Cement Mixer Kit
A 37-gallon tipping drum on a wheeled A-frame, its electric motor in a housing at the back. Set it up and it is a Cement Mixer: the same sand, stone and water as the bench takes for concrete and mortar, mixed in the drum in a fraction of the time. The motor draws about 650 W while it turns, so it needs a live grid. Use it to place.
