Building a radio telescope

I have nema 17 motors. 2.5 mm bore I am looking for spure and gear for altitude and azimuth movements. I am driving these stepper from an Arduino with allegro motor Driver. I am familiar with electronics and programming but little less in mechanical althoe I have an idea of what I want. Ratio of 7 to one is ok. Any advise please?

Hi @Jatrottier and welcome to our forum!

Are you looking for a worm gear set similar to this one?

Unfortunately RobotShop does not have any smaller ones that could fit your NEMA17 motor. Also a ratio is a bit bigger than you need.

Let me know your opinion.
