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.
With a 32½" rip capacity and motor capable of up to 4800 rpm, the DWE7491RS is more than prepared to effectively deliver 3⅛" deep cuts to thick slabs of wood. Happy customers sing this machine’s praises, reporting that it’s as sturdy as a table saw can get — plus, it’s easy to use, and assembling it is a cinch. They do however note that workers looking to produce finer cuts should seek out a replacement blade since the one provided is more suited for fast, rough work.
