Use the factory supplied speed wrench on the Classic. Have some ⅛" roll pin on hand to replace the turning handle keeper when it finally shears off. Got a ⅜" spinner wrench at Harbor Freight and a swivel ¾" shallow socket. I then use the Hensley supplied wrench to fine tune the left arms.
Tried the drill idea, but it's something else to keep charged. The battery tends to be low when I need to use it.....
