ok - made a page about it - quick and some pics are not the best, but oughta help if you wanna rip things apart - speak up if I've missed something, and maybe this can be a tech tip if it seems helpful -
find it here for now
not wishful thinkin Fred, you could take things apart far enough to reface the wheels, and clean it up at the same time - just go slow and careful!
edit: changed address to the 'bolt tech tips location
