Peter.

Get some of each size. You will always need them. Moreso the 1/4 and 1/2 inch size. Remember, the length is "grip length" and not physical size. A 1/4" grip range is more like 5/16 to 3/8".

Use "aluminum" rivets ONLY.

Are Olympic rivets all the same diameter? Is there one single type to purchase. I looked online and there seem to be many types available. I'm assuming one should buy a variety of lengths.

"DO NOT USE" any fractional or letter size drill bits.
This one I'd like to understand.

Looking at recommended bits vs rivet size:
#30 (.128) for 1/8 (.125) rivets.
#21 (.159) for 5/32 (.156) rivets, including Olympic rivets
#11 (.191) for 3/16 (.188) rivets.

It appears 3 thousandths oversize is the ticket. But why? Is the oversize simply to facilitate getting the rivet in the hole? If so why not use the smallest hole that meets this criteria?

Or is there something about having a hole just a tad larger than the rivet?

interesting article on Drill bit sizes in Wikipedia

Bryan,

The drill sizes come from military specifications for buck rivets. The latest spec is MIL-R-47196A(MI).

When bucked rivets are properly set, they expand to completely fill the slightly oversized hole.

Olympic rivets and pop rivets, on the other hand, act by clamping two sheets together, without expansion of the shank.

I believe that the hole sizes for buck rivets got "inherited" by the blind rivets, and that is where the numbers come from.

Personally, when installing pop rivets I just use the rivet size; 1/8" drill for 1/8" rivet. I never use Olympic rivets so I won't comment on the correct drill size. For bucked rivets I use the number size drills you listed.

Edit: Further research on Olympic rivets indicated that the 5/32" Olympic uses a #20 hole (.162-.167). That comes from http://www.boltproducts.com/marson/b...bulb-tite.html ,near the bottom of the page. So there are lots of choices for what size to use.

Contrary to beliefs, without "EXTREMELY" accurate and expensive machinery, drilling a "round" hole is almost impossible, even with a 30,000 RPM air drill, such as we use, in the soft aluminum that Airstream uses.

Therefore if you use a drill bit slightly oversize, the rivet will enter the hole with ease.

If you use a 1/8 inch drill bit for a 1/8 inch rivet, you will find that you have to force the rivet into the hole.

But again, to each his own.

Andy

Sounds like the reason for the .003 inch larger bit than rivet to to make sure that the rivet fits without binding yet without providing too much slack for it to slop around in after it is crimped.

I guess the reason for non binding insertion is to avoid stresses on the rivet or the material that could weaken the rivet or its grip or the material. Not too much slack is then to avoid working and to provide maximum grip surface for the pop rivet.

The round hole issue has implications to think about. 30k RPM sounds like a
dentist's office. Soft aluminum is at least easy to work with.

If you put a micrometer on most pop rivets, you will find they run a few thou. under 0.1250". I don't have to force pop rivets into the hole.
