Hi Gang:

An interesting thing to note is these plates are either Right or Left Handed. With the lower hinge toward you the upper hinge can either be on the right or left side. This double sine plate the upper hinge is on the left. When you are designing gages it makes a difference.

will show you what is required and even provides a calculator to do the heavy lifting for the math challenged.
