James: I'm an ME with a little EE experience. I recall my early EE labs in college where we would get together in small groups (three typically) and try to solve the lab problems. I was not so hot on doing the EE analysis needed ahead of time to design the experiment, but when we went in the lab to actually do it, and had to go to the parts crib and draw out the components needed to set up the experiment, I was the guy who could take the circuit diagram we devised on paper and assemble the actual parts on the bench. Can't explain how/why that was. And yes Gordo: I used to be able to tie up a wire bundle with waxed ribbon PDQ. But I can do tie-wraps even quicker. And back in the day, the chassis we would get out of the electronics shop at the Lab for one-off equipment manufacture were works of art for lacing and wire routing. Those guys really knew their stuff.
