Re: How do i make this part??

In looking closely at the drawings for the hub, quite frankly it is not all that hard to make. Time consuming, perhaps, but not a technical challenge. It is important that you find someone with machining epxerience, since selection of tools and turning speeds are important.

You do need to get the material first, and you will need material that is at least 2 inches longer than the workpiece - maybe 5 inches for each hub. You first cut the outside profile and then the deep bore on the one side. Mark the rim every 20 degrees for the small holes now, too.

Flip the piece and grip it inside the deep bore, and make the shallow bore. Drill the 4 holes, and then the 18 holes (make a jig to do that, as they suggest, using the 4 holes to locate the jig. That way, you only have to be careful with one piece (the jig) and all four edges (2 hubs) will turn out identical with little extra effort.

I would allow for 3 hours for each one, but I'm experienced, so allow twice that for the first one. Also remember that tolerances are not that critical, so long as both are the same. +/- 0.010 is more than enough.
