Quiz — Simple Stave Gauge: Use and Accuracy

1. What is the primary function of a stave gauge? *

To determine the exact proportions of the staves

To determine the barrel’s capacity

To adjust the thickness of the staves

To ensure a uniform exterior finish

2. What can a simple stave gauge be used to check? *

Only the assembly angle

The angle and chamfer of the head

The final diameter of the barrel

The density of the wood used

3. What is the correct formula for calculating the diameter of a circle? *

D = R ÷ 2

D = π ÷ R

D = R²

D = 2 × R

4. Which mathematical constant is used for the circumference of a circle? *

Phi (φ)

Pi (π)

Delta (Δ)

Omega (Ω)

5. How is the reduction coefficient calculated? (multiple answers possible) *

The body divided by the head

The head divided by the body

(Head + Body) ÷ 2

Body × Pi

6. In the example of a 225-liter barrel, what is the radius at the head? *

34.5 cm

57 cm

28.5 cm

69 cm

7. The additional arc drawn between the head and the bottom is mainly used to: *

Facilitate the visual organization of markings

Decorate the key

Reinforce the stave

Check the thickness of the staves

8. The development of the bottom corresponds to: *

The total height of the barrel

The maximum width of the stave

The circumference at the widest point of the barrel

The depth of the head

9. What is a common drawback of the assembly jig? *

It is fragile and brittle

It is difficult to mark

It may lack precision

It requires a measuring laser
