8. On some extremely deep or wide cuts, some prior stock removal will be required before molding. You
may remove this stock using one of the rabbet knives found in our catalog, or you may use a dado blade
on a table saw.
9. Do not cut a wider stock area than the knife was designed to cut. This will cause excessive heat in the
knife, burn your stock and puts a harmful load on the feed system.
10. The roll pressure screws are set at maximum molding pressure from the factory. They are screwed into
the head as far as possible and the check nut is tightened.
11. When you use the machine for planing you will need to reduce the roller pressure. Loosen the pressure
screw lock nut and screw out each pressure screw ¼” and retighten the lock nut.
12. To change the molding knives, remove the chip deflector by lifting it up and pulling out the pin. Set one
knife at a time in place with the bevel edge toward the in-feed end of the machine. Firmly push the knife
down against the arbor lip and sideways against the bolts in the direction of the tube side of the machine.

GUIDES
a. Guiding your stock
b. Your machine comes with a 14” flex guide, a 14” solid guide and (4) C clamps to guide your
stock. To set these guides, first attach your knives to the knife arbor in the position you have
chosen, often a place where you can get the most out of your roller surfaces. Panel knives would
go to the far right. Smaller knives to the post side half of the mounting area and larger knives to
the central positions.
c. Roll one knife down pointing to the machine bed and place a sample piece of stock you are going
to mold on the bed. Align the stock to the knife profile and carefully lower the machine head
until the roller puts pressure on your stock to hold it securely.
d. Attach your flex guide to the side of the profile that will cut the least deep into your stock. This
will give the longest possible life to your flex guide. Attach both C clamps putting about a 1/32”
amount of pressure on the flex part of the guide. This will keep you stock from wandering within
the glide path. Angle the bodies of the C clamps away from the stock path.
e. Attach your solid guide on the other side of the stock. Push it up firmly against the stock and
install and tighten both C clamps angling the body of the clamps away from the stock path.
f. Remove your set up piece of stock by raising the machine head, and pulling the stock out from
the bed.
g. Your knives will usually cut into one or both guides. This is normal and expected. The guides
are effective and last a long time after being cut into many times.
As you become more familiar with the machine and its use, you will want to make wooden guides to suit
specific jobs.
Mold your bevels or bottom knife cut first when molding bed or crown
moldings. If ordering a custom bottom bevel knife you can have a key path cut
as a guiding mechanism for your top profile. Angled bottom cuts in crowns or
bed moldings require special attention. You must make a sample of the bevel
and top profile to see if everything is set to give you the result you desire. Once
a good sample is made use it to set up on in the future.
