Rotary Veneer Cutting Characteristics of Young-Growth Redwood

An intensive study of rotary’veneer cutting of young-growth redwood was made using a research lathe. Seven variables (growth rate, heat method, heating temperature, lead, gap, clearance angle, and nosebar type) were investigated to determine their influence on veneer quality as measured by uniformity of veneer sheet and depth of lathe checks. Growth rate, temperature at which the bolt was peeled, nosebar type, and gap (horizontal nosebar opening) were the variables found to have greatest influence. In general, the results indicate that veneer produced from young-growth is equal in quality, using the foregoing criteria, to that produced from old-growth.
