Diagram of the chime, chiv and croze
In this post we are going to look at cutting the chime. The chime is the bevelled edge at the top and bottom of the barrel cut with a cooper’s Adze. The top of the chime is leveled off with a special Plane known as a Cooper’s Sun Plane. Next the chiv (also called a howel in some areas) is smoothed in preparation of cutting the groove known as the croze.
Cooper's Sun Plane
The croze will hold the heads of the cask. It is cut with a Croze Plane. The head is formed by straight pieces of wood held tightly together by dowels. After assembly, the head is planed smooth and cut into a circle. Using his Drawing Knife, the cooper rounds the edges of the head to fit tightly into the croze. The inside of the barrel is then cleaned and the edges of the joints are levelled using a stoup plane.

The outside of the barrel is scraped clean and smooth. The temporary iron rings at the top and bottom of the cask are removed and the heads are fitted tightly into the croze with split reeds in the croze to prevent leakage. Permanent iron hoops are placed at the top and bottom of the barrel to lock the head into place. The temporary iron hoops on the body are also replaced with permanent iron hoops. Once the hoops are in place, the bung and tap holes are drilled and the cask is complete!
While this is a more modern video, and he’s actually refurbishing a barrel, you can see some of the tools used to cut in the head.
Assembling the Staves
In my last post on coopering, we left off with the shaping of the staves. We are now at the assembly stage. The staves are assembled into a cone shape inside an iron hoop.
They are placed over a cresset which is a rickety looking structure used to hold a small fire.
The fire warms up the wood to make it more pliable for bending. Black Creek has a steam oven designed to steam large barrels with thick staves. The staves would be moistened before being put over the oven. Once warmed, the splayed staves are drawn together by driving on successively smaller hoops known as truss hoops.
The hoops are driven on with a hammer driver and hoop driver. Riveted iron hoops, usually six for beer casks, are driven on, and the barrel goes over the steam oven one more time to encourage the wood to retain the barrel shape.
Next post – cutting the chime, chiv and croze!
Scotch Driver - These tools are grooved to prevent them from slipping off the hoop as they are struck with a hammer to drive the hoop over the staves.

Lemon Balm (Melissa officinalis)
Back by popular demand! Ed’s Lemon Balm Pale Ale was so well received, he’s brewing another batch. This crisp refreshing pale ale, has a hint of mint flavour and lemon aroma courtesy of the herb, Lemon Balm. For those unfamiliar with lemon balm, it’s a bushy herb related to mint that is easily recognizable by the strong lemon smell given off by it’s crushed leaves. In the past Lemon Balm was considered a healing and soothing plant, and especially effective in relieving pain due to indigestion. Lemon balm was also used to impart a lemony taste and smell to many beverages and foods. Ed will be brewing tomorrow and the Lemon Balm Pale Ale version 2.0 will be ready for sampling and sale beginning August 27th, 2010 only at Black Creek Historic Brewery located in the heart of Black Creek Pioneer Village in Toronto, Ontario, and available again only for a very limited time (until the barrel is empty!)
