I have tremors in my right hand. A few years ago, a company made scales with slots in them, which would help. Are they still in business?
Michael Dresdner: I think you mean the Incra Precision Marking Rules. Each rule has a series of precision slots and holes cut through it at 1/16″ and 1/32″ increments. They make corner rules, standard rules, square rules, and even a protractor.
