Hey Joker,
I love it when a plan comes together!
I have a similar problem with my 13T counter rubbing my case's... Camm 22 had his countersprocket counter sunk and worked like a charm...
I'll look for his post and piccy. would this sound feasable? That's alot of torque pulling the chain off-center.
Chain is not cheap, and sprockets would also suffer.
Best of luck on the build & keep us up to date.. This sounds like a Very Cool Project.. I have only seen piccy's of the ATK.
