Claims1
A first apparatus comprising means for centering a stepped device not having external threads or pawls in an end of a pipe, and means for generating a first laser beam from said device along a longitudinal axis of said pipe, the first apparatus further comprising means for rotating a first pattern generated by said first laser beam;
- the first apparatus further comprising a second apparatus comprising means for centering a stepped device not having external threads or pawls in an end of a pipe;
- and means for generating a second laser beam from said device along a longitudinal axis of said pipe, the second apparatus further comprising means for rotating a second pattern generated by said second laser bean;
- the first apparatus further comprising:
- means for using said first apparatus in a first pipe and projecting a first pattern in a direction;
- means for using said second apparatus in a second pipe and projecting a second pattern in said direction;
- and
- means for rotating each of said first apparatus and said second apparatus to align a portion of said first pattern from said first apparatus and to align a portion of said second pattern from said second apparatus with each other forming a substantially straight co-linear intersection of said first pattern and said second pattern.
