What I found in the specs is that I could use a wider belt. For example a 12mm wide belt can transmit twice the torque of a 6mm wide belt. But then I find that are side forces that force the belt in a direction parallel to the pulley axis and the side force goes up as the belt gets wider. Worse is that the larger GT2 pulleys lack flanges. The belt could walk of the pulley unless I resorted to high belt tension and pulley flanges. The 9mm wide, 3 mm pitch belt seems like it should work -- Chris Albertson Redondo Beach, California ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
