This is a badge bit (BB) that is part of the 
PEP curriculum. Completing this BB is part of getting the iron badge in 
round wood woodworking. 
 
 This BB is for making a wooden trough out of a log.
 
 A dug-out trough made in a similar manner to a dugout canoe is made from a single whole or split log. It can be flat bottomed or raised off the ground on pegs to prevent rot.

 Dough bowls are made with similar methods. Since the previous video didn't show how to refine the interior, here's more.
