stabbing board

noun

noun

A temporary platform erected in a derrick on which a derrickhand stands to run in casing.

The derrickman releases the "stabbing board", a pivoting plank like a diving board, then walks out to the very end and, wearing a safety harness called a "belly buster", leans out at a horrific angle to make sure the pipe is lined up straight.2005, Paul Carter, Don't Tell Mum I Work on the Rigs, Crows Nest, NSW: Allen and Unwin, page 68:
