chris in bc Posted September 29, 2013 Share Posted September 29, 2013 I own a very nice 633 loose ground coffee machine. I would love to convert this beast to a 637 dual grinder. Fresh ground coffee tastes WAY better! I know I need 2 grinders, 2 chutes, 2 bean hoppers-anything else? Also; 1) with oily beans I find these 637s just "pack out" with grindings in the bullet style grinders-any solutions? 2) can any person rebuild these grinders? 3) I can only vend 120z cups, does any person know of a kit that will allow these 637s to vend a larger cup?
