If you're doing sheet metal, I can see how it would be a real pain to have to do all your rivets manually. |

It's certainly meaningful quantity, and it's certainly worth it. The time saved is huge. I like to think of labor in terms of minimum wage. If the cost of a tool saves enough labor that it's "making" more than minimum wage, it's worth it (as our kids make well above minimum wage when they're out fundraising). The flipside is true too... any fabrication we do that "saves" less than minimum wage is a bad decision, and should be a COTS item. Too many teams work themselves for below minimum wage. |

If we save some amount of time on our preseason drive chassis (say, an hour or two) by having a pneumatic riveter, there is really no feasible way we can readily turn that hour or two into money given the constraints of our team structure. There are a lot of assumptions implicit in the utility calculation you've outlined. Those assumptions are valid in some contexts, but certainly not universally. |
Re: pic: new shoes
We bought the Harbor Freight riveter right before our 2014 season to save us time and energy... and broke it almost immediately. We ended up just getting another hand riveter and using two of those. Ate up a LOT of time in build season though - with the amount of rivets in the claw we probably consumed more than 1 build meeting total in extra time wasted.
That said, hand riveters get the job done just fine. With practice we could do things like change claw parts (drilling out at least 12-16 rivets and replacing them) in just a few minutes. |

I was trying it yesterday and it wasn't working well at all, however out hose was leaking a lot so i think that was the direct cause. Once we fix/ replace the hose we can see how it works!

Re: pic: new shoes
Stephen, were you using the small yellow compressor directly or hooking it up to the wall-mounted air line? Send an email to Drake/Laverty to get a replacement host once you find the leak.
I'm not sure it's worth it to bring a compressor tank & air rivet gun to competition just for tread rivets, so we'll have to see what else we can rivet this season if the air rivet gun works so well we decide to go that route. |

Re: pic: new shoes
After some testing we found a large hand riveter (the style typically used for large rivets) worked better for putting nitrile on aluminium wheels than a air riveter. It allowed us to put a lot more pressure on the rivet when setting it compressing the tread around the rivet to create a secure attachment.

And some events will not allow them because teams MIGHT use them to fill up their air tanks??? |
