SPECIAL GUIDE SET UP & KNIFE SHARPENING
“V” BLOCKS
The deepest cut that can be made on the molder is ¾”. If your depth of
cut is greater than ¾” and you’re running straight molding a “V” block
maybe your solution.
A “V” block is a cradle that is built from wood on angle(s). By elevating
the stock at an angle, it enables you to maximize your use of the ¾”
depth of cut.
TONGUE AND GROOVE
Inspect stock for cupping and warping before cutting. Plane stock to one uniform size, this will
ensure the tongue and groove fit properly.
Wooden guides are required for cutting tongue and groove. Guide thickness should be 3/8”
thinner than stock or the roller will scuff on the guides when the stock leaves the molder. When
cutting thin stock fastens a sub plate between the guides to maintain a thick enough guide to
control the stock.
Check the knife clearance to the guide. Clear away any interfering portion of the guide by gently
lowering your knife down into the guides to just below the running position.
KNIFE SHARPENING
Keeping knives sharp will prolong the life of the knives and give stock a quality finish. Our
standard technique is surface grinding the (back) of the knives. Sharpening the face may cause a
change in the profile; we only use this technique if the sharpening can be performed without
changing the profile.
Minimum thickness for molding knives is 5/32”
Minimum height for planing knives is 1 3/8”, angle should always be 57
◦
Our in stock and custom knives are manufactured using M2 high speed steel flat or corrugated
material. The molder requires (2) knives of the same profile. Our knives are sold in a set of 2.
