Yost Vises M7WW Rapid Action Woodworking Vise | Quick Release Lever for Quick Adjustments | 7 Inch Jaw Width | Made with Heavy-Duty Cast Iron | Blue

I recently received and installed the Yost 7 inch model M7WW. Very pleased with it. It seems almost stupid heavy, but good vises are. It is a nicely finished, well made, quality product and the rapid action feature makes it a pleasure to use. It has great clamping force - no more vise jaw racking and work pieces slipping. Limited use so far, but It held everything solidly while I sawed and planed material. The vise is easily operated with one hand, even the rapid action feature, leaving the other hand free to position the material to be clamped. Be aware - this thing is heavy, the shipping preservative makes it slick, and it comes with very sharp edges. While lugging the boxed vise downstairs to my shop, I pretty much knew I would need to reinforce my light weight workbench to handle this blue monster. Working over a layer of cardboard on my work bench, I removed the preservative first, using a citrus based solvent and paper towels. Be careful around the sharp edges of the vise jaws. Cleaning the vise threads was easier after the vise was mounted: I put several layers of paper towels over the edge of a putty knife and held the blade into the thread recesses while turning the vise handle. After cleaning away the preservative, I spent several minutes with a file removing the flesh eating sharp edges along the machined surfaces, vacuumed up the metal filings and a little flesh, then washed my very dirty hands. I applied Boeshield T-9, a lubricant and metal protector that leaves a dry surface to minimize sawdust build up. I then quickly mounted the vise to my bench and lived happily ever after! In my dreams, anyway. My installation become a bit complicated. If interested in ghastly details, continue reading. I set my workbench upside down on a table so I could better access the vise mounting area. Two problems became immediately apparent. Alas, there would be more but less apparent problems later on. First, my work bench’s seemingly 2-1/2 inch thick top was not solid. It has a 3/4 inch thick top set inside 3/4 by 2-1/2 inch wide skirt boards. This leaves a void of 1-3/4 deep by about 4 by 18 inches in the area where the vise would be mounted. Yost recommends the bench top be at least 2-3/8 inches thick where the vise is to be mounted. The second, immediately apparent issue involved the bench’s wooden crosspiece that supported the top and the legs. This crosspiece interfered with the vise’s sliding mechanism that hangs about 3-3/4 inches below the bottom of the bench top, is about 5 inches wide, and projects back under the bench about 12-1/2 inches from the edge of the bench top. If I would have mounted the vise on the side of the bench top instead of the end, I might have avoided this leg crosspiece interference problem, but that wasn’t the location I wanted. For the void issue, I decided to fill that area in with 2x material ripped and cut for a snug fit flush with the bench top skirting, then glued, screwed and clamped all of the pieces into place. I sanded the varnished bench top under surfaces prior to gluing for a better glue bite. I added a 2-1/2 inch wide piece of 2x4 to the end of the bench top to provide a solid place for anchoring the front two vise mounting lag screws, rather than in a glue joint. Then I covered the bottom of this ripped 2x4 and the filled in area with a layer of 3/4 inch plywood, glued and screwed into place. While the plywood layer would put the top of the vise 3/4 inch below the bench top, it reduced the crosspiece interference problem to an acceptable amount of crosspiece material to be removed. It also added reinforcement to the area. The vise would now mount against the plywood and the 2x4. Apparently I was becoming a vise snob as I felt the need to stain and varnish the added wood before attaching the vise. Finally ready to mount the vise, I clamped the vise into position, drilled 1/4 inch pilot holes for the four 5/16 inch diameter lag bolts (not included), and fastened the vise to the bench. This area of my bench top was now 3-1/4 inch thick, and with the added thickness of the vise bottom and a flat washer, I used 3 inch long lag screws. I carefully set the now much heavier work bench back on its feet. With the vise anchored to the bench, the vise’s smooth and rapid action was amazing. The added plywood layer also meant that the vise dog would no longer extend above the top of the bench. I couldn’t find longer dogs or dog extensions, but did find an online site offering a steel bar measuring 1/2 x 1 x 4 inches. After a bit of grinding and filing the 1/2 inch thickness back to about .47 inches on the lower 2-1/2 inches of the steel bar, it now fits into the dog pocket of the vise. I now have a drop-in steel vise dog that extends an inch above my bench top when needed. With the new vise fully extended, the handle is about 18 horizontal inches away from the nearest leg pair. That’s a lot of overhang on a fairly light work bench. With the vise closed, the overhang is about 11 inches. I cut pieces of 2x4 to make two bench leg “side extensions” that were 20 inches long, tapered them for a better look, and also stained and varnished them (that vise snob thing). These were screwed to the bottom part of the two bench legs closest to the vise, with the 1-1/2 inch edges extending toward the vise, touching the floor, and reducing the overhang by 3-1/2 inches. This seemed effective and also noticeably stiffened that pair of legs. See the attached photo, which also shows modifications for a different project. There was still some undesirable rocking of the workbench’s legs, so I made a 14 inch long diagonal brace for each leg using 1x4’s mitered at 45 degree at both ends, and screwed them to the bench top skirt boards and to the legs. This made a big improvement in the bench’s stability. Vise jaw faces. The jaw face mounting holes in the vise jaws are not threaded, and the front jaw face mounting holes are not aligned with the rear jaw holes. Wood screws or sheet metal screws will be needed to mount the jaw faces. While the rear jaw face could be attached with screws from the back of the rear jaw, it won’t then be possible to remove the face without removing the vise. I wanted to be able to quickly and easily swap out jaw faces, which meant attaching the rear jaw face after the vise was mounted, with visible but recessed screws, through the rear jaw holes and into the edge of the bench top. It is easier to mark the position of the rear jaw face screw holes on the back of the face before the vise is mounted, by working from the back of the rear jaw. The front jaw face is easily marked and positioned after the vise is mounted. I used 3/4 inch plywood for my first set of jaw faces, and cut them 3-5/8 inches high and 9 inches wide, a bit taller and wider than the 7 inch wide jaws. This put the the top of the jaw facings at the same height as the bench top after my modifications. I knew it would be a bit of a challenge to put this vise on my particular bench, but I’m glad I made the needed modifications as this vise is so way better than my previous vises. It is truly a bargain - buy it!

Bad things first... Installation (for me) was kind of difficult/tricky. The most difficult aspect is the weight of the vise. If you are able to turn the installations surface upside-down, then it will be much easier. I didn't have that option, so holding it up to determine location/depth/etc... was a challenge. Definitely try and have a second set of hands (preferably attached to someone who is patient). The good... Excellent quality. Extremely sturdy. The quick-release is something I've never had on a vise, and it is an amazing feature and a time/frustration saver. Very smooth movement with the quick-release and the crank/screw. Holding power is great. I opted to mount mine as an end-vise, and covered the mounted face with a board that recessed around the face to hide the metal (and provide a softer clamping surface), and extended the full width of my bench in order to make it appear as though it is not even there. On the moving face, I also mounted a full width recessed board on it, which covers the face and a lot of the edges (again, providing a softer clamping surface). The only downside of doing that, was that it covers the built-in dog. However, the wood I used as a face was 3 inches thick, which allowed me to put 3 dog holes in the top of it, to match up with dog holes on my bench, providing a "secondary" clamping option for long boards to lay flat on the bench. Anyone looking for a solid vise, that also provides the ability to make a pretty good looking end vise, should consider this one. It really is something I wish I had years ago.

Well build vise. I took a star off fir a couple of reasons: - the handle is plain steel, not protected against corrosion. It is lightly piled, which keeps corrosion at bay while in the box and shipping, but is unacceptable for a woodworker. I will probably spray it on a regular basis with some dry silicone or such. - The jaws have what is called toe-in, which means that they are not parallel, when the top of the jaws touch, you still have 1/8" gap. The pressure of the screw is applied on the bottom of the jaw, so the tow in is supposed to compensate for that and once the jaws are tighten up the gap should close. The caveat here is that if you clamp soft wood, the steel jaws will not bend but rather indent the top of your piece. Some would workers like toe-in, some don't. This is an important and differentiating feature and the manufacturer should mention it in the description- They do not. I contacted the manufacturer about this and they responded in less then 24hours, which is why I only took 1 star off and not 2.

I bought the 7" model on sale back in December to use as an end vise on my woodworking bench. My bench has a 3" thick laminated top which meant I had to remove about a 1/2" of material in order to have a flush mount with the top. That was a surprise to me based on all the videos and pictures I saw for the Eclipse brand vises that look almost identical, and some of the larger Yost vises. I was expecting to have to add a shim, not remove material, but since my bench doesn't have a maple top I didn't mind chiseling out the material. I just want to mention this for anyone else thinking it's taller. I believe it measures around 2.5", whereas some larger models are 3.5". Mounting the vise: I can only speak for the 7" when I say it's not difficult, but I can't imagine the same method not working fine for the larger models too. Yost included instructions in the box which must be written for the larger models because it called out using a shim if your bench top is less than 3" thick. As I explained above that was not the case on mine. Aside from that the instructions had what I consider the best method. Use #10 or 1/4" screws at least 2" in length for the rear vise jaw and screw it to the bench. I added a 3/4" poplar jaw face and recessed the screws about 3/8". After I screwed the vise to the end of my bench I was able to mark and drill my holes on the bottom for the lag screws. I can't say if the two screws through the jaw will hold the larger models but they held mine no problem. For the bottom I used two 3/8" lag screws 2" long for the front holes and two 5/16" lag screws 2-1/4" long for the rear slotted holes. I would have used all 5/16" but didn't have anymore on hand. If I had the 9" or 10" version I would have used 3/8" most likely. I realize some people feel it's necessary to install bolts through the top as opposed to lag screws through the bottom. My suggestion is to go with whatever you feel is safe, but Yost recommended lag screws through the bottom and I feel they are holding fine. Once I had it mounted I added another poplar jaw face for the rear jaw and used my hand plane to flush up both jaws to the bench top. I have been using the vise every day and absolutely love it. The action is very smooth and the rapid feature is a must now that I've finally tried one. I don't know why I waited so long to get one of these but at least I have one now. I feel like this vise will last a lifetime if I take proper care of it. Yost recommends a dry grease for the vise screw and I just have to keep the sawdust out of it as well. I may make some type of shroud to install around the vise screw to keep it clean, like some of the more expensive vises offer. In closing, I highly recommend the Yost 7" rapid acting woodworking vise.

I bought this vise for my small basement woodworking shop. This is Yost's smallest woodworking vise, but it weighs in at 22 lbs. nonetheless. It seems well-made, feels rock solid, and should last 100 years. The jaws line up perfectly. I like the quick-release feature and the chunky built-in retractable iron dog on the movable jaw. Cons. The screw is just a bit stiff to turn and the quick-release is also a little stiff, but both are very functional. The vise had been dropped hard on the back end of the screw during shipping. That was evident because there were holes in the factory box and the Amazon outer box that had been created when the vise landed. The end plate was badly bent and one side of the screw shaft had flared upon impact. I had to file it off to remove and straighten the end plate. Fortunately, my DIY repair was successful, so I didn't have to initiate an exchange. I'm sure the interesting screw profile is not new, but I was impressed with its dual functionality. The profile allows very high pressure to be applied during clamping, but when backing the screw out, the profile also permits the nut to cam out and ratchet when it encounters resistance such as when you reach the end of travel. Thus, you can't damage the mechanism by backing out "too far." I think I'm going to love this vise. I would recommend it for amateur woodworkers or a pro shop.

I used this on my woodworking bench. I added a couple pieces of oak for the vise faces, and it's terrific. I especially like the quick release for opening/closing the jaws to the right distance before clamping down

The finish is adequately smooth and the fit and accuracy of the moving parts is very good. The vise was easy to install on my homemade workbench. The cast parts seemed to have good ductile strength, not brittle like poor quality cast parts can be. I know there are woodworking vises with greater precision and perhaps more versatility, but for my home shop this is a very useful addition at an attractive price point. I installed soft wood jaws using the provided mounting holes and the vise is non-marring to my workpieces.

I have a small bench in a tiny space to do wood carving and small woodworking projects. I've used the traditional face vises on other benches and wanted more flexibility, so I upgraded to this Yost 7" quick release vise. I'm extremely happy with the vise and most impressed with it! First, the quick release might seem like a gimmick, but boy can it save you time as you move pieces in and out of the vise! Instead of cranking around, and around, and around, you flip the lever and slide the vise open or closed in a second. Those saved seconds can really add up in the middle of a project! My short movie shows the quick release in action. The Yost vise is easy enough to mount, with four bolts holding it to the bottom of the bench. I mounted mine by flipping the bench top upside-down, but you can make a 90 degree bracket that holds the vise to the bench as you drill in from below. Either way, four lag bolts are more than enough to hold the vise securely. The vise is solid, with a good weight. In addition to holding items between the jaws, I can hold items flat to the top with the built-in bench dog and long boards across the face of the bench (with extra supports). The jaws are set up so you can easily secure chops to the vise jaws to protect your wood projects and if the wood is strong enough, it can expand the width a bit, as I did with the beech chops. This adds to the flexibility by allowing to clamp wider items below the guides and screw. I highly recommend this vise for woodworking! It's become an indispensable asset on my bench!

was able to install without a hitch. The spindle machining is very rough and could have benefited from a sharper cutter to prevent galling. But still it is currently , as delivered relative tight and it will probably take years to develop any slop. This vise is virtually identical to a comparable Eclipse vise at half the price. The only beef I have is that there is a little radial play in the front face so it does not stay parallel with the fixed face, I have several woodworking vises in my shop from high end to utility , this one works as well . one thing I recommend is, use good quality double-sided tape for attaching hardwood yaw/ work piece protectors. This also allows you to plane the top of the now hardwood yaws flush with the top of your workbench and compensate somewhat for the radial play in the moving yaw

Great, thank you!

Excellent copy of a Record vice.....and priced VERY nicely at this time. Castings were a tiny bit rough but nothing that was going to interfere with it's smooth and easy operation. In my case I had to drill out the 2 front cast bolt holes slightly larger to accommodate my choice of 5 inch carriage bolts although 4 inch would have done in a pinch. Someone had mentioned a stiff quick-release arm but mine was silky smooth. Another reviewer mentioned a discrepancy in the mounting points but these are BELOW the mounting surface and do not in any way interfere with the vice's ease of mounting or it's final resting place. A quick greasing of the main gear was all I had to do after I flush-mounted it to my bench. As it mounts beneath an existing bench the thickness of the bench-top needs to be approximately 2 3/8 inch and the cut-back notch for the stationary side of the vice about 1/2 inch or so. Easy to install and rock solid when it's completed.

Good, solid vice and worth the money I paid for it. It closes smoothly, but the quick release mechanism seems a little stiff. It would be nice if it came with installation instructions, but there are enough websites and youtube videos showing how to do install a vice like this and it was easy enough to install. I've already drilled some holes in my workbench top to take advantage of the pop-up bench dog. Right now i'm using dowels in the holes, but I'm thinking of getting some actual bench dogs from Kreg to see if they could work.
