VEX Shaft Collar Specs - Help!

I bought several of the Radio Shack V.5 kits, and noticed there were NO shaft collars in any of them! Running to the hardware store, I find they are both VERY expensive (several dollars each!), AND the standard sizes they stock don't QUITE fit the 1/8" square shafts.

SO... I need to fab some ASAP *today* on a lathe, for an event starting TOMORROW! (I have the raw bar stock for this now...)

Could someone please quickly measure a standard collar, and post the specs for it?
I NEED: ... ID, OD, Width, Setscrew size & type (thread, length)...


The setscrew isn't vital (the first 3 numbers are more important to me), but it would be NICE to only require the same basic Allen Wrench as the cap head screws and have them mix with others, so I'm ASSUMING it's either a 10-24 or 10-32 Allen Head setscrew.

Thanks!

- Keith
