Vise Grip Super Mod

Introduction: Vise Grip Super Mod

So what can be modified on an ordinary vise-grip? Just about anything. Here is a fairly easy modification but does require a metal lathe. This project will combine a 4 inch vise-grip and a 1/4 inch drive breaker bar. Essentially the knurled adjusting nut is being replaced with the breaker bar rod. This combination is compact, versatile and strong (for its size). Perfect in a must have tool kit. No functionality is lost for either tool.

Supplies

4 inch vise-grip
1/4 inch drive breaker bar
12-24 thread die
Hacksaw
Metal lathe

Step 1: Prepare the Breaker Bar

Cut off the very end of the breaker bar just past the ball stop. Very often there will be a tiny spring loaded ball bearing in the breaker housing. Try not to let the ball get away as you will have to use it during reassembly.

Step 2: Machining the Breaker Bar

The cut off end has to be machined down so 12-24 threads can be cut. Depending on the brand of the vise-grip, the threads and length can vary. This step just replicates the knurled bolt.

Step 3: Cutting the Threads

After the bar is machined to the proper diameter, cut 12-24 threads and use plenty of lubricant.

Step 4: A Finished Vise-grip Super Mod

Hey, you're done! This modification can be scaled up to any size vise-grip. This project took about 20 minutes. If you don't have a metal lathe, ask around or visit your local maker space. I highly recommend this multi tool.

    Good idea, but rather than the breaker bar, I think I'd get more use out of a rachet head afixed to the vise-grips. Same principle, just more handy for me. Hadn't thought about a combo before. WIll have to try it out now. :-)

    Hi Big_Jethro, as I mentioned, the possibilities are endless when combining tools. I think a wrachet head would be very useful. Please post a photo when you are done.

    Sorry, I will clarify. The part with the square drive has a tiny ball bearing inside to keep it tight to the long rod. It was never meant to be disassembled. Once the drive slides off the rod, the bearing will then fall out. Replace the bearing before the drive slides back on. It will still operate without the bearing, but will be slightly loose.

    Would like a visual example of it in use to actually see its usefulness "

    Well, a vise-grip can grab and hold just about anything that can fit in its jaws. But now you have a 1/4 inch breaker bar that goes everywhere the vise-grip goes. Snap on a 1/4 inch socket and now you can loosen or tighten small nuts and bolts. Sorry if I wasn't clear enough.
