An easy way to make your 'helping hands' thing 100x more useful for soldering, gluing, and many other things. I'm a little embarassed posting this cause it's so simple, but people seem to be surprised when I show them this.
Step 1: Switch the magnifying glass with one of the 'hands'
The problem with the helping hands when you buy it is that the alligator clips are too far apart to hold thing really close together. Just unscrew the magnifying glass, unscrew one of the alligator clips, and switch them (or just do away with the magnifying glass, I never use it).
Step 2: Add a third hand
if you have a second 'helping hands' or just the necessary parts, add a third hand to the thing.
Or, make a third hand as seen here:http://www.instructables.com/ex/i/EF0675CE4D541029AC23001143E7E506/
Also, you'll want to put tape or heatshrink tubing, or wire insulation around the alligator teeth so that they don't bite into the wires you're working with.
