Riveting for speed

[Paul Copioli]

Yes we will use rivets. Interestingly enough, we have been using rivets for the past three years for the bumpers and an inspector never said a word until the Championship last year during elimination round inspection (yes, we even passed the initial event inspection). I am glad it is cleared up this year.

And it is a fact that I can remove a pop rivet faster than someone can remove a nut and bolt. I am taking challenges.

Do I get to use my cordless driver with a hex socket on it?

[Paul Copioli]

Yep.

[IndySam]

sounds like a good contest/fundraiser for IRI.

$10 for a chance to beat Copioli.

Last year Paul got to kiss the pig at IRI. Not that he, or the pig, actually enjoyed it.

I imagine he'd welcome the opportunity to prove his riveting speed at the next IRI, rather than repeat last year's performance. It could be called the Copioli pit-stop challenge.

we are going to be using rivets for the bumpers. see the attached photo for an explanation how. We will be using 1/4 inch aluminum rivets.

I might steal this. It's a good idea.

I feel like we should get karma points for "Inspiration via Q&A".

Greg I am intrigued with this idea.
Do you think we would have problem with the mount that sticks out from the wood bumper material?

In looking at the way R08 is written I see no problem with this.
The rule states that elements attached to the bumpers are part of the bumper so I can only presume that you can attach elements to the back of the bumpers that are not the "3/4" plywood...

I really like that the GDC has opened up these requirements this year allowing all of us to engineer our own ways of attaching the bumpers...

After all ... it is the bumper that is important and that they don't weigh more than the 18 pounds total...

Here is our cross section. I am too tired to make a special picture so here is a direct shot from our solid model. The total height is 6", the bottom of the large angle is riveted to the bottom of the frame and the flat part is riveted to the side panel.

very cool - we could use this too. I'll pass it on to the team for a vote. thx for sharing.

Our team has one that we think can beat this one in speed, and I'm curious if the think tank around here agrees.

Take two hinges, and mount each at the ends of a bumper, so the bumper does not move when the hinge is also mounted to the chassis. Once the hinges are mounted to both, Knock the pins out. Instead of the pin, put a bolt of similar size in, and spot weld a Nut to the bottom side. Removing the bumpers is as simple as hitting two bolts with a power impact tool from the top.


Though I can see this rivet idea being cheaper than ours....

Here's a question though Paul, do you guys have a pneumatic rivet gun? I can't see a manual rivet gun being faster than taking a nut on and of, though maybe that's just our riveting abilities(or lack thereof) in action.

[Paul Copioli]

Pneumatic rivet gun from Harbor Freight - $25

Portable compressor deom Home Depot - $60

The look on someone's face when your rivets are faster than their bolts - priceless!
