I wonder about the function of the spring in a locking plier. I removed it from my Vise Grips and the tool still works perfectly. But I think that is a nonsense keeping a component without utility in a tool. So you guys can point the purpose of the spring, other than to keep the pliers closed when not in use??
I'm surprised the Vise Grip still works normally. I believe the spring is what holds the plier open until you squeeze the handles to lock it onto something. I know when I lose the spring, mine become really floppy-still useable, but annoying.
Thank you for sharing your experience using a Vise Grip without spring.
So, the FUNCTION of the tool could not be affected, but his USABILITY became impaired. Interesting!
I´m a Industrial Design student from Brazil and I want to develop a locking plier that may have atributes of manual and automatic ones. My aim is to develop a tool with a great grip, with a faster adjustment system.
Your comment has great value to my work. I really apreciate it! Thanks, again!
Did you ever used an automatic locking plier, like C.H. Hansom? They are good or junk?
Sorry for my english!
If someone have something more to sharing about locking pliers (the good, and, mostly, the BAD experiences), feel free to sharing here!
I have 2 automatic pliers. One is a long nose model that works pretty well. Has adjustable tension, but automatically adjusts to the size of whatever you're gripping. It's weakness is that you can't squeeze something together with it. For example, I can hold it open with my fingers and clamp it, and it won't press my fingers together. But it's fine when you get it locked on something solid. It's small, and not very powerful. I Forget the brand. I've had it for at least 20 years.
The other is a completely different design, Chinese origin, I think. It works well except when it jams, and can't be closed. May be a flaw in the design, or in manufacturing precision.
Your English is better than my Portuguese.
This is the one that jams open and doesn't want to close
This is the one I use most. It is pretty reliable, except for the limitation that I mentioned.
Since they seem to hold jigs and other parts in place. Jig is for doing a mortise in a door's stile. I have used these to clamp a metal angle iron to a concrete form, then screw the two items together. More of a portable vise.
tirmey: Thanks for the link to Free Patents Online. I didn't know such a site existed. I actually do have an invention that I may or may not try to develop into a marketable item. But I've hesitated to pursue it, because I know patents can be very expensive to get. I may just develop it with out a patent, and figure I can sell a few before the Chinese decide it's worth copying.
bandit: I use those C clamp vise grips for welding
