How to: Bench Focus. Okay okay, so I feel like a newbie for asking, but I've never been taught, and I feel like no one at my school knows how to do it. I just "made" 10 instruments the other day. And I'd like to know that they left my hands correctly calibrated. Okay, let me explain my I say made. My tech. program is under funded, yet I feel like we unnecessarily purchase new instruments when we can't easily use we already own. So I spent an hour playing god, and throwing together a bunch of instruments laying around. There were a variety of problems, from faulty wiring, missing screws, and a fair amount of dead lamps. I was dismayed when I found out the "problem" in two instruments was no lamp at all! Well I'm still looking around for a couple of machine screws and I need to take a look at the wiring in a couple before I add a couple more to our roster. Anyways, I wondered what the general procedure was for this. Myself, and two friends, basically just made sure the instruments would turn on, had shutters that worked, yokes, c-clamps, lamps. I admit basic stuff, but it's not like anyone else was doing it. How should we go about bench focusing these instruments before they leave elec. storage *cough* fire escape stairwell *cough*. Any help would be greatly appreciated.
