The zinc coating that is on the shafts now is marred very easily by collets being screwed onto the shaft. A harder coating would be very much appreciated, and maybe a coating with lower friction. Maybe TiNi or some other coating.
oops, that should say TiN (titanium nitride Titanium nitride - Wikipedia )
Thank you for the feedback. We will investigate whether it is feasible and cost effective to improve the coating on the VEX Shafts.
