simple option: take a string, wrap it around the tube, cut off extra, measure the string. Divide by 3, use a ruler to mark the 3 spots on the string, wrap back around tube, and transfer the dots to the tube. DRILL!
Accurate option: find circumference of tube. (you can find this by measuring the diameter of the tube, multiply that by PI) divide by 3, mark a starting point, drill holes offset by your length.
