One of the many reasons I got a Glowforge was to be able to cut gears. So I started playing with planetary gears
This one I made yesterday and today I started working on a double one
This one should give a 1:25 ratio, I’ll post a video once I get it working, I neglected gravity when I drew it so it doesn’t stay together

Love it! I find that gravity can be a problem sometimes too.

Gravity is consistent but not always your friend.
Try some clear acrylic and sandwich things together, too cool to let gravity win

That’s my plan, it won’t win, it just snuck up on me!

I managed to hold everything together so I added a third set:slight_smile:

I really can’t believe it still worked with the third set, it’s all MDF which isn’t the most slippery stuff and there are no bearings, just nuts and bolts holding it together!

Awesome! That’s on my list for the one at work, just haven’t made it that far yet

Nice! Have you figured out the ratio on that iteration?

1:125 says the math and reality :-0

I thought that was for the two level. wouldn’t adding a third change that?

First one was 1:25. This one multipled it by 5 again to 1:125

Cool! FWIW, waxy lubes and graphite tend to work on mdf.

Really cool concept. Thanks for sharing. What program did you use to generate the gears? Did you use the paid geargenerator site or something else? I want to make some gears and i’m wondering if there are any open-source or free options.

Affinity Designer includes gears in its shape-drawing tool.
