This is my go-to belt calculator: https://sdp-si.com/eStore/CenterDistanceDesigner Desired center distance: 4.8750" 79 grooves - 4.8582" 80 grooves - 4.9591" 81 grooves - 5.0599" Actual screenshot sent to you as PM. -- MC Cason Eagle3D - Created by Matthias Weißer github.com/mcason/Eagle3D ------------------------------------------------------------------------------ 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
