Miter Saw / October 29, 2018 / Fiore Calabrese.
Use a long straightedge in all directions to make sure that the miter saw and the miter saw table are flush with each other. Mount the saw securely to the shelf using lag screws. Once the miter saw is mounted you can begin to construct the fence or fences. A simple inexpensive fence can be constructed using 1 x 4 or 1 x 6 clear fir boards. These boards should be hand selected for straightness and jointed on one edge. One board will be the actual fence and the other will keep it straight from behind. The fence sits with its jointed edge on the saw table top while the back-up board lies flat on the table behind the fence with its jointed edge joined to the bottom of the fence.
This also allows you to push the tool directly against a wall for use with literally zero clearance behind it and because the saw is insanely compact (weighing only 65 lbs) its simple to use in cramped low-space work-spaces and convenient to store and transport. In place of the sliding rail interface of former saws 12 sealed ball bearings make up the GCM12SDs new enclosed system one that maintains its integrity for essentially all-time providing the smoothest blade movement and vastly better control. Because this system is also enclosed its bearings and rollers wont accumulate jobsite debris thus ensuring it remains with a glide like nobodys business for its entire life-cycle. The thing also features a glide damper allowing you to adjust the saws resistance changing the "glide" mechanism as you see fit. Built with a totally transparent lower guard the saw additionally ensures youll have completely unimpaired visibility through each cut.
The saws all metal bevel lock lever and range selector are also integrated perfectly into the front of the saw eliminating the need for users to crawl around the thing to make adjustments. The tools soft-grip trigger handle is also ergonomic and ambidextrous for the most comfortable use for every craftsman. The GCM12SD additionally boasts Boschs high-precision Squarelock fence famous for requiring no adjustments its one touch lock/unlock slide and its always stable fence support. Precision machining also ensures the two-piece fence is always aligned to the table top at exactly 90° to produce cuts accurate enough to predict the weather (so to speak). Each side of the miter saw also sports integrated expanding base extensions or material supports that pull-out and lock into position to provide 40 inches left-to-right material support - thats a full 60% more than the leading competitor.
A fence can be attached to the back side of the 4 x 4. Use a 1 x 6 or 1 x 8 clear fir board for this purpose. As in the permanent table above the front of the fence must align perfectly with the miter saws metal fence. If a wider support surface is needed a second 4 x 4 can be mounted directly in front of the one with the fence attached to it. A Kreg Trak system with a flip-up stop can also be used on this portable miter saw table. Just make sure the wooden fence is ripped to the proper height to allow the flip-up stop to clear the table by 1/16". (Fence is 2 1/4" + above the top of the 4 x 4.) As for the support table I have used a plastic fold-up table from Costco. They come in various sizes to suit your particular need. Or you can make your own table out of 2 x 4s and 3/4" plywood. Design it so that the legs can fold up for transportation and storage.
