I am fairly new to woodworking and am trying to be somewhat anal about safety. I understand why you shouldn't use a side featherboard after the saw blade on through cuts, but what about for non-thru cuts like grooves and rabbits? You can sure lock the piece down with top and side featherboards. And then using a push stick keep your hands well away from the blade. Is there a reason a person shouldn't do that or a better way? Thanks.
