Bringing a compressor to competition is complicated. It is a black hole of debate.

There shouldn't be as much debate as there is; all the inspectors say "don't bring a non-robot compressor".

Care to cite a rule?

These aren't rules, but any rules I can cite won't apply next year anyway:

Right, they're not absolutely disallowed. A blanket statement saying "all inspectors" will ask you to remove a shop compressor isn't true. Some events will allow them, some will not.

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

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.

This is absolutely incorrect. There was NOT a rule in the books to forbid it. They can ask you not to run your shop compressor due to power concerns and you are absolutely not allowed to fill up your robot tanks from it. But there is NOT a rule saying it cannot be in the pits.

My those treads are worn. Good thing you know how to replace them, quickly.

Re: thread hijack to pit compressors -- at many events where I have volunteered, the people responsible for pit power want to know which teams have compressors. For example, at St. Joseph last year, we kept an inspector assigned to watch teams unloading and check for pit compressors. This was NOT motivated by suspicion that such teams might use pit compressors to fill pneumatic storage tanks before a match. It was motivated by a strong desire to keep pit power in service all the time, even if that meant juggling pit assignments so that the number of compressors on any one distribution circuit did not get too high. Fortunately, we did not need to move any teams or ask them to refrain from using pit compressors. I have been at events in past years where one or both of those things did occur.

Most of the pit compressors I have seen teams use at FRC events were rated for 15A current draw. That in itself is not much of a problem; however, many of these things draw much larger surge current when they start (I have measured up to 50A for a split-second) and THAT can push an already loaded distribution breaker past its trip point, knocking out power to a row of pits. Then the roadies have to scurry ...
