So I have 2 jet impellers and 1 motor lying around that I have not used on anything. Therefore I decided to design a unit that utilises the parts. Here is the first iteration of what I have come up with:

Nice. How would you drive them? A miniature dual output helical gearbox would be ideal. Not sure if there is such a thing? Belt drive would be “simple stupid”.

I’ll probably start with simple direct drive gears made from delrin. If they work well then great, if they don’t I’ll move to a heavier material like aluminium. I don’t really see a need for helical gears. I can gear the motor down slightly to only put 16000rpm through the impellers. A belt drive would mean I need tensioners which I’d like to avoid.

Bahahaha “Special” mast clamp design coming shortly. I even know where the water inlet pipe will be 😉
