Historical information

Before setting the barrel head, the cooper smooths the inside surface of some barrels with a stoup, compass or circle plane and an inside shave (or in shave plane). A stoup or compass plane has a convex sole in both directions to work within the doubly curved staves of a barrel. The cooper smooths the outside of the barrel with a downright, another large-handled shave, and a similar scraping tool to finish off called a buzz. The final step is to fit the head and drive on wooden or steel hoops.

Making the barrel has taken a number of planes similar but different from those of other trades, each perfectly adapted to a cooper’s work shaping curved surfaces. And if he has done his work well, the barrel will hold the exact amount of liquid and not leak.

Significance

A tool unique to the cooper used to smooth out the inside of a barrel that has been in use since the making of wooden barrels and buckets for hundreds of years without much change to the design or how the tool is used.
