About how many shots do you think you're getting on those nuts? That's
what, the 80 lb draw model?
Delrin or UHMW are both tough but low-friction materials. The size and
shape of the tickler's contact surface would make a huge difference
too. I mean if they started with a small rod stock for the tickler, not
only is the holding psi many times greater than a wider section could
potentially be but also as it moves away towards the instant of release
the rod cross section thins out very small , psi increases and chips off
a middle of the edge of the nut each time as it goes past.
