I'm pretty sure what those people did were just use the granny ring and grind down the larger tabs. Typically a granny ring is 22 or 24t but you could prolly track down a 25 or 26t.

I'm curious how they attached the sprocket to the crank itself. Does anybody have a spare Shimano crank and BMX sprocket kickin' around? Do the 4x64 BCD granny holes line up with those on the sprocket?
i think bikeit's point was that it isn't a bmx sprocket you are seeing in those photos. It's a 4-bolt XC granny bolted to the standard 4bolt granny studs in the crank arm.

the xtr thread was mine that i did and that was with the older xtr cranks both those picks are just granie gears on the cranks with the outer ring tabs cut off should work fine with a single speed set up, but there is no way to put a bmx ring on the new hollowtwchs they are a pressed on spinder that will not come off without being able to go back on.
A guy on the Eastern26 team a year or so ago had a sprocket on an XT crankset... thought I had a photo somewhere but can't find it.
Keep in mind, a few years back, when it was common to have a bolt-on grind guard on your bmx sprocket, some of them had a commonly used BCD that existed in MTB, like 104X4, or the smaller granny pattern (forgot the dimensions off hand)...
Then, with the cranks, they are simply ground down to only have the granny mounts, appearing to have almost no "spider" area...
