[BW] GR-01 Build Diary

Eggbeaters are generally much easier to make - it depends what methods you use. I get beaters cut from steel plate by water jetting and then have axles turned on each end by the same company - all I have to do is draw the part and throw cash at them . To make a beater yourself is still easier than a drum but requires a mill. If you use a hardened steel like Hardox (highly recommended), you will also need carbide cutters.

Beaters have other advantages over drums:
* one piece construction - no screws or welds to break.
* Higher kinetic energy for the same weight & diameter. The beater keeps most of its weight at the perimeter for efficiency.
* More tooth bite. The beater is usually better when going head-to-head against a similar drum.

The main disadvantage is poor aerodynamics. The beater acts like a fan and requires a larger motor and battery compared to a drum.

I wonder if this could've solved by making 2 half drums out of say fibre glass and bolting them on to an eggbeater, effectively making it a drum but without using the drum for structural purposes. They might even let you into the drum-off!

I already tried that and it didn't go well at all! The centrifugal force threw the drum halves off the beater, which managed to cut one half to shreds.
