Third hand stand. Danger to parts?
Posted by somenewguy on Tuesday, January 29, 2008 5:59 AM
Just got a third hand standBig Smile [:D]. Got home and began toying around with itConfused [%-)]. Put my pinky finger in one of the  clamps to see how much tension they had believing that they would  be fairly weak. Boy, was I wrongSign - Oops [#oops]. They ain't weakTaped Shut [XX]. And that lead me to believe that most or some parts (or any part mounted in the clamp/s in the wrong position) will simply break under the pressure. Are they safe for all parts, or should I be very careful with what parts I lodge in the clamps as well as the position I mount them in? Cheers.

I have some of the note holders that are given away by companies as promotional items. They work great for holding small parts for painting. You can relax the tension of these alligator type clamps by heating them. Don't get them too hot or they'll loose all of their grip.

You can also clamp the clamp. That is use a clamping device that is gentle to the part to hold it, then hold the clamp with another holder with a firmer grip.

I got the Third hand stand.  To minimize damage when using the clamps, I wrap each jaw with masking tape a few times thick.  This provides a cushion when a part is clamped.

You can also take a small length of surgical tubing and slip it over each jaw of the alligator clip.

It cushions the part and also helps with gripping the part.

Cool idea, Mike.  I'm going to give that one a try.

Thanks Jesse. I should have been a mechanical engineer like my oldest brother. Big Smile [:D]

I just tore off a square of cardboard from a model kit box, folded it a couple of times, and use that between the part and the jaws on my third hand. Seems to work well so far.
