I did it exactly as Ken described and everything worked fine until I tried to torque the lug nuts.
According to the instructions from Vintage Wheels 80 ft lbs of torque are required for 1/2" thread size wheel studs, but at about 70 ft lbs the allen wrench begun to round off the lugs




The lugs distorted so much the wheel wouldn't slip over them anymore.

I'm still trying to figure out what went wrong. The allen wrench end seemed a little loose in the lugs, is it really a metric size?

Also the material the lugs are made off seems very soft like mild steel, I wonder why they're not made of heat treated steel.

Does any of the other companies (Trigo, PS engineering etc) sell lugs made of stronger material? Are they interchangeable?
