Well, you can say a lot about tool boxes, but if you’ve ever worked as flat rate mechanic, you’ll know the value of “a place for everything and everything in its’ place.”
This. I bought my current box and set it up to rape 10k services on Harleys. I had my process down to where I could pull three drain plugs and be done with the service by the time the oil stopped dripping enough to put the drain plugs back in. I have one tray for inner primary jobs, one for base gaskets, one for services, one for tires, and one for forks.
Most guys crap when they see how small my box setup is, but I don't have to root around very often. It also helps that I don't have to work on automotive or foreign crap which seems to change every damn year and they give little or no thought to the schlub that's gotta service the machine.
