Actually I think so! Here’s a couple things I think should be edited:
^ This is the best post. Ever. But seriously, that yoyo looks like something Death would own to torture people’s souls.
Not be the one but that design is kind of unrealistic and isn’t a design that is likely to work. I’d say start a new design and work with something that can actually be machined and wouldn’t kill your hands.
It’d be a challenge, but it looks much better! And beautiful! And honestly I don’t think it would destroy your hand. You gotta remember this is the yoyo half, cut in half. In a full circle the face your hand touches would be smooth. And with the right depth, you could probably get a thumb grind. And it doesn’t look as fragile as before.
He just needs ro dull the outer rim a little
Hello everyone,
This is a really fun thread and I love to see everyone’s designs. I do agree that if you are looking for design reviews and advice it would be best to make a new thread. You can PM me if you want me to look at it. I am happy to tell you if I can machine it or not. For what it is worth, I am not going to be machining the design by Yoyo Kangaroo anytime soon. While it looks cool, it is not really within my reach and my opinion is that many machine shops wouldn’t quote it and those that would will ask for a lot of money. The advice to thicken it up and remove some of the sharp corners is spot on. The later designs are more likely to be able to machine, but I still will focus on the simpler designs.
Some people have pointed out that unless you have CAD you are out of luck. That is not true at all. While it is much easier for me to work from a CAD file, I can help you make one. However, please don’t post them in this thread. I want to keep this thread about my experiences machining and not designing 10 peoples yoyos. Some helpful advice for hand sketches. 2D and 3D look very different. So try to think what the 3D shape will look like. Use Graph paper and draw you lines as accurately as you can. The sketch can be very big, use up the entire page to show the cross section and use the grid to keep things in scale. I will be importing the sketch into Solidworks and tracing your lines. Finally, use a scanner to get a high quality, in focus image. Cell phone pictures of a piece of paper are not fun to work with.
With that out of the way, back to the real topic. I just spent $70 for some supplies. Hopefully, down the road I can earn it back. 
Here is what I ordered:
12" length of 2.5" diameter 6061 aluminum bar stock. I think it will take about 3" per yoyo.
TIN-Coated HSS Hand Tap 3 Piece Set (Taper, Plug, & Bottoming), 8-32
Miniature Double-End HSS Two-Flute End Mill 5/64" Mill Dia, 3/16" Shank Dia, 1/8" L of Cut
Type 316 SS Cup Point Set Screw 8-32 Thread, 1/2" Long, packs of 50
The tap set should let me tap the holes deeper and get more of the axles engaged. This is really important for when I flip the hub over and use the axle hole to hold it in place while I machine it. The miniature end mill will be used to machine the bearing seat and response groove. The set screws will let me make quite a few yoyos as long as I design them to use the same axle.
Anyone know about the material choice for axles? These are stainless steel, but I think both of the axles I have are black alloy steel. Is stainless steel a common material for the axle?
Anyway, everything should arrive in a couple days and be ready for more tests this coming weekend.

Stainless steel is avery common axle material.
It works great
Awesome of you to do this! I won’t use any of your services for a couple reasons… I’m broke and know nothing about designing yo-yos! Haha. My first one should be coming in the mail this week. Nice seeing a good sense of community though and the cool work you’ve done already!
I think everybody is missing the point here… Pics of this Clouds Buster Sword. Did you make materia slots? 
Also, Can’t wait to see your metal yoyos! Did any of my files I sent you help you out?
Would you be interested in trying to machine a H-Shaped Delrin?
Hi Guys,
I got my tools and the raw aluminum in the mail today. It is sitting on my desk and dreaming about one day becoming a yoyo. lol Here are some pictures.

Also, I took a look at the One Drop project gcode. It is really cool that they published that. But they have tool definitions and don’t tell you which tool they used, or if they have any tool offsets. I can kinda guess, but the gcode that they publish is definitely not enough to just plug it into a machine and spit out yoyos. CNC machining is a little more complicated than that. lol
Still there is a lot of information that I can learn from looking this code over. Has anyone else ever used this code to make a One Drop? Just curious.
Sure I would give it a shot if you pay for the Delrin and have a CAD model. The cost of materials is the ‘mostly free’ part. It just would be silly for my to be machining yoyos for other people and paying for everything out of my pocket. I would quickly go broke. The other reason for this is it keeps people who are not serious about it from asking for yoyos.
Josh
I really wish I knew more about yoyos and cnc type stuff
Once again, pics of Cloud’s Buster Sword.
I will take a few pictures and make a blog post about the buster sword. Once I move into my new house I plan on mounting it on the wall. The cnc machinng of the yoyo is helping to build the skills needed to cnc mill the hilt for the mastersword. So hopefully I can finish that project by the end of the year and show some photos of that too.

How many mm are the axles?
I am workin on something. Are those even axles? I have spare 8mm axles.
Awesome man!!
Also - remember that first design I showed you? It is being machined by Foxland Precision this week Making 4 protos - hopefully 3 in 6061 and 1 in 7075, not sure yet.
Can’t wait to see what you come up with in the future for throws! I want to partake in playing whatever you make as well!
I always wondered what the raw aluminum looked like before machined
Guess I gotta learn hot to design on a CAD, and buy Delrin as well. This might take a while.
I can do some CAD work for you
