Having taught apprenticeship for years to the sheet metal workers local Union apprentices, one of the things I have found is the importance of teaching the ability to think in steps involved. Too many times one grabs tools and has a go at things, only to have to back pedal along the entire way, causing not only time wasted but possible damage and do overs.
A good mechanic with mechanical aptitude will first go thru all steps in his head, countering each step with “what could go wrong if I first don’t do this” and then once that is figured, moves on to the next step.
We use to teach service technicians for their first two years of apprenticeship hand layout of sheet metal fittings. Everytime they would complain and ask why they needed to learn sheet metal layout when their career is mainly electrical troubleshooting. I told them because hand layout teaches you the basics of approaching a task in a series of steps, methodically.
I’m quick to spot someone who lacks mechanical aptitude by the way they operate, like each time leaving to grab a tool, lacking having all supplies needed for the task, and having to constantly dismantle parts because steps were missed. Excuses stacked upon excuses to make up for poor performance.
That tells me either they’re “winging” it, or they just haven’t given it much thought. When you ask them what their plan is it’s typically a “well, uh, I guess I’m gonna do this” vs the guy that’s went over everything in his head long before the task came about and already has “the plan” itemized out in steps.
Lastly- tools. A mechanic is only as good as his tools. Use poor quality or the wrong makeshift tool for the job and that slows you down and causes you to take short cuts. The guy that preaches the use of the BFH or grabs a vice grip instead of the correct spanner wrench, well, they don’t impress me one bit.
Oh wait! One more important thing! What about pride? Pride knowing you did it right, in good time, THE FIRST TIME, with the least of mistakes, and turning in a product worthy enough to hang on a wall, or even sell? That’s what I’m talking about
