Answer what post?

Ok, let me try to field this question.
I finally found your post with your drawing on another part of the forum.

Your drawing is to non-specific for us to properly answer your question. If you can add some measurements that would make it much easier.
The choice in metal doesn't look to be the best choice. I am assuming you will want the spoke area of your hub to be one piece and not two flanges welded on to the center hub? If so you will need to pick a much thicker wall or just a solid bar of aluminum. Someone else will have to speak on the choice of 6061 as for strength and durability.

If a solid bar is the choice, then you would use a lathe to cut the outside flanges, bore a center thru hole and then bore the bearing race area to size. Spoke holes would be done with a indexing head or rotary table and mill.

From the other post your grainer link has expired and it doesn't show a bearing, only that your session has timed out. Post the part number of the bearing or use a different link and we can have a crack at it.

here's grainger item #
1ZGD5
i'm attaching a picture of it.
i want to 'bore' a step in each side of the aluminum
tube for the bearing to sit in.
yes the flanges for spokes, sprocket and brake drum/disc
do slide over tube and get welded true.
this is a wide open design that can be adapted
to particular application.

I would think that the bearing would need to be a tapered roller type to absorb the loads in all directions. Thinking mainly about a car front wheel bearing set up. Two tapers facing each other to get maximum strength and the best true smooth rotation.
