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.

I had trouble deciding if this was a 5 or a 4 star product.

Pro's: Very sturdy, holds a full sheet of plywood, fairly portable
Con's: Clumsy to roll and carry, tripping hazard, comes with silly looking wood holder, very hard to remove yellow part, see below for rest.

Overall I like the tool, it's my new favorite thing. Long gone are the days of having to clamp a piece of wood to my bench to cut with a recip or scroll saw. To cut odd shaped things I would have to drag my tools outside. Now inside I can set it up, open, clamp and work. Clamp a piece of wood in the jaws and place a small table saw, or make it into a bench. The jaws have removable rubber covers. However all that said the things I don't like are a few.

For one, after you unfold it, it's hard to pick up and really awkward. While 50 pounds isn't super heavy, it isn't light. And I hurt my back a few times. When folded you have to make sure you fold it in the right order, folding the legs down first so it folds tighter. It can fold other ways that are less tight. This things is awkward to carry. It doesn't roll well, it's very tipsy. Rolling it up stairs is a good way to dislocated a shoulder. Carrying it is even harder, I wish there was an easy way to carry this upright.

If you clamp a pipe, you will flatten the pipe. There is no pipe holder, there are some V ridges, but it would be nice to have. The yellow sled is designed to come out and reverse. But it's so well engineered that the paint makes it very tight to remove, it's a tug of war to that thing out each time. I found oiling the bearings holding it in helps. Greasing the rails made a mess. There is no fine clamping force, the clamp is designed to sort of walk the yellow sled forward and it moves it in 1/2" increments.

I purchased this model because of the extra width for plywood sheets, and the back leg having a "foot" thinking it would be more stable on dirt. It is exactly that. It's rock solid. The only gig I have are the built in wheels for moving the unit. They are mounted too close together making it very unstable when rolling. Hardly worth mentioning.

My RK9002 was a Father's Day gift that came in response to strong hints. The box arrived intact but the unit did not work. The foot lever would advance the jaws but the jaws would not hold tension on a work piece. Close inspection of the mechanism revealed that the unit assembly at the factory had been VERY sloppy. A spare lock nut like the one used to secure the legs was rolling around inside the unit and lock nuts that secured the 10mm bolts used to assemble the locking mechanism were barely threaded onto their bolts. The steel rod that passes through the locking pawl was so far off center that the pawl would not grip the rod, even with the Lock / Unlock toggle was in the lock position. Even after adding some washers to help align the rod with the hole in the pawl and tightening the related nuts and bolts enough to produce alignment (but loose enough to allow free movement) the mechanism still would not operate Hands-Free, as advertised. There was still not enough return spring force available to move the locking pawl into locking position after the un-lock toggle released it. I ultimately added a helper spring to the pawl, to pull it upwards into lock position when the toggle was put in lock position. With an extra spring installed the unit began to function as advertised.

I think it is shameful that Rockwell is executing what is fundamentally a brilliant product concept so incredibly poorly. The unit is sturdy and looks likely to deliver excellent service for the rest of my life (now that I have it fixed). Maybe I should have boxed it back up and sent it back...I guess if it had not been a gift I might have...but I wanted them to see me use it.

The serial number on the unit suggests it was manufactured in 2013. At this writing in mid-2014, maybe Rockwell has gotten their act together. I don't know. I cannot recommend it to anyone who is unprepared to do the same fix I did. Without it, it simply did not work.
