Question: Is this miter gauge major overkill for a Dewalt 7491 portable contractor's saw?  The miter supplied with the Dewalt saw should be recycled ASAP.
Document: I own a Ryobi Portable Table saw BTS20. Not the best, but not the worst either. As most lower cost table saws cross slide wobbled in the groove. In addition setting angles was iffy at best. The cast in indents at the several supplied presets were not exact and setting accurate angles between presets was not possible. I could not get accurate and repeatable cuts. OK for house construction but forget it for cabinet work. Bought the Incra 1000Se. Corrected problem nicely.
When I bought my table saw, and being a rank novice at what to expect from the supplied Miter Gauge, I actually got the supplier of the saw to send another Miter Gauge because the originally suppled Gauge was, as  I later learned, ONLY good for framing use and produced irreproducible cuts.When you buy a Table Saw, regardless of manufacturer, at the same time, buy this Incra Miter Gauge, and don't even TRY to use the one supplied with the Saw.
This is a very good miter gauge for the money. The Dual Flip Shop Stop accessory is especially versatile & easy to use and the miter slot adjustment is easy. The fence is a very versatile design also, and is square to the saw table. On the other hand, certain of the allen adjustment bolts rust very quickly in a humid environment. Also, for adjustments you need to keep the allen wrench (supplied with the gauge) handy.You may want to add an auxiliary fence face.
This product is well made and accurate. It has one really bad feature which is true of any miter gauge you use on a home or portable size table saw. Your limited by the amount of space on your table saw between the leading edge and the saw blade.If you try to use it to cut a piece of wood that is wider then the space between your blade and the leading edge (edge closest to the user) the miter gauge over hangs the front of the table and is totally useless.
Nice gauge. Easy to assemble and calibrate. Constructed very well and should serve many moons. One drawback for me is that it is very heavy around the handle and with me trying to use this with a portable table saw it is really too big. My saw does not have the T-slot gauge so if I try to cut wide boards the gauge wants to come out of the slot. Not the fault of the gauge, just my small table saw.
It's heavy and solid. It's precise. Confidently make miter cuts, cross cuts. The stop shop makes repeat cuts easy. The miter bar's expansion disc (3 factory installed, you can add 3 more discs which is supplied) makes for an easy, smooth and perfect fit on the table saw miter slot.
And you have to use a tool (supplied) to make fine adjustments. Incra should really come up with a tool-less way to make adjustments, and just have two seperate flip stops instead of tethering one to the other.I haven't decided whether I can live with this or return it, but my advice is to look hard at this and other miter gages before you purchace this one. For $150 I expeced much better.
I purchased some Incra products in the past and their products are made very well and do exactly what they claim to do. Everything is always supplied with their products and there are always extra nuts and bolts and the appropriate driver needed to use their products. When I am ready to purchase a tool and incra makes what I need, I always use their product to judge the others.
Great miter gauge. Easy to setup with included instructions. Once set up to the saw it produces incredibly consistent miter cuts. Must have for any table saw.
miter gauge is very well built. came in excellent condition and was easy to assemble and adjust to my saw. I was realy impressed with the addition of replacement parts for the slide.
