[Ansteorra-archery] speaking of crossobow repairs...

[Danny Miller]

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.
