The WP pulley I used for my application is shown in Post #155 at 2 3/4" deep. Sometimes you have to improvise with washers or spacers to get the desired result for pulley alignment.
There are SO many combinations...that's why I called this a Rubik's Cube project :eek: Lots of work to figure out...
I think you're on the right track with the larger crank pulley to overdrive your WP. :thumbsup:
