How to size a lathe to get its’ travels for linear encoders?

Carriage Travel

First, position your carriage towards the headstock until it ‘bumps up’ against the headstock, make a mark on the bed just to the left of the apron; Reposition the carriage all the way to the tailstock end; Measure between the previously made red mark and the edge of the carriage apron, this distance represents your total carriage travel. As in the case with most scales, we recommend allowing ~ 1/2 inch clearance on either end of the scale to arrive at your total required scale travel.

Cross Slide Travel

Move the cross slide to the full most forward position, Make a mark on the cross slide, next, make a corresponding mark on the saddle, opposite the mark on the cross slide, reposition the cross slide to the rear-most position; The distance between the marks represents the travel of your cross slide.
