-- For those Hegner users with the knurled "quick-clamp" knob option : One way to add "comfort" to using it for long stretches is to slip a pair of snug fitting model car (r/c toy car?) miniature rubber tires over the knurling, in a side-by-side setup...A tight fitting size is best, possibly even requiring warming the tires first in hot water for a tight stretch-on install...After many hours of use, my outside tire eventually "wore off" - via the knurling eventually "rasping" the inner mounting surface of the tire : a quickie slip on of a snug fitting o-ring (plumbing type) alongside the remaining tire has kept me scrolling along, without "meat tenderizing" my fingers... ~Pitts~
