Sufficient ties for the test were piled near the planer before work was begun. It required one man to work the planer and one man to handle the ties to and from the table or supports where the work of planing was done. Later on, tests were made of peeling ties by hand and the figures below are a comparison of the cost of the two methods. It was found that the air planer did the best work with air pressure of about ninety pounds per square inch. Digitized by VjOOQIC 234 Eighteenth Annual Meeting...
