Good point about flares. Although the super tight spiral also decreases the useful range, so reprofiling would improve this thing a couple ways. Come to thing of it, specialty cams could in theory be constructed with a greater cam angle specifically for flaring placements, though no doubt theres an outside limit to that.
Someone should build a dual load cell test jig with a crack that has an adjustable taper to compare pull out force vs cam expansion force, like this:
Sure wish i had the money to build it.
