Exam 29: Bending Wood

Lamination bending, hot-water bending, and steam bending all require ____.

During kerfing, solid wood is more susceptible to fracturing across the grain.

A remaining wood depth of less than ____ inch should never be left at the bottom of the kerf.

When bending stock into round or elliptical shapes, solid forms are often used.

The lignin is made soft and pliable through ____, which allows the cellulose fibers bound together by the lignin to slide past one another.

The amount of curve that can be achieved through kerf bending depends on the depth and spacing of the kerfs.

In coopering, ____ work created containers for holding dry goods.

In steam bending, the rule of thumb for steaming time is one hour per half-inch of wood thickness.

The disadvantage to bent lamination is that it is very weak over any degree of arc.

Plain bending is limited to fairly thick pieces of stock.

The steam generated for steam bending is at ____ degrees.

When working with hot water or steam, it is important to have the forms close to the heating source.

____ bends are made by bending thin layers of stock that have been coated with glue around a form.

Wider staves mean more pieces will be required to complete the curve, but it will also result in a greater thickness.

If tight curves are to be made using steam-bent lumber, a bending ____ should be used.

In coopering, ____ work was the making of containers for powdery material.

Both solid wood and plywood can be kerfed for bending.

In coopering, the beveled pieces are called ____.

The major advantage of kerfing is that is strengthens the board.

One way to bend wood is ____ bending, where you take the piece by hand and hold it in place with fasteners, adhesives, trim, or a combination of these.
