Good day
I have those cheap grip clamps and after some use I noticed (as expected) 2 problems.
The plastic "handle hinge housing" breaking and
The jaw was sliding back and not "gripping"
For the first problem, I replaced the hinge with bolt and nut.
For the second problem, I grind the bar with #40.
The repair was so good that I made it on all the clamps, even the good ones.
Actually, I recommend to make it on the "good" ones because there is more "meat" for the bolt to hold.
Another improvement is...yep, the sanding paper, it grips like a Crocodile...
