starting RB7s rims
Today it goes on with the rims. It’s an eerie stressful and extensive work to produce such a modern rim out of paperboard. The rear ones are semi finished (valve and lacquer are missing), at the front, the star of spokes’s missing (only the star at the rear rims consits out of 48 parts). But the work pays off if you look at the achievement at the rear axle. The regulated width of 180cm is reached at the rear, at the front it maybe could exceed because of the 4° camber angle (we’ll see that after completion). I’ve considered that in my calculations, but the manufacturing of the components out of paperboard never can be so accurate like the construction – I’ve to calculate with a tolerance of about +/-0,3mm.
