This is the latest of my tests to see what's up. I used new down spiral bit to eliminate the "fuzz" I was getting with the up cut spiral. Instead of using the stock collet, I used the Precise Bits 1/4" collet and cleaned the all the seating surfaces, the collet and nut...just to eliminate as much variable as possible. This file was set up at only 0.050" depth of cut, simply to take all the load off the machine to see what happened. I numbered all the 1" blocks in the order they were cut.
