Can you point me to the Naxo jpg you found?
Regarding, using the plates to check conflicts with existing holes, I've been simply using a grease pencil in them to mark the ski. Using a punch has less slop and I'm wondering if dipping the tip in some kind of marking fluid would work better. Any ideas on non-permanent marking medium?
