Hardness of Lenga
Lenga is generally easy to work with both hand and machine tools. It planes, turns, bores, moulds, and mortises well to yield clean surfaces. Lenga glues well and can be sanded easily. Steam bending properties are rated from fair to good.
A common measurement of wood hardness is the Janka hardness test. The test measures the amount of force required to embed a .444′′ diameter steel ball halfway into the wood. The results are shown in the following table.
