Our linear launcher (not actually a puncher, but similar) uses aluminum extrusion with those same dimensions as its main structure, and our winch gear system is integrated, so our aluminum box structure serves both as a gearbox and launcher track all in one piece. Since our launcher stores a ridiculous amount of energy, we now understand that these types of ball shooting mechanisms may just need that much structure!
