Let's Make Robots!

Help needed with an unusual stepper motor coupling

 

Hello all.

I'm completely new to your world and am building a kind of robot that's a bit out of your usual line - this robot makes vodka!

Seriously, I'm an experienced amateur distiller in New Zealand - where home distilling is perfectly legal.  I build my own stills as well as use them.

My latest project is to build a completely electronically controlled vodka still of the kind available to major distilleries ( at huge cost ) on a hobbyist budget.
