How do i make this part??

Oooh, that part makes me cringe when I think about actually milling/turning that part.

Does it have to be one solid piece? It would be a lot easier to make that part if it were two halves that bolt/weld together.

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.

Any shop with a good CNC Lathe can turn that out in no-time. The holes around the perimeter are also trivial on even an NC Mill. The trick is the tools you use to build it. You should be able to use Google to find a machine shop in your area that can quote the part (A really good shop will ask for the 3D files to make the part). Who knows - you might even find a new sponsor for your team this way!

Good luck!

I would agree that local is typically a better connection.

If that's not an option, what I meant by my word of caution is that not all shops have same quality or service. I didn't have any real problems with the 4 companies I worked with.

MFGquote will get you a good number of quotes (from around the world) in a day or two and they will have a huge range (just a guess $50 - $800) and you'll just need to look up the suppliers rating on the site. It's just like buying anything else online, sometimes the cheapest will only get you a bad product (and sometimes the most expensive will). Look at local or regional bids and to keep the cost reasonable correctly dimension your drawing with reasonable tolerances.
