Having yet to actually mount the Felder dado set and make some cuts, I figured this would be a good way to do some tests and see for myself the "bat ears".
Each dado measures 7mm H x 12mm W
I cut some white oak without a sacrificial board, no tear out on the cross grain. I've marked the cuts infeed/outfeed. The bat ears measure less than 0.5mm
I also cut some Colorfin plywood. It is notorious for chipping out very easily. The Felder dado set cut it perfectly with no chipout on the face. The dado also measures 7mm H x 12mm W
For what it's worth, the bat ears are barely perceptible. Like Mac said get out your microscope.?This next photo was taken from my eye level with the pieces on the sliding table. You can't see them at all.
Hope that is helpful for anyone else wondering.
Steve
