1. An apparatus for drifting a plurality of cylindrical diameters, the apparatus comprising:
a first tubular with a first inner diameter and a first outer diameter;
a second tubular with a second inner diameter and a second outer diameter, wherein the second outer diameter is smaller than the first inner diameter;
a first fishing neck on the second tubular;
a first plurality of attachments that couples the first inner diameter of the first tubular and the second outer diameter of the second tubular, wherein the first plurality of attachments is removeable to allow the second tubular to translate along an axis relative to the first tubular;
a third tubular with a third inner diameter and a third outer diameter, wherein the third outer diameter is smaller than the second inner diameter; and
a second plurality of attachments that couples the second inner diameter of the second tubular and the third outer diameter of the third tubular, wherein the second plurality of attachments is removeable to allow the third tubular to translate along the axis relative to the second tubular.
