The design must be worked out by eye, because of the nature of the work no caliper measurements can be made for depth of cuts.
It is a 26-inch caliper, and will caliper up to 34 inches diameter.
In case the bottom surface is used, 0.150 must be deducted from the reading of the caliper.
Then the legs are closed to remove the caliper, and are reset to the scribed line.
The scale and object to be marked are fastened in line with one another, and the caliper bar is used from step to step.
The method of adjusting a spring caliper is shown at Fig. 174, H.
Then remove the caliper and measure the distance between the caliper points.
The tailstock center is next set over by guess and a caliper tool is clamped in the toolpost.
In order to permit of ready adjustment of a spring caliper, a split nut as shown at G is sometimes used.
The common sizes by caliper, or diameter of the trunk, are five-, seven- or nine-sixteenths of an inch.
