“If there is one single piece of advice I can give you for successful duplication, it is to break up the job into many short operations. Do the first step, remove the workpiece and replace it with the next one. Working in this way there are fewer operations to memorize, fewer chisels out at one time, fewer calipers to use (reducing the chance of taking the wrong one and making an error), fewer changes of the tool rest and/or steady rest (one time for each step) and quicker development of ‘muscle memory’.”
