A Pair of SO Pliers Breaks a Vise!

Read this in Reliable Plant, a trade publication that I browse:

I either call bullshit, a vise ready to go, or a piss poorly cast chinese vise. I have a Harbor Freight 4" Vise that has had 2"x.25" strap iron put into it and beat with a 3 lb sledge to bend it. If that piece of junk will handle that, I'll gladly flatten his diagonal cutters in it.

Sensationalism BS at it's finest.

P.S. Dad broke a 10" wilton vise with a piece of 1"x.120" strap iron. Talk about pissed.

[Junkman]

He didn't say what the vise was, so all I can assume is the vise was a toy, or the story is pure BS. Then, we don't know how he mounted the tool in the vise, so it is possible, that if he mounted it so there was only a block of steel between the jaws, put a pipe on the vise handle, something would have to give. It could have been the vise, but I doubt it. I guess if you tell a lie long enough, you will start to believe it........ just like a politician... :lol_hitti

[Uncle Buck]

I am relieved that I am not the only one to think that story is pure BS. Watch, one of the kool-aid drinkers will follow and swallow that crap hook, line, and sinker!

[dxdexter]

Sounds like Snap-on propaganda, either that or he went to bend them using a 10 lb. sledge hammer and missed, striking a crappy Chinese vise just the right way.:headscrat

Heck, the article already says it is from a Snap~on Marketing Manager, LOL.

That and my experience breaking out two welds with a vise that broke (old abused vise), says a combination of the two events.

I could state that a Toyota U-joint broke my big old Athol bench vise. The BFH and the three foot pipe may have had something to do with it though.

[old salvage]

If the story is true then that Nelson character must have been quite a tool himself to try and break the pliers right in front of the dealer.

I did the same thing with a u-joint from my 86 GMC truck years ago, cracked a very nice old machinists vise in the garage at the house I was renting. :wtf:

[eschoendorff]

Wow... I was gonna call BS, but it seems taht everyone else beat me to it. Great minds must think alike... :lol:

[hamburglar]

I'll bet that Craftsman pliers would do just as good a job of vise breaking.

"Nelson clamped the pliers into his bench vise and yanked on the handle. I heard a loud snap"

What a crock.

I can believe it happened, but only if the vise was already cracked. A 6" handle, fulcrum being the top of the jaw, and point of pressure the bottom of the vise jaw maybe 1" away, force is multiplied by say a factor of 6. Normal clamping force is with a 8" handle, wild guess the pitch of the bolt thing is about 8, more wild guess is that 1000 lbs of clamping force is common. Mongo might put 200 lbs on the pliers handle for the same 1000 lbs of force.

I've seen some extra ordinary tool failures, but that is a little extreme.

Maybe, who knows. Stranger things have happened.

I broke a nice old Craftsman vise with a pair of Radio-shack long-nose/ crimping Pliers.

I Had a bunch of connections to crimp when i was re-wiring a bakery oven. To get a good connection, i'd start the crimp by hand and then I'd put the pliers in the vice and snug it down.


On about the 10th one, the vise screw broke. I dont think craftsman's warranty applies to vices, especially ones that are 40 or 50 years old.

:headscrat Damn... must've been the amount of fatigue over the years finally caught up with it.

bet if you found the right vintage catalog you would find that it was a lifer at the time if it is that old. :pimpflash

[bigjon]

I heard a similar story but it was C'man pliers and a SO vise :lol_hitti

I found it in the 1964 catalogue at roseantiquetools.com

Says "lifetime warranty on the castings." I broke the screw.

I think that i'll approach the local high school shop teacher and see if they would consider turning me a new one. It's basically an acme screw thread with a few simple turnings on the end and should be a good lathe project for a student.

I agree, great learner lathe project. If he says no, check out McMaster Carr, they sell acme threaded shafts in different threads and various lengths. Good Luck. :beer:
