I have used this crimping to for over 50 3/32″ sleeve crimps. I have not had a single failure of a crimp. It is not fool proof, you must use a little common sense when torqueing down the bolts. Make sure you keep the bolts lubricated, I use a moly grease. The only issue I have had with the tool is keeping tension on the wire rope while torqueing the bolts. It is easier if you use a bench vice to hold the lower die. I lock a pair of vice grips on the cut end of the wire rope while holding tension on the long end. This method allows me to maintain tension on the wire rope while crimping the sleeve. It takes surprisingly little effort to torque the bolts. I would say less than 25 ft/lbs of torque.
