Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
Why am I not suprised to read yet another topic about failed S threads. Change your mesh to standard threads and don't look back.
Guess you missed the part about the last mesh that busted was Roller mesh (128n).To everyone else trying to be helpful,
Just thought I would add that we use only S mesh and only had popping problems with 310s when we first made the switch because we attempted to push the envelope with our tensions. After we learned that lesson we have had no problems and would much rather the S mesh over the standard mesh from our local supplier that we were previously using.
I still want to emphasize that there's something to the roller mesh that made it tough as nails compared to good quality mesh at the same thread diameter and tpi. And I guess there better be for the price they charge for that stuff!
