another great lock in, the cad is done (finally). V2 seems like it could work IRL so I’m gonna actually order parts and build it. Today, I split the gray gears (with the tube) into two parts so I can actually assembly it, added countersinks to parts that need it, and fixed up some tolerances.

I don’t have too many new ideas for the V3, but hopefully after I build/test V2 I can notice some key problems. Here’s the general gist of I’m aiming to accomplish:

• Obviously, I need to actually lock in with elliptical gears for the V3. This is the biggest problem with the V2. Because of the sinusoidal motion, the output gear isn’t constant speed (it oscillates slightly too).
• The whole extra gear for the CAM is super annoying, so I’m gonna keep it coaxial to the input/output shaft (running three things coaxial) and gear it from the tubes instead of a separate thing. I need a huge geometry change for this which is why I’m saving it for a V3.
• I want to figure out a better way to do the dog clutch system. I’m hoping there’s a smarter way which doesn’t rely on meshing/unmeshing but so far I couldn’t think of anything.

I’m really happy with where this has come, and I can’t wait to start assembling this.
