With help from many of the members of the Teton Gravity Research message boards, Jon maintains a set of paper templates for mounting bindings to skis. These are also a great resource for checking for hole conflicts on multiple mounts. All of the templates print on 8.5x11 paper, but be sure to check the print with a ruler and adjust the print scaling percentage. Please also be aware that these templates may be updated at any time, so please be sure that you are using the revision linked here (suffix R2 denotes revision 2).
If you want to discuss the templates, or want to help create templates for bindings not listed here, please visit the active discussion here.
