The next step is to make a bottom guide to support the nail file. It will be installed under the sole. The guide is made of three bearings.
Of these, two support the canvas on the sides, and one prevents it from deflecting towards the edge. The base of the guide is bent from the strip, onto which rods are welded, machined to the inner diameter of the bearings. It is made in such a shape that it can be installed in the standard lugs from the dismantled mechanisms under the sole of the machine.
