We've had some problems machining pecan...any suggestions?
I worked with a plant about 10 years ago that tried to machine pecan and hickory with minimal problems. The secret was three things--1) double check the MC to avoid pieces under 7% MC; 2) take a light cut (i.e., not much stock removal on each pass); and 3) feed slowly (about 20 cuts per inch).We did not use any jointed knives. Hope this helps.
