Hardware Questions

[Oblarg]

I've been poking around various hardware suppliers, and haven't been able to find a couple of things that my team will likely need for the offseason. I was wondering if anyone around here knows where I might be able to obtain the following:

1) Hex shafts which are turned down to fit into circular bearings on their ends. AndyMark sells a couple of these for use in their gearboxes, but they're made of steel and they're too short - does anyone know if any supplier sells these in either 6061 or 7075, or would we need to just buy a hex shaft and lathe it ourselves?

2) 3/8'' hex-bore 5mm-pitch HTD belt pulleys.

The idea here is that we're designing something in which we'd like to keep as many parts off-the-shelf as possible, so lathing our own parts, or broaching our own hex bores, is unattractive.
