To assemble a homemade lathe at home, you don't even need drawings. But on this device you can make cute coasters, handles for various tools and much more.
A homemade lathe can be made by selecting for this an electric motor, a wooden block, a wooden board, a 9/32 head from a tool kit, an M 12 bolt with two nuts. After all the necessary components are purchased, you can begin to assemble the structure.
An electric motor taken from an old sewing machine is suitable as a motor, since there is a pedal that controls the speed of rotation. As a blank for the cartridge, a 9/32 head is suitable, which is fixed to the shaft using cold welding or epoxy glue. The electric motor can be mounted on a wooden block by screwing it with screws or by cold welding. You can use a two-component instant glue, which is well smeared with the bottom of the electric motor, and a wooden block is superimposed on it. In order for the parts to stick together well, they needfix in the folded state (until the glue polymerizes). After the parts are securely glued together, they must be installed on a wooden board, which will be the bed. The tailstock is cut from a wooden bar that has an L-shape. It is mounted on a board-bed opposite the electric motor and secured with screws. An M 12 bolt is screwed into the impromptu tailstock, and its position is fixed on both sides with nuts. The end of the bolt must be tapered. This can be done with an electric drill. The bolt is clamped in it, and then a cone on the bolt is brought with a file. And now the homemade lathe is ready to go.
You can try it by turning a piece of wood. To do this, she needs to give a six- or octagonal shape, punch a hole for the tailstock bolt in the center on one side, and drill a hole on the other, which will be slightly smaller than the diameter of the 9/32 head. The workpiece is inserted into the chuck and pressed by the tailstock. Next, the engine is started, which rotates the workpiece. Now you can start processing it. For work, do not forget about safety. Workpiece processing must be carried out in protective glasses. Never stop a rotating workpiece by hand!
Homemade design for metal turning
A homemade metal lathe differs from the previous design in a more complex device. It has a rigid metal frame made of channels, which is its bed. At the left end of thisframe, a fixed headstock is strengthened, and a support is made at the right end. Such a machine already has a spindle with a driver chuck or faceplate mounted on it. Rotation is transmitted to the spindle by means of a V-belt transmission from an electric motor. If in the previous case the cutter had to be held by hand, then this cannot be done when turning metal. Here there are such loads that you simply cannot hold the cutter with your hands. Therefore, a homemade lathe is equipped with a caliper that can move along the longitudinal axis. A tool holder is installed on it, which can move in a direction transverse to the line of movement of the caliper. You can control its movement with the help of a handwheel, on which a ring with divisions is installed. The handwheel is turned by hand.
Possibility to install CNC
You can make a homemade CNC lathe using two stepper motors and any board to control stepper motors in 2-3 axes. It is very suitable for wood turning. Given that such a machine in the store will cost a decent amount, it makes sense to do it yourself!
