How To Size Your DRO Scales:
Measure your total Cross Slide Travel, and Total Carriage Travels
from end to end. Choose a scale set that is at least 1 inch longer than
your travels to make it easy for you. Only order the closest size up to
your travels, do not order too large.
Example: You have a 12x36 lathe, with 6" Cross Slide Travels, and 33"
Carriage Travels. You would order the PM-8.5x36
