Have you considered how those chamfers will be machined?

What size are the radii on your spokes where they meet the rim? They look like they might be awfully small.

Those do look a bit small, we just barely got by with a 0.25" endmill. Looks cool though!

This is one of the largest stress-riser locations in wheels, big radii will help a lot here.

Exactly. Cutting those chamfers serves no practical purpose (as far as I can tell), but will require a different tool and more time to cut. In fact, cutting them up where the spokes meet the rim the way you have might be difficult.

Yeah that's what I was getting at. It's virtually impossible to do that without gouging the wall of the rim.

If you had the time and money you could make the wheel a two piece assembly. Machine the rim and machine the spokes and use hardware to screw the parts together to make the final wheel. That would be a way to use two dissimilar materials to get a real light wheel or make a wider wheel but retaining the hub design year to year.

I may not have a lot of experience with wheels (as I've never experienced a build season), I agree with Tom Line. It just looks too complicated to build. It may look cool, but remember- looks aren't everything.

If you realllyyyyyy wanted to make it, you could 3D print one then make a mold of it and cast a set of them.
