You can sharpen, grind, cut threads and perform other work on a lathe. But this is expensive, bulky equipment that not everyone can afford. For a home craftsman, a simplified homemade machine is often enough. It is easy to make in a garage from available materials.
What you will need:
- Steel pipe 50 mm;
- bearings with an inner race of 50 mm – 2 pcs.;
- washing machine motor;
- drive belt;
- M8 nuts – 6 pcs.;
- M8 bolts – 6 pcs.;
- profile pipe 40 mm;
- corner 15x15 mm.
The process of making a simple lathe for a workshop
To make a machine chuck, you will need a piece of pipe with a diameter of 50 mm and a length of about 20 cm.
It needs to be cleaned from the top.
Along the edges of the pipe you need to mark 3 holes with equal separation from each other. The marks are drilled.

Then a pair of bearings are placed on the pipe.
After this, nuts are welded onto the holes along the edges. At the time of welding, they need to be held with a pin so that they have the correct direction.
Next, we take a profile pipe and weld two pieces of angle to it across it. We are already preparing the upper bearing races for them. Thus, we obtain reliable fastening of the cartridge.

A corner is welded to the same profile pipe, to which the electric motor is screwed. It is better to immediately put on the drive belt before cooking to get the desired tension.
Now we screw the bolts into the cartridge. By pressing them, you can fix workpieces of almost any length. The rotation of the machine due to the bearings is carried out without runout.
You can sharpen the workpiece wrapped in it with a grinder, file or other tool.
