Chopping Upside Down
By putting the moulding in the chopper upside down you eliminate the need for the rabbet supports, which are often troublesome.
Here are some general rules to follow:
- This works only on profiles that have perfectly flat faces (profiles beginning with a 1 or 3)
- It works best on Raw, Sanded, or Oil & Wax finishes − New Traditions finishes are more easily marked and can only be cut this way with more care than it's probably worth
- The backbeveled profiles must be cut upside down if using a chopper to eliminate chipping
- If you use a saw there is probably no advantage to cutting upside down, and there is far greater likelihood of chipping the face − we would recommend against it
