real cool! would you ever sell a batch of those?

Wow, those look incredible. Congratulations man. I don’t have any kids myself but if those showed up on my doorstep after I designed them start to finish I’d feel like I did!

Hmmm… No. Those ‘kids’ won’t wake up throughout the night and refuse to eat their dinner.

Sorry bro. Not all of us are fortunate

That was meant to be jovial.

Sorry if it wasn’t!

Maybe someday! I intended this as a one-and-done deal, and I’ll probably make different yo-yos in the future rather than re-tread this design. I just made a post about my “company” here: Mk. 1 Yoyos

Thanks for the feedback on the engraving :wink:

Haha. My kids are mostly over the middle-of-the-night wake ups these days.

For fun, here are almost all of the practice designs I made while I was learning Yo-yo CAD.

Many of these are jokes or practice clones of existing yo-yos so I could try to figure out how their design affected the moment of inertia. None of them except the Diffraction (bottom row 2nd from left) has seen the light of day and I haven’t been hired by any chapstick companies to make yo-yo designs.

Hey, I just downloaded Fusion 360, and I was wondering if you would tell me your design process because I don’t understand the videos on designing a yoyo in fusion 360 at all.

V14 looks like a wilder Edge Beyond lol

I’ll post more later, but do all your work in 2d sketch mode and use the revolve tool to see what it will look like and check the weight for you whatever aluminum alloy you choose.

Start out with a bunch of practice designs, try copying yoyos you like to see how their design elements come into play.

Is there anywhere that has just the guts already made in a 2d sketch, so that I don’t have to draw all of them? how did you start making each of those designs? because I saw that they look functional and I was wondering if you had to draw the tiny response area and shafts for each of them?

Here’s a downloadable Fusion360 file for the guts: https://a360.co/2Qjf2Qz

And here’s what it should look like in the editor:

Right-click on any of the lines and “Edit Sketch” before you make changes, then “Finish Sketch” when you’re done.

I’d recommend watching the series of videos by Zach Lerner to find out where these measurements come from.

Thank you so much, that was a HUGE help. And I have watched every video in that series at least twice.

Hey Mark, I think that sketch of the guts doesn’t really have a gap? And the width+depth of the bearing air groove and the response are the same? I haven’t done nearly as much designing as you have so you’re more of an expert than me, but thats just what I’m seeing, and I want to make sure we don’t accidentally mis-teach any newbies :joy:

These are the same guts I used for the diffraction, which has a 4.66mm gap.

Here’s a sketch showing where the bearing fits (magenta), and the axle (black) and pads (green)

What depth are you using on the response groove?

1.2mm off the top of my head. FPM told me the size to use for their in-house response pads.

Some recent designs. Just spending lots of time practicing things.

This one is an oversized (60mm x 47mm) bimetal with extreme rim-weight while totaling only 64.9g. Came about by the idea of “one throw” routines and what a yoyo that is designed specifically for them might look like.

This is an undersized (52.6mm x 40mm) outer-ring bimetal where I was experimenting with D-sized bearings. 63.26g. Haven’t messed with the pads or gap yet, need to do some research on those.

And this is me getting jealous of the Edge Monster. 60mm wide. Only 64g.

those bimetals look clean

also, your jealousy creation of the monster looks like the definition of the hourglass shape. call it the monsters nemesis or something lmao

Thanks! One of the small touches I added for rendering was creating tiny fillets in the area where the two materials meet, which is more real-to-life and also looks better in the software.

Oh man, I could round it out and make it look like an actual hourglass.
