OPERATIONS
Before using this planer/moulder, inspect each and every
workpiece for the following problems, and be familiar
with the hardness of the wood.
• Each workpiece must have at least one flat surface to
slide along the planer/moulder table. To create a flat
surface, pass the workpiece over a jointer (see Figure
33). Defects such as twisting, loose knots or severe
cracks may make the stock unusable.
• When possible, square up stock before moulding.
Plane equal amounts on each side of the board to
reduce the chance of twisting or cupping.
• Recognize the workpiece density. Planing is more
difficult in hard species of wood and may require
several shallow cuts to reach the desired thickness.
Figure 34 lists the hardness of many common woods
based on shear strength.
• Only use clean lumber. Scrape off all glue from joined
boards before processing. Remove all dirt, nails,
staples, imbedded gravel, etc. from any workpiece
you plan on using. Metal or gravel in a workpiece will
instantly damage the knives.
• Avoid processing a workpiece with a high moisture
content. Wood with more than 20% moisture, or wood
that has been exposed to rain or snow, will cut poorly
and cause unnecessary wear on the knives and motor.
• Process ONLY wooden workpieces. Never process
particle board, plywood, MDF, laminates, or other
synthetic materials.
• Feed wood in the same direction as the grain. Never
feed end-cut or end-grained lumber into the planer/
moulder.
