Rockwell Jawhorse RK9109 Plywood Jaw Accessory Attachment Reviews
This accessory is simply a replacement jaw for the one that comes with the Jawhorse. I have found it to be quite useful and it isn’t so large as to represent a storage headache. It has a significantly wider throat than the basic jaw and so can’t be reversed. It also has a wider base, but not so much as to provide additional lateral support. It’s very easy to remove and reinstall either this or the basic jaw on the Jawhorse, so that’s not an issue.
For working with a 4×8 piece of plywood you need to do something to support the overhang (hardly surprising). 2 clamps are included to construct outriggers using either 2×2 or 2×4 stock to serve this purpose (think in terms of an 8 foot piece with a leg clamped on each end … the cross piece is laid across the inside of the jaw to provide the support). It’s a simple jig to create and is more effective than some of the silly things I’ve done using saw horses in the past.
I am a very happy user of the JawHorse, and the plywood jaws live up to the same quality standard.
The Plywood jaw is just a longer jaw with the same heavy-duty construction as the normal JawHorse jaw. It’s easy to install aned works well. Includes connectors to quickly add outriggers made from 2X4′s (you supply the 2X4′s).
I am highly charged on this tool system, It is built very very well and highly useful and Ingeniously designed to serve many functions that are able to be done with other tools but those tools (I own most of them) do not do the jobs with the strong simple approach of this tool. You will find many uses for it that even the inventor probably didn’t see.
I purchased the Jawhorse and all of its accessories and have used them all. The Jawhorse does everything that it advertises and is a solidly built tool. There are many possible uses for this that I have not even thought of yet. It is like having an assistant for complicated jobs.
