Using a Spoilboard

A spoilboard should be used with any operation
the cutter cuts completely through the workpiece.
Typically, a spoilboard is made of MDF that has
been surfaced perfectly flat. Even a new piece of
material should be surfaced before use.
Moisture will swell and warp MDF spoil-
boards. Using a warped spoilboard will result
in damaged or inaccurately cut workpieces
and could result in damage to the machine.
If liquid is spilled on spoilboard, it must be
dried and resurfaced, or replaced.
