Picture of Mighty Multitool
This is an instructable I created for the Indestructables contest and to have a handy little multitool. I built it out of a socket wrench, an adjustable wrench, and a broken multitool I've had bouncing around in my toolbox that I couldn't bring myself to throw away, because I can rarely bring myself around to throw anything away. Anyhow, the idea is simple, and I wanted a project to try out an arc welder I recently bought. Also I will apologize in advance for the quality of my welds, I haven't welded in several years and my experience back then was limited.

Step 1: Materials and Equipment

Picture of Materials and Equipment
Materials Used:
8" Adjustable Wrench
Socket Wrench
Broken Multitool
2 4 " Mending Plates
1/16" electrotrodes

Equipment Used:
Emory Cloth
Dremel with Sanding and Grinding Wheel
Hex keys(to fasten/unfasten screws that hold the tools onto the multitool
70 Amp Arc Welder
Chipping Hammer/Wire Brush
Welding Safety Equipment
-Heavy Leather Gloves and Apron
-Welding Mask/Helmet

Step 2: Sand/Grind the Parts Clean

One of the most important steps in this project is to use a grinding/sanding attachment on a rotary tool, or an emory cloth, to clean the parts to be welded together. It is very important to have clean surfaces to conduct the electricity well with the arc welder.  

Step 3: Reassemble the Multitool w/ the Mending Plates

In this step I took the parts from the broken multitool and placed them between the two 4" mending brackets. I choose the two screwdrivers, the knife, the saw, and the can/bottle opener. Remember to include the spacer washers between the tools so they will swing freely and still have enough friction and spring pressure to hold open when the tool is in use.

What a "tool"! *Much sarcasm and pun intended* :-) Love the idea, I may make one of these to keep in the car. Good work.

You're Welcome, it was really helpful to remember a lot of the how to and safety I'd forgotten and learn some things I'd missed the first time I tried welding.
