I discovered this little trick tonight while using my hand router to flatten & clean out a dado for the leg on my workbench. First, score a line down the middle of wide dados before hand routing. It will make the chips half as wide and won’t get jammed up in the throat of the router. It also seems to offer less resistance that way. Second, if you hold one handle fixed while rotating the opposite handle around it in an arc like fashion, the router pares the wood easier and pulls out less of those long fiber pieces, giving a smoother bottom.
Cool Brent. I knew I couldn’t have been the first one to “discover” that. I just used my striking knife, but that was in soft wood. I’ll remember the saw kerf trick if the knife doesn’t work as well on harder wood. Both ways seem similar to how Paul makes relief cuts to help hog out wood on a curve.
