JawHorse Sheetmaster Portable Work Support Station is rated 4.8 out of 5 by 120.
Rated 5 out of 5 by from Built like a tank! I haven't actually started using this for projects yet but just experimenting with it and getting used to its features I am very impressed by the construction of this tool. Very heavy duty. It will serve its purpose for me.

Rated 5 out of 5 by from Wonderful - countless uses for a paid handyman I chose the sheetmaster for the larger jaw size - currently designing my own custom accessory tables for some of my portable tools - may buy another at a later time for bigger projects

Rated 5 out of 5 by from Great product! What a life saver! I don't have to worry about "the other end" anymore! Holds 4'x8' pieces down to the smallest item you might need to work on.

Rated 5 out of 5 by from Rock Solid My three reasons for initially considering this purchase: 1. Three-legged support, which is easier to stabilize on my uneven driveway (vs. a traditional 4-legged sawhorse). 2. Full-sized plywood sheet clamp (which secures a 4' wide sheet). 3. It folds to a small footprint when upright, which is perfect for my limited garage space. It's heavy, but the benefit is a rock solid base of support. I'm glad that it has wheels to roll around. It pairs perfectly with my Rockwell JawStand XP (also three legged), which can be height-adjusted and angle-adjusted to match the JawHorse on uneven ground. This is a nice portable alternative to a workbench if you're short on space and/or have an uneven work surface.

Rated 5 out of 5 by from JawHorse SheetMaster The SheetMaster is very stable and very able. The clamp pressure is very easy to control from light-touch to crushing pressure. I immediately built a 2-part worktable (sliding side: 2'x2', stationary side(2'x6")) with holes for bench dogs. It is similar to a table that apparently is no longer sold. With this addition, the SheetMaster truly becomes a key work area in my shop.... Fantastic tool!

Rated 5 out of 5 by from Makes large jobs more manageable Was given an accessory as a gift, but not the JawHorse, so I bought it so the accessory would not be a waste. Turned out to be a great decision, very helpful and makes jobs less awkward.

Rated 5 out of 5 by from Great Jawhorse.... Jawhorse is a great tool, help me during my everyday work venture. Easy to assemble and hold and clamp a full 4x8 sheet of material. Just what I needed.

Rated 5 out of 5 by from Like an extra hand that you don't have to pay. Bought mine about 8-10 ago been so long I forgot, am glad I did. I am a one man operation having the Jaw Horse is like having a person that can hold a hundred pound straight out all day long. Jaw Horse doesn't need a lunch break .

Rated 5 out of 5 by from Perfect helping hand! Bought this to help in a deck build I am starting, just getting going on the project, so not much use yet but it's very stable and will be a big help, especially with holding and cutting long heave lumber.

Rated 5 out of 5 by from A tool that provides a second set of hands. Used this for times so far in a month working on small projects.very convenient. Great engineering. Should have purchased years ago

Rated 5 out of 5 by from Outstanding tool The Jawhorse Sheetmaster is the real deal!! No job too big for it to handle! It has made my projects move along much faster . It is a solid platform that can handle large/ heavy loads. Well done Rockwell!!!!

Rated 5 out of 5 by from Just Awesome I purchased the Jawhorse Sheetmaster on the off chance that the extra reach might come in handy on some projects. Turns out my first required breaking down a full plywood sheet. I've since made a 3/4" table top with a 4x4 runner that clamps securely into the vise, giving me another use for the Jawhorse. The fact that the whole thing can be disassembled, and the Jawhorse collapsed, means both occupy a tiny footprint in my workshop/two-car garage; which also stores our vehicles. For a person just starting out in his first home, this is really going to come in handy on most of my future projects.

Rated 5 out of 5 by from Great Addition to My Toolbox I can't believe how much easier the Jawhorse makes so many woodworking projects. It sets up fast and it's very stable. Should have purchased it long ago. Well worth the price!

Rated 5 out of 5 by from Great! Even more useful than expected but not as intuitive to fold as expected.
Date published: 2017-05-22
Rated 5 out of 5 by from Makes projects unbelievably easy Have had my Jawhorse for several years now and am constantly amazed each time I use it. It's like a second person helping you. It also increases your safety as it allows you to use both hands to hold your planer, belt sander,ect giving you safer control of the tool. If you don't have one, you're working way too hard to complete your projects. Once you use the Jawhorse, you'll see what I mean.

Rated 5 out of 5 by from Perfect, everything I needed and more. I bought this to better clamp 2x4s - building some free-standing shelving out of studs/plywood in my basement and figured this would make it easier to manage cutting and pre-drilling both. Turns out it also makes a phenomenal miter saw stand as well. The clamping force is strong enough that the sliding miter saw doesn't budge once it's put in. Folds down way more compact than a miter saw stand, too.

Rated 5 out of 5 by from Excellent helper I received this tool and it has lended a hand that nothing else could have. I would not trade it any other tool like it

Rated 5 out of 5 by from Best invention for Large Lumber I bought this in January 2017 and I must say I absolutely love it. Works exactly as described. Held 10 foot 3/4" hardwood boards, sturdy, secure and accurately. This is better than any table, clamping mechanism or pair of saw horses, ever! while this tool is a 'unitasker' it's already replaced my saw horses and other support tables and it stores much smaller than all of those other items combined. At first, it was difficult to 'release' the sliding, green clamp, as the instructions were not as helpful to find out how (but what manuals are?). Well worth the money. My only regret is that I should have bought two!!!
Date published: 2017-02-22
Rated 5 out of 5 by from Rock Solid I love this thing. Absolutely one of the best purchases I have made as far as my wood shop goes. It is very sturdy. I use it for sawing, sanding, plaining, etc. It holds what I put in it and doesn't let go until I release it. Fantastic. Home run Rockwell!!!

Rated 5 out of 5 by from Well built. I bought this product so I could more easily cut plywood as well as other lumber. I first noticed that it is well packaged and arrived in perfect shape. I removed from the box, read directions and set it up. The first thing that you notice is that this product is not light, it is made of very sturdy steel. I appreciate a well built product, there is nothing worse than buying a flimsy piece of junk. Overall the Sheetmaster looks good and has wheels to move it around when it is folded up. The clamp is strong and will not let go of whatever you put in there. Clamping is easy because you hold your work piece with your hands and clamp it down using the foot pedal. I used it and had no issues, overall it seems to be a very solid product that will last for years.

I really wish I would have known about this long ago. Every where I go, if I'm talking to someone that has any kind of a work shop, I make sure to let them know about my new awesome extra muscle at home in my wood shop. Thank you Rockwell tools for this quality piece of equipment. I'll make sure if I can help it, every friend and family member of mine will have one of these to make their life a whole lot easier!
