A lathe in skilled hands can work wonders. Of course, in order to grind an uncomplicated cylindrical part on a machine, high qualifications are not required. But what if you have to make wooden rings, for example, but you don't have a lathe at hand? Here you cannot do without professional tricks and skill. However, you will also need an electric drill.

Select a blank suitable for making rings. It can be a rounded thick stick or a twig. Raw material lends itself better to processing. Much will also depend on the type of wood. Opt for black walnut, beech, birch or maple. Very good rings will come from a fresh apple tree. If you want to get a product that is beautiful in color, with streaks, use the rowan kernel, although it is more capricious and requires careful handling.
Make a mandrel that will be attached to the drill for processing rings. For such a mandrel, use a wooden cylinder with a diameter of 30-40 mm and a length of 45 mm. Attach the arbor to the shank of the electric drill, pushing it tightly onto the spindle.
Make a stop for the cutting tool, adjusting it in height so that the sharpening tool is level with the axis of the drill spindle.
Use a small round cutter to punch a hole about 15 mm deep in the arbor. Tapered the walls of the hole formed using a knife. Insert the workpiece with force into this hole. Cut several 5 mm thick circles from the workpiece (according to the number of rings).
Strengthen the circle in the mandrel and flatten it along the plane of the butt by hitting a small hammer. If the diameter of the mandrel hole is less than the diameter of the circle, wrap the circle with one or two layers of paper.
Attach the drill with clamps to a chair, stool or table (workbench). Use a small chisel to drill a hole in the circle and bore it to the desired size. At the same time, turn on the drill with short impulses with the left hand and only during the turning of the part. If the first time the ring does not work out the way you would like, do not despair. Mastery comes with experience.
Finish the rings with the tip of a sharp knife, removing the inner chamfer. Finish all surfaces of the rings (external and internal) with sandpaper of different grain sizes, from coarse to fine-grained.
