the pulleys are staggered. The middle one is 15mm while the ones on the cim are 9mm so they dont overlap. I may be misunderstanding your comment?

whoops. my ball shifter weighed over 2lbs actual weight is 1.85lbs.

funny thing. The one time me and Chak had to remove a roll pin, We spent a good ten minutes hammering it, then broke a drill bit. I ended up going in with a dremel and cutting apart a steel coupler instead of taking out the pin. guess it left a bad taste in my mouth.

I'll take a look at some sdpsi pulleys. should be easy enough to increase the ratio from there. maybe shave off a tiny bit of weight as well.
