For individual construction is often necessary to make processing of logs for construction of wood with different cross-sections (beams, plates, boards). Due to the large weight of logs and the lack of a reference plane such processing conventional saw and planer (without additional equipment) almost impossible to do. This task I chose the following way.
Electric planer with replaceable working bodies (cutters) mounted on a homemade cart, complete with wheels and moving on a kind of rails — rails.
Processed timber is placed tips on dual jacks, mounted on the supports.
