Picture of DIY- Helping Hand Tool
Hi, I am going to you take you through a simple, cheap and easy process to build a helping hand tool.

Step 1: Materials Required

Materials required--
1) Broken computer hard drive
2) Alligator clips
3) flexible metal wire
4) Small magnifying glass

Optional materials--
1) 5mm super bright dome LEDs
2) 3.7v Li-Ion battery
3) 2-position switch (3 terminal or 6 terminal)
4) Any 2 terminal jack and sutable socket

Step 2: Prepping the hard drive

1) The reason I chose a computer hard drive is because they have a nice CNC machined chunk of aluminum with pre-drilled & tapped holes that can make a great weighted base for what we intend to do with it.
Start by stripping the broken hard drive, make sure to remove everything you can from the main aluminum console. What you'll be using is the stripped chunk of aluminum, the top cover and the screws. (Save the other parts too, most of them can prove valuable in other projects)

Step 3: Making the arms

2) Why I chose the flexible metal wire to make the arms for the helping hands is because it's easy to flex around however you need it to hold and it's pretty cheap. A bit of 2mm thick soft iron wire will do the trick.
Form a small loop at one end and screw it down to any of the desired several holes on the aluminum base. Form a similar loop on the other end and secure the alligator clip to it. Like this, you can build as many arms as you want.

Step 4: Magnifying glass attachment

3) To make a magnifying glass attachment, take a piece metal wire, form a loop and secure a small magnifying glass to it. Loop the other end and screw it down to the aluminum base; just like the arms.

Isn´t the aluminum base too light?

Considering some people use small wood bases, I think it will be ok.

Might make one myself soon, and if it is too light ill just toss in a few lead fishing weights.

Nope, its a nice weighted base, doesnt move around when youre using it.

I have a similar 3rd hand using a hard drive for my base. I was not able to add light and magnifier though :) thanks for sharing this instructible, I will add such features to my 3rd hand. By the way, I find my clips unstable, wobbly. maybe because I use a copper wire instead of a galvanized iron wire.. I'll try the kind of wire that you used, hopefully it would give my 3rd hand a more stable structure. again, thank you!!!
