Self-made lathe: how to make your own hands?
To make homemade at homea lathe, you do not even need drawings. But on this device you can make cute coasters, pens for different tools and much more.
Homemade lathe can be made,having picked up for this purpose an electric motor, a wooden block, a wooden board, a head 9/32 from a set of tools, a bolt M 12 with two nuts. After you have purchased all the necessary components, you can proceed with the assembly of the structure.
As the motor the motor will approach,removed from an old sewing machine, because there is a pedal that regulates the speed of rotation. As a workpiece for the cartridge is suitable head 9/32, which is fixed to the shaft with the help of cold welding or epoxy glue. The electric motor can be fixed on a wooden bar, screwing it with screws or by means of cold welding. You can use a two-component instant glue, which is well lubricated by the bottom of the electric motor, and a wooden block is applied to it. In order for the parts to stick together well, they need to be fixed in the folded state (until the glue polymerizes). After the parts are firmly glued together, they must be mounted on a wooden board, which will be a bed. The tailstock is cut from a wooden bar having an L-shape. It is mounted on the board-stand opposite the electric motor and fixed with screws. The M12 bolt is screwed into the improvised tailstock, on both sides its position is fixed with nuts. The end of the bolt must be made conical. This can be done with an electric drill. The bolt is clamped in it, and then with the help of the file the cone on the bolt is brought. And here the self-made lathe is ready for work.
You can try it by turning the woodenworkpiece. To do this, it needs to be given a six- or octagonal shape, nakernit on the one side a hole for the tailstock bolt, and on the other, drill a hole that is slightly smaller than the diameter of the head 9/32. The workpiece is inserted into the cartridge and pressed with the tailstock. Then the engine starts, which rotates the workpiece. Now you can start processing it. For work, do not forget about safety. Processing of the workpiece should be carried out in protective glasses. Do not stop the rotating workpiece by hand!
Homemade design for turning metal
Homemade metal lathe differsfrom the previous design more complex device. It has a rigid metal frame of channels, which is its bed. At the left end of this frame is fixed a fixed headstock, and on the right end a support is made. In such a machine tool, there is already a spindle with a mounted chuck or faceplate attached to it. Rotation to the spindle is transmitted by means of a V-belt drive from the electric motor. If in the previous case the cutter had to be held by hand, then when turning the metal, this can not be done. Here there are such loads that you can not simply keep the cutter. Therefore, the self-made lathe is equipped with a support that can move along the longitudinal axis. It is equipped with a toolholder that can move in a direction transverse with respect to the movement line of the support. You can control its movement with the help of a handwheel, on which a ring with divisions is installed. Handwheel rotates by hand.
Ability to install CNC
You can make a self-made lathe with numerical control,using two stepper motors and any control board of stepper motors in 2-3 axes. It is very suitable for turning woodwork.
