Help please !! I have been searching the net for about an hour plus looking for a supplier of multi-rib, multi channel, or multi groove (whatever you call them) drive pulleys....am building a grinder and need a multi rib pulley.....I found all kinds of pulleys that have one to five v's for different speeds driven by a a v-belt but I need a pulley that will take a belt that has 5 ribs in it...one belt working on one pulley.....not a pulley with multiple v-options for different speeds.....I am so frustrated I can't even explain my dilemma in clear words :grumpy:
