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
1/4 inch drive breaker bar
12-24 thread die
Hacksaw
Metal lathe
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.
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.
Cutting the Threads
After the bar is machined to the proper diameter, cut 12-24 threads and use plenty of lubricant.
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.
