Miter Saw / November 30, 2018 / Tina Abrahamsson
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.
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.
The saw must be mounted in this gap so that the top of the miter saw table is flush with the top of the saw table. The miter handle must be free to move its full travel in both directions left to right. Anticipate the need for this gap as you are framing the underside of your miter saw table because you will need to construct a shelf underneath to support the weight of the miter saw. You might want to make this shelf adjustable in micro increments so that you can get the top of the saw platform exactly flush to the top of the saw table. You can do this with lag screws with washers in sliding slots through the shelf sub-structure and into the table framing. Slightly loosen the lags and tap the table up or down with a rubber hammer before tightening the lags fully.
