I made an extra long wrench socket for field repairs of a heavy duty pivoting contraption by cutting a normal 1-1/4” socket in half and welding the wrench and handle sections to either end of a 6” length of steel pipe. The pipe had a smaller outside diameter than the socket halves, but big enough for the threaded rod.

Imagine the hijinks the first time I put that through an airport scanner. Good thing it was 2000 and not 2002.
