I have a tube, 6" long and 1.5" in OD. I need to drill 3 holes, each 120 degs. from the previous one. These holes are through the wall of the tube. 0.25" from the end of the tube. There is no problem drilling the set of holes on the first end of the tube as is mounted in my vertical rotary table (RT) and then drilled in the correct locations.
However, the problem occurs when I need to drill another set of 3 holes in the opposite end of the tube. These holes are to be in the same angular position as the first set of holes. How would I align the tube in the RT so that when the hole was drilled it would be in correct alignment with the matching hole on the other end of the tube? Once I get the first one lined-up, the rest will be easy. Getting the first one aligned is the problem. Appreciate any assistance or ideas. Thanks.
