Re: Riveting for speed
 

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.

Re: Riveting for speed
 

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!

The look on Paul's face when for some reason "they" won't let him bring his compressor into the pits - PRICELESS!

... for everything else, use the "Big Daddy". (See McMaster #90239A510 - Best $100 our team ever spent.)

Instead of Robots racing dean kamen.... how about Bumper races?

Our Cotter pin method might be able to rival the speed of rivets, but I doubt it.

Drop in bumpers with bolts sliding into slots in L bracket aluminum, fastening with wing nuts? Design courtesy of 1114's 2008 robot. If you factor in the time it takes to set up the rivet remover tool (whatever that may be), we might have you beat?

I'd like to see the rivet method in action...

I'm pretty sure any of the previously mentioned methods will be under 10 minutes, but if this competition results in someone having to kiss a pig again, let the games begin!

Re: Riveting for speed
 

Our cotter pin method takes 2 people 1 minute tops to do a robot, and probably 10 seconds per bumper.

I imagine riveting is even less than that.

Re: Riveting for speed
 

Seconded on the Big Daddy. Accept no Harbor Freight substitutes. (That we can't really use it on the C-Base (after a wonderful experience riveting the Kitbot last season) is my only real grumble about the new frame...but we'll figure out a way to get our money's worth this year.)
