Instead of cans you can use a thin sheet of metal and make from it 4 disks with an outer diameter of 200 mm and 4 with an inner diameter. 170 mm. Bolt the small discs together with the large discs in pairs. Attach four knives each to these disc structures.

The frame to be assembled with my own hands. The equipment consists of an upper crossbar (10) and a metal strip with corners and grommets (16). For the crossbar you can take a metal angle of 35×35 mm. The cylinders are connected by a belt, for the installation of which grooves 13 mm wide are drilled into the corners. For the same purpose, the lower drive drum sleeve is movably mounted on the bar (15), and tensioning brackets (20) are installed on the upper axes of the cylinders. To the ends of the crossbar pulling angles (20) with screws M5x65 mm.
