Sorry if this is the wrong group. I'm wondering about how the use of a
crow's foot should be calculated for a desired torque setting using a
torquing screwdriver?

I fully understand how to calculate the torque setting for a torque wrench when using an adapter, but doing the same for a torque screwdriver is a bit more challenging.

For instance, the maintenance manual for an aircraft engine states a torque value of 12 in.lb on a fuel injector B-nut that is difficult to reach, requiring the use of a crow's foot that has a 1 in. reach. My smallest torque wrench has a range of 15-100 in.lb. so it can't be used, but my torque screwdriver is 5-36 in.lb.

How do I calculate the tool torque value that will let me deliver 12 in.lb. using a 1 in crow's foot with a torquing screwdriver, please?
