To build a hydraulic coil, you will first need some supplies: an electric motor, shafts and bearings, clamps, wire and connectors, tubing, and fittings. After supplies are gathered, you will begin by creating the basic design of your coil. You will need two shafts that will connect together to create the rotational motion of your coil. You will also need two bearings to keep the shafts in place and help with the rotation of your coil. Finally, you will need clamps to secure the bearing assemblies to the shafts.
