When measuring an adjustable reamer, I'm assuming you want to measure the outer most edge of the cutting blades for the correct sizing.
Any tips for setting up an adjustable reamer would be greatly appreciated.

Tim, adjustable reamers in my view are for emergency scenarios where a piece of machinery needs to be placed back in service immediately and the adjustable reamer allows for a bushing to be sized immediately, ...but not sized correctly. What you will find under a microscope is the chattering of the cutter blades make a sawtooth pattern into the bushing. The shaft is initially supported by the "teeth" or points in the bushing. As they quickly wear, the clearance becomes out of specification.
