Positioning the Blade
The blade's curve is dependent on the shape of the guide and its alignment with the guide in determining the contour that is cut into the piece of cane. The blade and the guide must work together to achieve good results. To do this, the blade needs to be aligned correctly with respect to the guide.
If there is not enough guide present for a specific area of the curve, the blade will be too active and tend to rip cane instead of cutting it cleanly. This results in very inconsistent measurements and a tendency for the cane to migrate up the bed in that direction from the "pulling" action of the blade.
If there is too much guide present for a specific area of the curve, the blade will not cut enough and the guide will rub. This can cause the cane to migrate in the bed as well. The guide is actually "pushing" the cane away. If the guide rubs too much, the machine will actually stop gouging. It is actually healthy to have a "slightly rubbing" guide/blade relationship.
In the following procedures, we will assume that the blade and guide are shaped well for each other and that there just needs to be some positioning adjustments done to the blade to improve the action of the machine.
