JawHorse Rockwell 866/514-7625 rockwelltools.com Street price: $180 Regular Tool Kit readers might remember that I raved in the November issue about the virtues of lightweight tools. I’m taking a different tack now. On my bathroom scale, a single JawHorse weighs 45 pounds. But in this case, the weight’s a good thing — sawhorses with heft don’t move around, particularly when supporting heavy deck materials. Plus, each JawHorse is rated for a 300-pound load. Another factor that contributes to the JawHorse’s stability is the three-legged design, which is great for the uneven ground deck builders tend to work on (Figure 1). It would be even better if one of those legs were adjustable — for leveling the horse — but that’s nit picking. You might think that at 45 pounds each, the horses would be a chore to move, but they’re not. Folded up, the single leg acts as a carry handle (Figure 2); be a little careful here — the knob that clamps the leg in position has to be tightened firmly, or the leg could slip and the horse open up in midcarry. On smooth surfaces, you can swing that leg out of the carry-handle position and use it to pull the JawHorse along on its integral roller. Folded up, the horses stand on end, storing in a very small footprint. Still, there are lighter, less expensive folding sawhorses on the market that do a great job supporting heavy loads. What sets JawHorses apart is their clamping ability. A foot pedal located between the two front legs tightens a deep, padded pair of jaws (Figure 3). Holding stock firmly is key in making the cuts that count. The jaws move easily and clamp with up to 1 ton of force, according to Rockwell. That clamping ability combined with the weight of the JawHorse is great for initially steadying posts on footings while you’re preparing to brace them plumb. The JawHorse would halve the manpower normally required for this two-person job. The jaw is reversible, which provides a clamping depth of 37 inches (Figure 4). Several optional accessories add to the Jaw Horse’s utility. An extra $50 buys an extended jaw that clamps boards up to 52 inches in width. Work with logs or big timbers? $40 buys a set of serrated jaws said to handle logs up to 12 inches in diameter. Perhaps more useful to most deck builders is the $80 miter-saw station (Figure 5). While not as well-suited to the job as a true dedicated saw stand, this rig sure adds to the utility of the JawHorses. The table where the saw would sit, along with a 2x4 of any length you choose, clamps into one JawHorse. Adjustable-height outfeed rollers clamp to the 2x4. If you’re handling heavy material, you should support the ends of the 2x4 with a couple of legs made from, you guessed it, 2x4. Included clamps make this attachment. The only bad news is the $180 price (each). Nonetheless, deck builders who grit their teeth and spend the money will be glad they did — especially if they work alone — every time they use the tool.
