Our only concern is that pulley being round/grinded down by the chain. I'll post some pictures of it after our next meeting.
Yeah, I thought about that when designing our tensioners, but eventually decided against it. Unlike idlers, it doesn't supply much resistances to the chain sliding sideways as well as a personal distaste for working with high powered springs. Eventually I had to ditch the design because we needed four tensioners. (Can anybody guess what we're doing? Hint: not omni) shortly therafter came the "block of HDPE" method... threw that one out due to bad experiances last year and an irritating mentor. Then came springloaded U-bolts which ended up mounted statically (although still adjustable) due to a lack of springs and length of the U-bolts. (Originally I planned to use the nice aluminum jobbies from McMaster, but they we're to wide, had to improvise)
