@toolstoday: Cutting perfectly centered tenons on both sides of the shelf using the Shaper Origin handheld CNC machine and Workstation is easy and extremely precise! To accurately do this you want to keep the reference faces the same, by having the 90 degree locating pins on both sides of the Workstation we are able to do just that! All of the tenons are now cut on both sides and we are ready to cut the sides!
