DIY Rotomolding

Rotomolding is used to create hollow forms by slowing rotating a mold while the material covers and hardens to the shape of the mold. [ds] built this version using a stepper motor to drive the assembly and a belt drive link An extreme version is used to form whitewater kayaks and other plastics. This thread over at cnczone has a rotisserie oven version that looks ideal for small plastic or wax molding.
there was a history channel documentary about chocolates or something, they use the same technique to make hollow chocolate rabbits and stuff,
A clean and neat presentation, awesome work!
im kinda surprised 4rpm works well, i expected it to be much faster to distribute resins
