Cone Roller for Sheet-Metal

In this video I make a sheet-metal slip roll for shaping cones and cylinders. The tool I made is quite small, but yet very rigid due to the variable width design. The design can of course be scaled for smaller or bigger, but add some chain or belt to make both lower rollers driving. The open end without bearings gives some new possibilities to use the roller, most still uncovered. The 3D Cad-model: The circle cutting guide idea is stolen from @TuomasSoikkelijyvaskyla
