The miter saw is one of the most useful power tools in any shop or garage. Its ability to make multiple angled cuts makes it essential for installing crown molding, and with its pivoting head, making multiple-length cuts is quick and efficient. The drawback to this tool, however, is its bulk. Building a miter saw workbench only increases its usefulness.
Measure and lay out the 2-by-4-inch boards for legs and stringers using the tape measure and pencil. The four legs will be 31 inches long, four side stringers will be 20 inches long, the inside stringers will be 17 inches long and the front and back stringers will be 8 feet long.
Measure and cut the 3/4-inch plywood into two strips, 20 inches wide by 8 feet long using the circular saw.
Attach the legs to the front 8-foot stringers using the drill, Phillips-head bit and two 3-inch screws per face. Screw the 4-inch side of the stringer to the 2 inch side of the leg, making sure to keep all edges flush and sink the screws.
Measure from the bottom of the leg up 8 inches and make a mark to indicate the bottom edge of the lower stringer.
Attach the lower stringers on both sets of legs with two 3-inch screws on each face. Be sure to keep the lower edge of the stringer on line with your mark and flush with the outside edge.
Stand both sets of legs up and attach side stringers to the outside of each leg using two 3-inch screws; connecting both sets. Start at the top and flush the end of the side stringer with the outside edge of the front stringer. Repeat this for all four side stringers.
Measure from the outside edge of the table across the front and back stringers 32 3/4 inches and 64 3/4 inches making a mark followed by an X (there will be eight marks total).
Line the outside edge of the inside stringer with each mark covering the X and attach each of the four inside stringers using two 3-inch screws on each end.
Place the 3/4 inch plywood on top of each level. You will need to cut a notch 1 1/2 inches by 3 1/2 inches in the plywood for the bottom level for each leg.
Attach the plywood with 1 5/8 screws. Use three screws on each of the short stringer and five screws on each of the long stringer.
Place the mitre saw in the center of the top table and mark for each of the bolt holes in the frame of the saw.
Remove the saw and drill the holes with the 3/8 inch drill bit.
Replace the saw and run the bolts up from the bottom of the table and tighten the bolts and nuts down using the 9/16 inch socket or wrench. Running the bolts from the bottom up allow the carriage head to dig and lock into the wood.
Measure the height from the plywood table to the top of the mitre saw cutting table.
Rip two blocks 20 inches long to the height difference using the circular saw.
Attach these block over top of the inside stringer using three 3 inch screws.
