Building a modular 3rd hand
Channel: Bad Decision Works

Using some 12mm round stock and an old drill press chuck.

3rd hands are very useful tools used for welding. This metal "finger" keeps your small bolts, nuts, tabs and other stuff in place with its weight so you can use both of your hands to tack and weld the pieces together.

The big advantage of this modular setup is that you can use different kinds of "fingers". If the tool doesn't fit the job, bend a new piece of steel and make it fit.
