Module 6: Measurement
In Try This 3 you had to make assumptions about the maximum and minimum values for the angle of the drain. However, you could reasonably assume that as long as the angle of the drain was between the smallest acceptable value, 5.0°, and the largest acceptable value, 7.8°, it would pass inspection. You are now going to apply this in another common renovation application.

When installing drainpipes or cutting holes for electrical outlets, the tolerance of the measurements is significant. The tolerance in measurements varies according to what is being measured and whether or not it has to fit with other pieces. In the next Try This you will have to decide which side of the tolerance range should be used when constructing a wooden stool.
You may have had an experience in either a construction technologies class or a fashion studies class that required careful measuring and cutting skills in order to piece parts of the final project together. The following Try This activity will expose you to the measurement decisions that need to be made while cutting and assembling a wooden stool.
