The part does need to be once piece, this is because the spokes of the bike wheel would be mounted pulling on those smaller holes to keep the wheel tensioned and true.
I wen to my local bike shop the other day to ask him about lacing the wheel, and what he thought about doing this overall (i will agree that bike shop guys really know their stuff). He hadn't seen someone do this before, and wasn't really sure what another reliable way would be to do it.
I will have to check out the MFGquote place. What do you mean by "but you have to look at the manufacturer very closely!"?
emachine shop is nice, i could say it was the first time i used CAD hehe. I've heard that they're pretty expensive, and i would like to have my part before the amount of time it would take for them to make it :"/
this hub will be mounting to two of these
guys i don't want to have this wheel cantilevered over the shaft tooo much (this is the reason for the deep holes on each side of the hub.
