Oliver 10044 - Setting Depth of Cut

26 | Page Oliver Machinery 10044 Planer
Step 2: Setting Depth of Cut
This planer can remove at most 3/64” of material per pass. For stocks that are less than 5” wide, this
planer can remove as much as 5/64" per pass. For best results, it is recommended to take light passes
when approaching the desired thickness.
Wood Hardness
The operator should reduce the maximum depth of cut for wood types that are extremely hard or
extremely soft. Hardwood increases the planer’s workload, and very soft wood species tend to show
degraded finish when receiving aggressive cuts.
For your reference, this Janka scale shows the hardness of wood types that are commonly used. It ranks
the hardness of various wood types by measuring the amount of force (in lbs.) required to embed a 0.444”
steel ball halfway into the wood.
