Rubber Hose Chair

Step 2 Holes

Measure the diameter of the hose and its length. Calculate the spacing of the holes for the hose based on how long the hose is, i.e. how many back-and-forths the hose can make before you run out. Lay out the centers so that the edge of each hole is at least 3/8" below the edge of the plywood. Make the diameter of each hole 1/16" to 1/8" bigger than the hose to allow for movement. When drilling, go partway through the wood from one side, then flip it over and get the rest drilled out from the backside. This prevents the wood from chipping out and make ragged holes.

Lay out four holes for the threaded rods as well; one at each end of the "L", one at the crook of the "L", and one connecting the back legs near the bottom. Countersink the washers and nuts for a finished appearance. Try to keep the rods as far from the seating surface as possible so they do not interfere with the hose as it sags.
