Step 1: Get Materials
What you will need: 100ft of rope, 4 2"x2"x96" wood planks, 1 box of 2 1/2 inch screws, a 5/8 inch drill press bit.
Step 2: Cut Your Wood
You will need to make the base of your bench, as well as 4 legs. For the base of the bench you will need 4 pieces of wood: 2 at 48 in and 2 at 22 in. Once the wood is cut to the desired length, you will need to cut at a 45 degree angle at the ends of all the pieces for the base of the bench. Make sure that when you cut your wood at the angle it looks like a trapezoid and not a rhombus. Then once you have your base cut, you will need to cut the legs. Each leg should be 19 in.
Step 3: Make Your Holes
Next you will need to make your holes so the rope can be thread through. You will need the 5/8 in drill press bit for this step. First, you will have to measure the spot where the leg is on the base of the wood. This is because you cant make holes here because the leg will block the rope from going through. Next you must measure and make a mark every 1.5 in. After that you must measure 1.75 in up from the bottom of your base pieces, this will be where you drill the holes. Go over to the drill press and make a hole at each intersection of the lines. Once you have done that for each base piece youre ready to assemble and thread.
Step 4: Assemble the Bench
Now you will need to screw the legs onto the sides (smaller base pieces) of the bench. Once the legs are screwed to the side pieces, you need to match up the side pieces to the front and back pieces. Then you must screw those pieces together, and also add a screw from the front and back pieces to the legs for added support. You should end up with a rectangle and 4 legs sticking up.
Step 5: Threading and Finishing
Finally you are ready to thread. Take your rope and measure out how much you will need (Rope should go through each hole and the length may vary due to some human error). Once you have the length measured, add 5 more inches of rope just in case of any miscalculations. Tie a knot to one end of your rope and start to thread in and out. Make sure to pull as tight as possible while threading to keep the tension up.
