How do you build a boat lift?


You need the following items to build a boat lift: 2 steel I beams, 4 inch x 10 foot, 2 steel I beams, 4 inch x 5 foot, 2 flat steel plates, 6 inches x 6 inches x 1/2 inch, cutting torch, welding machine, drill press, 1/2 inch steel bit, 2-sheave blocks, nylon line and steel eyebolts. Once you have the materials ready, cut one end of each of the 5-foot and 10-foot I beams at a 45-degree angle with the cutting torch. Weld together a 5-foot I beam and 10-foot I beam at the cut edges of the beams. Take additional I beams and repeat the welding process to form the davits (structure composed of two welded steel beams). Drill 1/2-inch holes using the drill press into each corner of both steel plates. Weld a flat steel plate to the bottom of each 10-foot beam. On the end of the 5-foot I beams also weld a steel eye bolt to be used to suspend the rive tackle. Bolt the davits to the dock walkway or pier. The davits need to be one boat-length apart, based on the length of your boat. With the line, reeve a twofold purchase in the blocks. Hang the blocks from the eye bolts on the davits. Fix an eye bolt into the forward structural member (the stem) and into the aft structural member (the main frame or transom frame) of your boat.
