...you can tell a good "classic" bike mechanic from how many "tool" divots are in the cement floor of the garage. Creating a good divot takes practice, and the size of the divot is directly proportional to the tool size, i.e. a Craftsman 10mm open end leaves a smaller divot then a 14mm box end Snap On. Also, when creating the "divot" the tone the tool creates when it strikes the floor has bearing on the total divot score. A loud "ping" is not as good as a long "ringing" tone, followed by the classic ricochet sound as the tool bounces off the floor, and then into a newly painted gas tank, finally ending up under the workbench.Getting the mechanical skills is easy. It's learning to throw wrenches properly, and invent new swear words is the real trick. Working on old bikes will have you doing that real quick, so you need to learn proper form and technique to look like a real pro. To start out on a good note, find any 25 year old Japanese motorcycle that has been sitting outside for the last 20 years and try to remove the engine screws from it. That should start you out right. Then graduate to finding old Harleys and try to stop all the oil leaks. By then you will have all the wrench and tantrum throwing practice you need to hang with the best. Good luck!
