It’s heavy-duty. Like all great cabinet saws, the Grizzly is built from parts that can last a lifetime or more. It has a cast-iron table, that’s precision-ground to be exactly level, with no warps or imperfections. The trunnion supports holding up the motor are also solid cast iron, which means that they don’t translate much vibration to the work surface at all. The paint on the cabinet and extension frames is powder-coated, and the miter gauge and riving knife are solid steel. Both extension table surfaces are made with a coated, engineered composite, which stands up well against dings or scuffs.
Makita joins DeWalt with an external riving knife release so you don’t have to reach into the throat to loosen it. We actually ran into an issue with the design because of a slightly bent plate holding the knife in place. That aside, the intent of the design is sound and should make for an an easier experience. Because of the external release, Makita screws down the throat plate in place. You should only need to get in there for blade changes if everything functions properly.
The GTS1031 is Bosch's newest table saw, designed for portability and intended to be light enough that you could carry it with one hand. Its rip fence is designed for quick and easy movement, and clamps into channels on opposite sides of the table to keep things consistently square without the need for frequent adjustment. Two notable advantages for the GTS1031: Its 5000 RPM max no-load speed compared to the 3850 RPM for the DeWalt, and the fact that you can use a 1/2-inch dado set with it (though it requires separate TS1013 dado throat insert).
It’s highly portable. Even though the whole body feels sturdier than the Dewalt’s, it’s still relatively light, at just about 60 pounds. There are handles in both the top and bottom edges of the machine, for easy lifting, and once you’ve got the saw fixed to the base, you won’t have to lift it on your own except for when you’re loading it in the back of the truck/van.
The more table size you have, the more support you have which is always a plus, not only for convenience but safety too. There are right side extensions that can be purchased for table saws that increase the table saw’s capacity to get to the center of a 4 x 8 sheet of wood. Although most saws have a rear band that supports the wood as it exits the saw, an additional safety measure is to rig up an outfeed support of some kind in addition to this rear bar. Be sure that the outfeed support you set up is ¼” lower than the table saw is.
We evaluated the flatness of the table by measuring the flatness by placing the edge of a precision ground flat bar across the table and placed feeler gauges in any gaps to measure any difference between the ground bar and the table. TBB took measurements in four directions. As the operator faces the saw, we measured the flatness at the arbor from front-to-rear; we measured the left-to right flatness at the arbor; we measured the flatness from the upper left-to-lower right table corners; and, finally, we measured the upper right-to-lower left flatness between the corners.
