12.2 Setting feed rollers for molding
The infeed and outfeed rollers will have to be
lowered for most molding operations. The amount
of adjustment required will vary depending on the
size and style of the cutter.

3. Label this block “feed roller molding”.
4. Save the block for future use.
Never lower infeed and
outfeed rollers beyond 5/16” lower than

cutterhead. This will cause severe stress on
gear box and roller system.
When using molding knives wider than 2”, the first
pass or cut will remove approximately two thirds of
the stock. Test cuts on scrap material will
determine the number of passes required to
complete the cut. Never attempt to complete a
cut with less than two passes on smaller knives
(under 2”) and three passes on larger knives
(over 2”). Generally, the more passes, the better
the finish.

Due to the variety of cutters available, it is
impossible to cover every possible set-up. It is very
important to use test cuts on scrap material before
attempting cuts on project material.

This machine is designed and intended for use with
three matched knives in sets. Many companies
offer knife sets that included only one knife and two
counter-weights. These cause severe vibration and
can damage the machine.
