modernwizardI decided to make forearm crutches for Brandeis because her cane ain't the appropriate height. Also, as it's very lightweight, it falls over and does not bear weight.
First, I acquired a protractor from Wikipedia. I then acquired a representative photo of a forearm crutch in profile. Then I overlaid the protractor on the picture of the crutch to determine the major angles involved in its construction.
