RE: need manual rack help
i am also contemplating doing the same thing as you and my wp is also underdriven. i have seen pics of people running the belt like your thinking with that little bit of contact on the wp pulley, im curious as to how well that would work though, i think i might perform the belt tensioner reversal trick and run it like that, will put alot more belt around the wp. the reversal trick is taking the tensioner apart and reversing the spring so the tension goes the other way, so its pushing up instead of down. if you search you should find a website that details it a little better, i did it once and its easier than you might think.
