Hey Don,
for the Machinist, Woodworker X-35 and X-50, and Journeyman models, which have Y-35 rails (both Standard and Elite Series), the cutting area location is here (assuming you have Z-16 assembly and 65 mm router mount, with 80 mm spindle mount, it’s 15 mm more towards front (does not apply to Z-20/Elite 65 mm and 80 mm mounts!)), but on Foreman which has Y-50 rails and Z-20 assembly I don’t know. Someone still needs to provide this measurement to the forum (one for 65 mm, one for 80 mm mount).
