Deck 29: Bending Wood

Question 1

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.

A) hand
B) combination
C) plain
D) kerf

Answer 1

C

Question 2

The steam generated for steam bending is at ____ degrees.

A) 198
B) 200
C) 210
D) 212

Answer 2

D

Question 3

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

A) Standard
B) Plain
C) Kerf
D) Laminated

Answer 3

D

Question 4

Both solid wood and plywood can be kerfed for bending.

Question 5

Kerfing involves sawing ____ across the grain on one face.

A) slits
B) kerfs
C) bends
D) holes

Question 6

Dry-heat bending is most frequently associated with the construction of musical instruments and works well for pieces that are up to ____ wide.

A) 1/4"
B) 2"
C) 4-1/2"
D) 6"

Question 7

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

Question 8

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

Question 9

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

Question 10

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

Question 11

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

Question 12

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

Question 13

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

Question 14

The layers in bent lamination are called ____.

A) spokes
B) lamina
C) kerfs
D) bands

Question 15

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

A) plasticizing
B) wetting
C) oiling
D) lacquering

Question 16

Plain bending is limited to fairly thick pieces of stock.

Question 17

Two-sided forms require the cutting of two ____ lines, which should be as far apart as the thickness of the material being bent.

A) perpendicular
B) cross-wise
C) angled
D) parallel

Question 18

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

A) blocks
B) clamp forms
C) forms
D) keepers

Question 19

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

Question 20

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

A) 1/8
B) 1/4
C) 1/3
D) 1/2

Question 21

In coopering, ____ work produced containers for liquids.

A) slack
B) dry tight
C) wet
D) tight

Question 22

____ lamination is a method for making curves that uses short pieces of solid stock stacked in staggered rows.

A) Segment
B) Brick
C) Stacking
D) Stock

Question 23

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

A) slack
B) dry tight
C) wet
D) tight

Question 24

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

A) slack
B) dry tight
C) wet
D) tight

Question 25

In coopering, the beveled pieces are called ____.

A) bars
B) staves
C) bands
D) lamina

Question 26

Drying forms, called ____, are placed in the bent wood so that it keeps its shape as it dries.

A) solids
B) keepers
C) blanks
D) holders

Question 27

Milling solid lumber into a curved shape results in a curve that is strong, provided that the curve is less than ____ degrees.

A) 45
B) 90
C) 120
D) 180

Question 28

Bending wood tends to require a great many ____.

A) screws
B) jigs
C) pins
D) clamps

Question 29

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

A) strap
B) board
C) line
D) clamp

Question 30

____ is a method of joining wood strips edge to edge to create a curve, unlike segment lamination, where pieces are joined end to end.

A) Paneling
B) Staving
C) Coopering
D) Beveling
