With this homemade product you can, using a conventional cordless screwdriver, quickly drill a large number of holes in wooden blocks. A distinctive feature of this device is its low cost and high productivity.

Preparatory work

First you need to make a special adapter on the lathe for a screwdriver, on which there will be a chuck from the drilling machine (or mains electric drill). Further, from a pipe of a suitable diameter, it will be necessary to make a cage for the bearing.
Also for the manufacture of this device you will need: a steel plate of rectangular shape with a length of 14 cm and a width of 5 cm, two steel rods of circular cross section 29 cm long, two powerful springs 15 cm long, as well as a bearing and two pipe sections 4 cm long.

Three holes must be drilled in a rectangular plate (two at the edges and one in the middle, which are located on the same axial line). A steel square plate, in which you need to drill a through central hole, is suitable as the base of the entire structure.

Construction assembly process

Two vertical posts of steel bars must be welded to the base of the plate, and two pieces of pipe 4 cm long should be welded along the edges of the rectangular plate. A metal cage for the bearing is welded in the central part of the workpiece.

Also, to the edge of the base of the plate, you need to weld another segment of the steel bar at an angle of 50-60 degrees. Then all places of the welds are cleaned with a grinder, and the main structural elements can be painted. The step-by-step process of assembling this device, as well as its application, see the video on our website.
