figure 43. using a rotacator to find BdC.
it is essential that the feed rollers, chip breaker,
and pressure bar are set at the correct distance
below the cutterhead to ensure that the workpiece
moves through the planer evenly and the correct
distance from the cutterhead knives.
to ensure accurate results and make the adjust-
ment process quicker and easier, we recommend
using a rotacator for these adjustments (refer to
Page 28).
if a rotacator is not available, a 6' 2x4 cut into two
even sized pieces and a feeler gauge set can be
used, but care must be taken when jointing the
wood to achieve accurate results.
