It wasn’t the hinge. These tools aren’t designed to cut with a torsional load. Next time let the tool work and readjust.

I would say it's the opposite of let the tool do the work. Good catch phrase, but in this case you have to fight the rotation, or readjust. Tip loading, or a twist that allows the metal to get between and spread the blades apart is what causes this to happen. I think of the tool doing the work as stepping back and letting things break when they do. It could read "let the tool do the work until it starts to spin" and readjust.

So you can only let cutters move on the same plane as the blades?

Yes, that's a good way to explain it when it comes to these Hurst edraulics. I don't have experience outside of Hurst. If they move off plane a little, they will be fine. I fight the roll, and if it looks like it's going to beat me, I readjust.

Thanks, I too have very limited expirience outside of hurst, and for some odd reason, the VFD that I am with ( which from 2017-2023 ran avg of 30-50 entrapment calls) has run ONE pin job since I started, and I wasnt even there. Needless to say, my knowledge is still limited to a few training cars.
