The proper relationship of the canter head centerline to the top of the sharp chain is critical to trouble free operation.  Horizontally mounted canter heads are often too high, even for the average diameter log and surging, especially on smaller logs is a huge problem. 

Our Slant Canter prevents surging by maintaining consistent knife angle of attack regardless of log diameter.  With our design the heads are set correctly for every log diameter.  Stout anvils are key to flawless canter performance.  OSI anvils are built to maintain position and provide trouble free operation.  We recommend using solid heads for any canter and can supply any make of heads with our slant canter.  If you are already using solid disk heads, they can be re-used on a new canter.
