Rockwell RK9002 JawHorse Sheetmaster Portable Workstation

Servus zusammen,ich weiß überhaupt nicht warum dieses Gerät oder besser die Art, hier in Mitteleuropa fast gänzlich unbekannt ist.Ich bin durch einen Megazufall darauf gestoßen.In einem Beitrag von April Wilkerson dachte ich mir, WTF, was ist das da?In der Liste Ihrer Werkzeuge stand dann JawHorse. Was zum Teufel ist ein JawHorse!?!Ich kann sagen, ein einfaches und wirklich geniales Teil.Ich habe darauf geachtet dass ich Werkstücke von mehr als 1200mm einspannen konnte, ja und Zack, da habe ich mir das Dingens hier bestellt.Egal was, drauflegen, einspannen (der Druck ist hervorragend einstellbar- ich spanne u.a. 10mm Gipsfaserplatten ein) und loslegen.Der Stand des Bocks inkl. des Materials ist einfach Mega!Fazit:Jeder der Plattenwerkstoffe oder Türen bzw. Fenster aufarbeitet bzw. bearbeitet sollte sich sowas hier anschaffen!Wenn möglich noch mehr Sterne!Vielen Dank an April!Beste Grüße

Arrived very promptly impressed with the delivery service.As mentioned in other reviews it is a little on the heavy side, but this is due to the outstanding construction. It truly is built to last.Typical man I didnt bother with the instructions to put it up and took a while to figure it out. It requires turning on its back and getting the legs and clamp system opened in the correct order. If you have a back injury or mobility issues this is not something you will want to be putting up and down on a regular basis. But the footprint isnt too large so could be left up for the home DIY ehthusiast with enough space.Folding it up requires it to be flipped over again and I have noticed that when you do start to turn it over, and put pressure on any of the legs to act as the pivot, they are prone to start to fold up. It is essential that all safety clips are checked to be firmly seated before you start to roll it over.Due to its weight and shape it will soon trap your hand or collapse in a heap if you dont follow the instructions carefully.But it does exactly what it says on the box. 10/10 for design and construction very impressed indeed.

I have never owned a jawhorse before, and decided to get this newer model, the sheetmaster, instead of the original. It was a little more money, but the added features and ability to handle 48" wide sheets without buying additional adapters was a bonus. It is my understanding that this version is a little beefed up from the original, has the 48" capacity out of the box, has a different wheel/rolling system, and is easier to break down.I wanted a jawhorse to basically use as a portable vise. To hold material securely when cutting off 2x material, to hold larger items while sanding, chiseling, or ripping, etc. I was sick of working on the ground, or inconveniently on saw horses, etc. Since I got it, I've also used it as a miter saw stand, which worked great.I watched and read a lot of reviews, and determined that even though this unit is expensive, it would be worth it to me, and it definitely is.It is super easy to set up and break down. It takes maybe 30 seconds to unfold a few legs and flip it over, and vice versa.The clamping force is great. I haven't tried to measure it, but it is definitely more than enough to secure whatever you put into it. The jawhorse is not really prone to tipping due to it's design, but obviously can if you force it, and I say this to say that from my off the cuff tests, I get the unit to tip before I can dislodge/slip the material that is locked in the jaws. This is to say, the clamping force is fantastic. And super easy to clamp something by allowing you to use your foot, which frees up both hands to make sure the piece is placed just the way you want it.I have yet to put a full sheet of anything into the jaws. It comes with an extra jig piece that quickly clamps and holds holds two pieces of 2x material at 90 degrees that is meant to be additional support for full sheets. The two pieces at 90 degrees form an "L" where the mid point of the long side of the "L" rests on the jawhorse to support the long dimension of the sheet, and the short side of the "L" rests on the ground. It looks to be pretty quick to set up, but you'd have to have that 2x material handy whenever you plan to do full sheets (maybe not as travel friendly then), and would have to set up the clamps each time. And then you wouldn't want to lose the clamp jig, and it does not store with the unit itself. This is all to say that yes it does full sheets, and I'm sure it is great at it, but it's not a fully integrated solution that all packs away into the unit itself. If you're going to be cutting a number of sheets, it's definitely worth it to set up the extra jig and go to town, but otherwise, you'll probably not be using it for single sheet cuts. This doesn't mean that the 48" jaw capacity is not useful though, beacause there are still times where you may want to hold something "long ways" by its <48" dimension, and as long as it's not wider than a few feet, you wouldn't need the support braces.One gripe I have about the unit, the only one so far (unless you count how cumbersome I view the support brace setup to be), is that when you try to wheel it, (a neat feature by the way, that you can compact it, and it wheels with the leg as a handle), a combination of the wheels being small and close together results in a lot of rocking while wheeling. You wind up fighting it while wheeling it, even on flat ground to an extent. Like a crappy suitcase where it's constantly on one wheel, then the other, then the other, back and forth, etc. You have to baby it to get it to roll properly, even on flat ground. If you are trying to do stairs, or go over grass or anything else, forget it. I personally have about given up on the wheels and just carry it. If you're going 10 or 20 feet across the garage, the wheels are OK, but more than that, it saves time and frustration to just carry it. My understanding is that the two wheel design this unit has is different than the single roller the original jawhorse has, and is supposed to be better. I haven't used the original, so I don't know how that one works, but I can say that I am not too impressed by the wheeling capability of this unit. It's fine for flat ground, and I guess not *too* bad overall. Let me say this... it's better than not having them, so there's that. But I do think they could be improved.One other note is that you need to be careful with the clamping force. It's hard to control just how much you use, and when removing it, just like an E-brake on a car, you need to apply *just* a little more force than you used to clamp/lock it, which means a little more clamping force needs to be applied to remove a clamped item. You wouldn't want to use it to hold anything delicate. For example, I tried a test piece of 1/2" copper pipe, and found that it was difficult to secure the pipe without crushing it out of round. Even when I got it to hold without hurting it too much, it was far too easy to press too hard on the foot pedal when releasing it and just smash the copper flat. You don't realize how much clamping force it really has until you see this and how easy it is to do. It's one thing to clamp things in a normal bench vise where it closes slowly, turn by turn by hand, but with the jawhorse where you use your foot and a lot of clamping force is applied very quickly for what feels like not pressing very hard with your foot, it can be a problem for these delicate items. This is awesome when grabbing wood and items that aren't easily crushed, but it does mean that you want to be careful with anything that you would be weary about in a normal vise.I would remove a star because of the wheels, but it's not a key enough feature to me to do that. It really is a 5 star item IMO. Extremely well made, performs its functions extremely well, and is just a down right awesome tool. I love it.

I bought one of these in 2012 and it's used almost daily ever since. The main reason I chose this particular unit was because it is capable of clamping a 4'x8' sheet of plywood. It really will clamp a sheet of plywood securely! From a safety standpoint, it has really helped me. No one wants a sheet of wood to move on them while they are cutting, but I've had that happen numerous times. I don't have a lot of room and just haven't always been able to clamp my workpiece as well as I'd like to. This jawhorse fixes all of those issues.I made a plasma-cutting rail system that clamps into the jawhorse. It's heavy at 70 pounds, that's why I clamp it to the jawhorse. But it gives me a platform for making smooth plate cuts. I put my plasma cutter into a carriage and it glides over the metal plate below that is to be cut. Very nice straight lines, it's better than I could do by hand.I also purchased the welding attachment for this. This was money well spent, but I'll go into that in another review. The two are awesome together and give you an extra set of hands to hold things.The clamp system is unique and very strong. I like that you use a foot pedal to lock in the clamp, it frees your hands to line a part up while you apply the foot pedal to lock it in. You have to be careful with the clamping pressure, it will literally break things if you clamp too hard. And to release the clamp, it's just a flip of a switch and then you push down slightly on the foot pedal.I made a base for my Miter Saw so that the saw sits securely in the Jawhorse. Later, I plan to add extensions to the base so that the extensions can support workpieces that are longer. The Jawhorse is so handy, I find new uses for it every day. It's a tool that you will pass down to your kids because it's well built and built to last.Everything about the jawhorse is well thought out and it's made of heavy enough steel that you know it's going to last a long time. It's not a cheap sawhorse, but it does so much more than just support your work. The last feature that's pretty great is that it easily folds up to where it only takes up about a square foot of garage real estate. That's important when you don't have a lot of room, but as small as my workspace is, I rarely ever take my jawhorse down. It's a fantastic tool and I don't think anyone would regret ever getting one.

The Rockwell RK9002 48-Inch JawHorse Sheetmaster is the ideal partner for the solo handyman. It extends to hold a 4x8 ft. plywood sheet, and comes with a clamp to extend the support surface using 2 by 4's. It is robust and is not made out of cheap stamped metal. The 3-legged system prevents tipping. In addition it can be easily folded up and comes equipped with built-in wheels. It is worth the investment. There are accessories available for clamping chainsaws, mitre saws and rollers. You won't be disappointed with this as your work project partner!
