Vac-Attack lets you take on cleanup like never before — a hand-powered vacuum driven by a high-speed gear transmission. At the core is a staggered spur-gear train with a 1:3 ratio at each stage. A 30-tooth gear drives a 10-tooth gear, tripling the speed. This setup is repeated five times, producing an overall input-to-output ratio of 1:81. In other words:For every single turn of the crank, the impeller spins 81 times.Crank at 30 RPM, and the impeller reaches 2,430 RPM. Required hardware:608 bearings ×7Because of the high rotational speeds, only non-3D-printed bearings are recommended. Happy vacuuming 🌀 Buy Me a Coffee Boost MeFuel the fun
