Here's a link to
Park Tool torque specs page. Notice the
51-57 lb*ft of torque needed? That's
extremely high and about the only thing I ever use that needs more than that are automotive headgasket bolts. And I need a 2-foot torque-wrench to achieve the 60-66 lb*ft needed for those. So tiny 10" bottom-bracket wrenches need like
68-lbs of force on the handle to get the necessary torque. On Italian BBs, I've used Sheldon's bolt-and-nut clamping method, but used to
tighten the fixed-cup, and even then, I still needed a 2-foot torque-wrench to get the requisite torque.
