Do you have a lathe or a mill?
He indicated earlier in the thread that itās a mill.
I have access to 4 manual metal lathes, 3 manual metal knee mills and a mini-lathe. I also have access to a cnc mill which is what I was machining those parts on it is a Tormach PCNC. I also have access to a whole much of other tools because of my job. I am lucky that my work encourages me to use the tools for my personal projects. The more I use them, the better I am at prototyping things for work. So it is a win-win situation.
I also have a cnc mini-mill which I am building, but have not made much progress since last year when I got access to the Tormach. No real point in spending time building the cnc mill, when I can just use the bigger better one. There are details of that machine on my blog.
I wish I had access to a cnc lathe. I have been kicking around some ideas of building one. Maybe I can crowd fund it or something like that. Right now I am just working on the 3d model and when the design is close to complete I will make a new thread to discuss it.
If people are interested in the tools and shop that I work in, I can take some photos and show you.

id love to see it. when i visited one drop the bar stock was what held the machined part in placeā¦
like go watch the summit documentary and see how they do it. its just in the one drop then look at the summit. the vid is right on the page
I have actually seen that documentary and it is really cool. They machine it differently from how I do it, but they still flip the hub over. They machine the cup of the hub first and as much of the catch zone as they can. But then they cut it off and the hub falls down into the bin. After that they flip it over and use an expanding chuck to hold the inside of the cup while they machine the bearing seat and response. That is still the hard part because you have to get it spinning true again. I wish I had access to those tools. But I am not complaining about the tools I have access to. It just means I will need to build a cnc lathe soon. 
On another note I got some packages in the mail. Yomagic mailed me four new powder coating colors and 17 yoyos. WOW. He wants 13 of them powder coated and some laser etched. I am gonna get a lot of practice powder coating. He sent me four for me to keep and now I have a growing collection. he also put in a counterweight which looks like a panda. lol. I have thinking about trying out some of the other styles. I am so glad that I created this thread, getting to meet everyone and get more excited about yoyos is really fun.
I also got two weird hours that need tumbled and one will get powder coated. As always here are some pictures.

Wow looks like a lot more than I thought haha! Welp the more to practice on haha That imitation gold looks amazing in that jar haha!
HEY! Those āweirdā hours are mine! 
Yep those are SlimJoeās. I wanted to thank you for the red and black yoyo too. Is that a modified Duncan? It plays nice and I like to go back to the narrower style sometimes to force myself to keep myself from getting lazy. I am gonna paint your yoyo first, since you mailed it to me. That way I can mail it back to you quicker as well.
I tumbled them already and they are pretty smooth. But I think I will toss them in the tumbler for a while longer to get them even nicer.
Josh
He gave you a modded freehand2 that was done by yoyospirit
I used that yoyo for a bit to smooth out my 1A. Itās a modified Duncan FH2. I think it was done by yoyospirit? Those spikes HURT haha.
And thanks! <3
EDIT : yomagic beat me to it.
I died.
Time for another update. If you want to read more or see more pictures you can see the whole thing on my blog here:

I mostly donāt want to retype everything. But here are the highlights.
I finished 4 more powder coatings today. I decided to try a new way to remove the annodized layer before powder coating them. Actually, I am not sure that you really need to remove the annodized layer, but that is another topic. I tried chemically stripping the annodized layer rather then mechanically striping it. When I was reading about this, I noticed that some people have really strong opinions about this topic and I am sorry if I start a forum fight. Personally I wanted to try both ways so I would have experience. Also, chemically stripping it would be useful if I start anodizing because that is one of the steps.
So here is what I did. I got my hands on some Greased Lightning. This is a caustic soda mixture and is used to clean things like the kitchen stove. Everywhere I read about doing this people made a huge deal about it being dangerous. Personally I donāt think it is, but it depends on what you mean by dangerous. It is true that you should not drink it, nor should you take a bath in it. But this is hardly going to eat the flesh off your hands if you touch it. (It will eventually do that if you leave it for a long time) That being said, children talk to your parents about this and everyone else take some basic precautions. Do it in a well ventilated area, and keep it out of your eyes and off your skin. Some rubber gloves work well, or just wash your hands if you get it on you.
Anyway, I soaked the part in the cleaner and after about 10-15 minutes it was down to bare metal. I tried agitating it a little ever so often to move the cleaner around and help the process. I also tried using it in an ultra-sonic cleaner at work. This just vibrates it and speeds up the process. It worked well, but didnāt get all the anodizing off. Some of the corners and in the bearing seat the annodizing was more stubborn. But it removed it well enough for what I wanted to do. But the results didnāt blow me away.
Then I cleaned the parts really well with soapy water. You donāt want to leave the caustic soda on them because it will create pits in the surface. Here is a picture.

Then I used the laser cutter to cut some rings of the high temperature tape I use to mask off parts. Here is a picture of it. I used that to cover up the bearing seat.

I weighed the hubs before and after powder coating. I wanted to have some hard numbers to see if I was putting the powder on evenly or not. If the hubs have different weights after powder coating, I know it is not good. If they are the same it is a good sign, but not proof that the powder is even. It is possible to have the same net weight, but all of be on one side or the other. But that is not really likely.
All the hubs were equal weight within 1/10 of a gram. My scale couldnāt measure anything smaller than that. After powder coating 2 of the yoyos had the exact same weight hubs, and the other two were within 1/10 of a gram. So I am pretty impress with how close they were. I wish I had a more precise scale, but not sure where I will get one.
Over all the yoyos came out great. I hope the owners like them as much as I do. I have another 9 yoyos to coat and I plan on weighing them all. Also, I am gonna try doing some without removing the annodizing as I have read that annodized aluminum is actually a very good surface for powder coating.
Here are some more pictures. The bearing seat and some of the response grooves are the original color of the yoyo. But my thought is that once you put the silicone and bearing in you wont be able to see that at all. I hope people are okay with that.

I look forward to your comments.
Josh
Looks fantastic. Thatās about my only comment. 
Amazing results!
DAT WRATH!!! Dude that looks amazing. Iām really digging it. That gold looks sick
Weight needs to be equally distributed. If the sides both gain a gram fine but if 75% of that gram is more to one side not so good.
You are absolutely correct. But I donāt have a way to measure the center of gravity easily. I stated that this doesnāt prove it is evenly balanced. But if one hub gains 1 gram, and the other gains 2 grams I am absolutely not putting the powder on evenly. Weighing them can prove it is bad, but not prove it is good. I was saying that weighing them did not prove they were bad, which is a good sign.
Balance is all that counts in the spin game. Weights a matter of preference.
But you want both hubs to weight the same amount too. If one side is heavier that isnāt good. Part of the deal I made for powder coating these was that the owners would write a review of how well it turns out. I will leave it up to them to say if there is any vibration or not. My goal with weighing them was as a way to gauge how evenly I put the powder on. It isnāt the whole story, but I am an engineer and I like to have as much data as possible. Also, several people asked how much powder coating would add to the weight. This data is gonna allow me to give them hard numbers instead of saying āit will be a little bit heavierā
Josh
Ahhh yes the ever popular āmy yoyo weighs a half gram more and plays totally differentā. :
