We have Shimano splined BB cups. I have 3/8" drive (bar and pointer) torque wrench. I have a Shimano splined BB tool. I have a 15" adjustable wrench.
OK, so I can use a skewer to hold the BB tool in place while I tighten things with a big adjustable wrench and guesstimate the torque.
My question is how can I use the torque wrench without resorting to the somewhat dicey method of holding it in place in the shallow splines of the adjustable cup with one hand while I torque to 400 in-lbs+ with the other?
I torque the BB successfully by being careful. Still I feel I am just one careless moment away from damaging the cup splines.
I have searched for a 32 mm crow's-foot (32mm being the size of the hex faces of the BB tool). No joy. Park makes a 32 mm crowfoot but it is octal only not hex sided.
Is this how an LBS does it?
