Well I finally found a roller blade wheel to modify into a chain tensioner pully.I took it to work and had our machinist put it in his lathe and cut a groove in it.WOW what a difference.it runs smoother and allot quieter.
JE - nice tensioner! For a long time, my own tensioner has been the bain of my existence, but since I got a new frame (Greenline Qurve), it's worked out perfect. The Qurve has a more oval-shaped frame, and the tensioner fits perfectly with no chance at all of slipping. I'm glad you got yours worked out and your ride is now much smoother and quieter! 8)
Many recumbent homebuilders use the modified RB wheels, but if installed on the drive side of the chain they don't last as long. Some of the better ones i've seen use 11 to 15 tooth single speed sprockets, but installing caged ball bearings in one is a little more labor intensive than simply cutting a grove in the RB units.
