I got a 8" Delta 37-315 jointer with a 3 Hp (Baldor TEFC) motor but only a single 'A' belt to the curtterhead. I wonder whether it should have more than one belt given the 3 HP motor and the 6" and 2 1/4" pulleys. Seller is a boatbuilder who upgraded it to 3hp to take 'hefty' cuts off boat lumber. I found a Baldor manual on power transmission but frankly, got lost in the morass of technical details. Would anyone know what the rule of thumb is in this case? Would I gain anything by two belts? Thanks in advance
