter which rivet end
goes inside the helmet.

Hi John,

Yeah it's the only way. It would look horrid otherwise. One end has a
smooth head - the outside part.

But the part you place the punch against is shaped kind of like the business
end of a trumpet though the "bell" is flatter.

That's why I was wondering if a "rivet squeezer" would work.

Well, I guess you could try something like back riveting. In this case,
put the punch in a vise or something that can hold it steady and upright
(trumpet shaped end up), with the far end of the punch resting on
something hard and solid (chunk of steel, or the vise shaft), slip the
helmet over the punch and position it, and use the hammer to wack the
rivet anvil. Would probaby be a two person job.

This isn't an aircraft rivet, it's a sewing rivet, used in clothing and
upholstery. (and flight helmets) So, you're in the wrong newsgroup for
experience in setting these things. I'd check with a local seamstress or
tailor shop, or the local arts and crafts leather belt maker, who can
probably set them for you for a couple of bucks. I remember a g/f who
used to work in upholstery telling me about these things.

But it seems to me that you could set it with an arbor press, fitted
with a concave swager so that it doesn't deform the head, and an
appropriate block on the backside.
