Portable sawmill. Portable sawmills are sawmills small enough to be moved easily and set up in the field.

This design was not energy efficient and around 1860 sawmills began to adopt the more efficient circular saw.

Tree spiking involves hammering a metal rod, nail or other material into a tree trunk, either inserting it at the base of the trunk where a logger might be expected to cut into the tree, or higher up where it would affect the sawmill later processing the wood. Contact with the spike often damages saw blades ...
