Speaking for only myself not anyone else....
It's not actually that hard to fabricate wheel hubs.
I could understand the issue if a team was in dire need of basic shop tools.
I could understand the time might be more valuable if you could buy them.
Well you can't buy them fast enough - so why not try to make them?
Is it really more practical to gripe about it?
What's the worst that happens you fail to do it right, or would you rather, risk not getting it done?
I am actually way more surprised that someone hasn't risen to the challenge and started posting examples of making wheel hubs.
I suppose some people want to weed out their competitors like this.
