Combining this with a measure of its distance (deduced from its orbit around the Sun) reveals the planet’s actual size. Use a carpenters square. Measure the skirt length. These give multiple results. by Jonathan S. I need to measure a dimension to the centerline of a radius, but the radius is 2" and only covers an arc of about 25 degrees. The steps for calculating a large radius segment bend are: Determine the radius of the desired bend. Since this is an internal radius, I'd recommend that the template Stijloor mentions is made for the diameter minus the maximum tolerance (on the diameter, also). The last step is to use a tool with a large nose radius to smooth out the steps to turn away the "steps" so that a smooth curve is formed that connects the corners of the plunge cuts. A chaining pin is used first to mark point C. If the radius fits when the radius distance is swung from this point, a hub with a nail may be set to mark the point.
