[QUOTE="Greenhornet_au, post: 482739, member: 8767"] I think that design for the slanted Cab machine is awesome, and I'm itching to build one for the kids. Basically wooden block and motor bolted to it, plastic tub and a window washer pump - compact and cheap To make it a 12Vdc portable unit is a great idea but you need a good high speed and good torque 12VDC motor with a speed controller. ($8 - $15 Fleabay) For the motor think car wrecking yards / auto electricians (for info on what to look for), generators (not alternators). In the past I have seen them used on 12VDC Duck pluckers in the field. Wiper motors are all geared down, great torque but no speed. Maybe even something like a DC cheap cordless angle grinder with a speed controller? But most are not 12Vdc but 18-24Vdc. Great project. :clap: [/QUOTE]
