Windshield wipers motor

[seandepagnier]

I know people who used those teeth with that belt and it slips with any amount of weather helm.   It works in some conditions though.

It will depend on your boat and rudder but in any case you will find out.    I managed to 3d print the larger pulley with the correct teeth but  my printer was slightly incorrect  0.5mm wider over a 180mm wide circle  which made the teeth slip on one tooth out of 120.    I need to calibrate the obliquity in the printer (delta style) to properly print pulleys with more than 100 teeth and got sidetracked.

I can post my 3d files for pulleys if you like,  modified from thingiverse ones I found.    In any case.  the wiper motors are generally reasonably waterproof to begin with but additional protection is a great idea.   It looks good.

Hi Sean!

Thanks for reply. Yes, please post your 3D files, but I use Fusion 360, and hence not sure I will be able to see your files. In case it is STL files, then it is a different story.

In case idea with the belt and windshield wipers motor doesn't work, what would you recommend? Maybe another kind of motor?

Thanks for reply,

Gennady

I use openscad.    Not sure about fusion 360 but I put an stl file.   The issue is you cannot easily edit it.

The belt and wiper motor should be good,  I just suggest toothed pulleys that match the belt teeth.
