It surprises me every time I have a session with it. Such a chill yoyo. It even hits that ASMR button for me; when I do an extra snappy bind, the noise it makes is this delightfully hollow-crispy snap!
Good times. Gooood times

Love most of them.
Some don’t work.
Some are too light on the string.
Some turn to quick on the string.
But I really appriciate your works dude.

I retract my statement that response bumps kill the feel of a yoyo. That isn’t necessarily true. It’s much more about the overall design.
I do feel the response bumps in your design are a bit too aggressive, though.

Yeah, no doubt. Thanks for all the feedback, it’s helping me to refine my design thoughts.

does anyone know how bi-metals are made, in terms of how the metals are bonded together?

Press fit
Edit: my guess would be .005 over for the rings would be ideal

Hey Mark! Do these guts work for size C bearings?

Just curious, what CAD software does everyone use that is best for yo-yo design. I’m looking for something free and easy to use for someone just wanting to try it out. Thanks!

Thanks! Got confused because the file is named “Yoyo D Bearing” 
One more thing: given that I am a total noob and just now started going down this rabbit hole, if I were to adapt these guts to a 10mm axle, I just need to increase the hole to the desired 4.92mm (as per Zach’s video), right?

I may have uploaded the wrong one by accident - here’s one for C: Fusion
I’m using Fusion 360. It has plenty of online tutorials to get you through the basics - drawing lines & circular arcs, rotating around an axis to create a 3d body, applying materials and appearances, mirroring bodies, and rendering.

A group of portland throwers designed their own yoyo recently and had a small run made for their yoyo club to try out:
Love seeing this sort of thing pop up!
