Titanium hubs?

my brother is a machinist, working with titanium and using a variety of machines. I know nothing about titanium, machining metal or hubs. or stems or seatposts or whatever, really...

however, i asked him if he thought he could machine the body of a hub and he thought it would be fairly easy (they have seriously clever machines eg 5-axle programmable machines and he makes stuff with much higher (lower?) tolerances than would be necessary)

it would be cool. does anyone know anything much about this? why it could not be done? presumably bearings and skewers could be fitted if he made it right....

thanks

I think the main reason is that it would be heavier than aluminium when using the same
dimensions.

aha. really? i didn't know that. the results of my cursory google search weren't very helpful.

i don't think he can do aluminium. haha

here is a list of the density of different materials

but you should still do it and get some really crazy design made.

yeah, i'll have a set, if you're taking orders

well, maybe he could do aluminium, i guess it would be cheaper as well. i was thinking something like sherriff stars, but I am probably too heavy and would break them :S

the possibilities are endless...
