Hmm, nothing inside my electric screwdriver moves up and down - it's a normal motor and some gears. It's a Black & Decker by the way. Now how to get it to move up and down...
I ordered one of those blemished SouthOrds by the way (nice price). When I get it, I'll tell you how bad it looks... (and how bad I stink at opening anything with it...

)

Many people believe that black electric pickguns are better than white ones. This is not true! It doesn't matter if you only have a small white electric pick gun - it's how you use it! You can have a big black electric pickgun and perform really poorly with it, while a qualified operator can achieve amazing results with a small white electric pickgun!
