Maybe not so unique...



It's an idler pulley assembly with the bottom half sliced off and the 
business end welded to a plate.   The "roller" is a bare idler pulley 
bearing, sans pulley.   The rationale behind it is intriguing 
although the engineering isn't; that little pulley bearing is gonna 
be spinning at around 40,000 rpm if the car's engine gets revved up 
tight.   I'm wondering how long it's gonna last if it gets buzzed up 
like that often.



Still a handy idea.   Fabricate a 3" diameter drum of some sorts from 
the original pulley and lay it on the belt if you're gonna do this, 
better chance it's gonna stay together.   Or, go junkyarding for one 
of those cute little spring-loaded serpentine belt idler pulleys you 
see on almost everything.   Fabricate a mount/plate like this guy did 
and go on down the road.
