Yost Vises 904-AS All Steel Combination Vise | 4 Inch Jaw Width Pipe and Bench Vise |Secure Grip with Swivel Base | Made of Structural Cast Steel | Black

It's a beast. Still haven't figured out where I'm putting it. Maybe trailer hitch mount to the welding table.It's very smooth, large anvil. I got the yellow one so I hopefully won't run into it in the shop. Haha

It's a vise.

The only reason I gave four stars instead of five is because the pipe jaws are not for small pipe like 3/8" and barely 1/2" pipe but the vise is sturdy and didn't have much wobble and the price was right so it is a great deal.

936 - I have been using my vise for several months. It is very heavy duty and well built. I highly recommend this vise.

I'm quite pleased with this 6" vise. The jaws align perfectly and the ACME lead screw operates flawlessly. Yost lists parts including the lead screw and lead screw nut which is totally awesome. The channel is welded to the front jaw whereas all of the ductile iron vises I've seen have the channel "built in" as part of the casting.While ductile iron is generally rated at the same 60,000 PSI I believe that structural cast steel is a wee bit more "flexible" so should be a bit more forgiving before "breakage" but may very well "dent" or even bend more easily. I'll be giving this quite a workout in the next couple of weeks and will update this review if I encounter any problems.One thing worth noting - the lead screw has no stop so will unscrew entirely. The lead screw nut is fairly long but I think anything past about a 5 3/4" jaw opening would result in too few teeth engaged to achieve full clamp load. More info would be needed to calculate that but Yost says this vises "Jaws able to withstand a load of up to 1600 inch pounds (133 ft lbs) without distortion of the vise or any components".It's not designed to replace a hydraulic press but I'll undoubtedly use it to replace U-joints in truck drive shafts at some point. I should play it safe and never use a cheater pipe on the handle but at some point I know I will because that's how I roll.

Maybe just a little too much. I don't really do much these days. I probably could have gotten away with another 4" vice. Figured I'd get something a little bigger just in case. Plus the price was too good to beat. So far no issues. I have it mounted toa work bench with a 1 3/4" top. I did add a brace underneath the bottom where the bolts go through for added support. I have those fitted with fender washers and using lock washers and nuts with nylon inserts for added support. complete overkill. But it there if i need it.

To be clear I have not placed a bar or pipe in this vise and beat on it with a hammed to shape it. If you use one that way my review will not help. That said I really like this compact well designed vise. One point of the design that stands heads and shoulders above the comp, is that the base allows the vise to swivel 360 degrees. Hoodog! If you want to utilize your vise fully on a small work bench you need to be able to swing to either or both sides, so 360 degrees is important. It grips very well, sturdy so steady, finally the swivel lock is two, count 'em two, levers so one is on each side. I love that feature. I mounted this on a pre-built workbench that is 4 ft long and the size is a great match. You would not want anything larger. I did find, as are most new vises, that there was some dirty grease that needed wiping off and the main spindle threads were dry. I lubed up the threads it is smooth as silk. Do this, it will improve your overall experience. Being 66 yrs old I doubt I will be buying more in the future, but you should. Money well spent.

This vise is a real mixed bag - better than I feared but worse than I'd hoped, particularly with the Yost name attached.First off I'm not a pro, just a homeowner tired of "homeowner grade" tools that break. My first thought for a vise was to get a used one, but my area has a truly dire selection at this price point. After months of looking I decided to take a chance on something new.The good: this vise certainly seems sturdy. It's honestly overkill for me. My primary concern with this purchase was getting something that won't break. The world is rife with reports of cheap cast iron vises with casting voids or impurities that snap in half when you need them most. My hope with this vise was that the material (cast steel) and heft would prevent that. In person it does inspire confidence, although I haven't tested it's limits.The jaws on my example line up, which was a fear based on some reviews.Once clamped down, it holds fast and hard.The bad: fit and finish. So far removed from the online shots it's almost a different product. Absolutely none of the surfaces are what I would consider "machined". More like gone over once with a 40 grit grinder.There's burrs everywhere. The crinkle coat on my example had a couple of spots that got missed or rubbed off in transit.And the slop! There is slop simply everywhere slop could be. The main screw's retention pin is off by a mile, giving the handle slop. It wobbles and waggles when adjusting, because the fitment of the bar in the body is approximate at best (with no means of adjustment). The main screw binds up at 90% extension for reasons I can't quite diagnose.I took it apart and did my best to clean it up, but most of the issues are simply cast in. Honestly it's on par with stuff I've bought from Harbor Freight in terms of fit and finish.I guess you get what you pay for with this one, and not a penny more
