For anyone else who got stuck at 4:16 where the length of pi is put in, I think that this value is (pi * module). Since the module in this example is 1 (pitch diameter = 12 / 12 gear teeth). Using pi * module seemed to work for me :)
I understand some of the concepts, but it is like watching a brain surgeon perform surgery, I'm not ready to try it myself. Great job and thanks for sharing the magic
Hi David, Well it can be quite confusing! There are many books that describe how gears are designed and the math behind it. In making this video, I decided to attempt to use minimal math and more methodology. Thanks you, and as always, you are very welcome! Greg
Nice video! A couple things: In fusion 360, you can press 'shift + n' to automatically make all of the components different colours. It helps with distinguishing different bodies. I've been trying to just use gear teeth shaped like triangles. I'd imagine they have more friction than the properly shapes ones, but they're a lot simpler to make in CAD, and they're good enough for hobby-level projects. Good luck with future projects!
In 3:00 I have a problem because in my sketch the circle is blue and in yours is black. But when is the circle blue they didn't holds the same position and when I creating the first rack tooth the circle moves away the line of the rack tooth. Pls help.

That is correct carinthesunset1971, it is (pi * module) which in this case was 1, but thank you for helping me!

Ahh finally, thank you bro this is exactly what I've been looking for! Epic tutorial 🙌
You're very welcome, I'm very glad it helped!

Hi Evan,
Thank you, I'm glad you enjoyed it, and thanks for the tip!
Greg
Nice project! More complex than I hoped for, sosome study required..😉Thank you.
Hi W.P. Ginfo,
Thank you! It is indeed complex, it took me quite awhile to grasp the basic concepts.
Greg
Thank you! More like this, please!
You're welcome!

I just checked the price of Autodesk Fusion 360. I think I might be sticking with TinkerCad for a bit longer 😆 Still fascinating to watch you work 👍
Hi GrandadsOtherChannel!
I use the "free" or "personal use" version.
Greg
@@popzct 😊💰
I'm pretty sure it's free for students and hobbyists. You just have to go looking for the free version a little.
What reasons do you have for not using a gear generator? There are a number of free plugins and add-ons that can manage gear racks.
Hi TheOfficialCzex,
I enjoy the mathematics behind it all.

Hi Daniel,
Note I carefully draw that circle from the center point to the end of the pressure angle line that I had previously trimmed.
