Title: My first finished project on my new lathe
Post by: YoDoug on April 26, 2010, 12:31:31 AM

I just finished my first project on my lathe that was just finished last weekend. I was worried that it might vibe too much because I had trouble holding runout to the same tolerance as I do on the Haas lathes I made them in the past, but it plays pretty well and only minimal vibe.

Nice yo-yo. Looks like it is a single piece...?? Could you explain then please how you made the ID bore with the conic rod in the middle? Custom ground tools?

Thanks for showing.

Yodoug, you rock.  Cool first project.  I'd like to know how you made that too;)

That is indeed pretty cool. I've never seen an aluminum yo-yo before. Thanks for sharing. The one under your name looks to be anodized with a splash pattern. Is this what your going to do?

Ok, here goes. My son got me into yo-yos and being a machinist I wanted to make an aluminum yo-yo of my own. As it turns out they are considered pretty good playing yo-yos by many people so it has turned into a side business for me. I sell about 800-1000 a year through different online stores in 6 different countries. They retail around $100 dollars each. I sponsor a few kids around the country that compete in contests and such. Here is a video that one of them made using one of my older models. http://vimeo.com/3736468

As for the machining, the yo-yo is actually 2 halves with a bearing in between and an axle holding it together. All the tools are standard carbide tools from Iscar or Kennemetal. It takes 6 tools to make each half. I use Mastercam to program and Solidworks to design. I just make the prototypes myself and I source the production to local machine shops and anodizers. Here is a section view of the assembly. I'll try to post some screenshots of the toolpaths in Mastercam later when I have more time.

That's equally as impressive.

Very cool!

A ball bearing yo yo has been on my "todo" list for a long time.  If I ever finish my CNC lathe, it'll be one of the early projects for sure.  In fact, my early Rhino drawing is the logo for my CNCCookbook page on Facebook:

PS  Those kids in the yoyo videos are crazy!  Shows what you can do if you lay off the video games though.
