The single fluke threw everything out of balance and were easily broken.
Probably should have said, the single spur and or fluke created "uneven stress" on the bit and they were easily broken.
especially small diameter single flute straight edged cutters. spirals are a bit better ballanced.
Force would be more evenly distributed if the spur was in contact all the way around the bit rotated. Entry and exit of the spur laterally would cause some pretty high instantaneous stresses.
I have done it in both maple and poplar using my delta benchtop. It works. I did not break the bit.
That only means that it *can* be done.
