Thanks for all the kind words, folks.  I'll definitely use the mallet, and after the first ding and scratch, I'll get over any damage.  There's always the next one, right?  

Dave P. - I did make another attempt with the spokeshave, but I still could not get the blade protruding enough to cut without closing the throat.  The blade seems sharp enough.  I'll need to spend more time with it to work out what I'm doing wrong.

Duck - Maybe one day I'll get a Shaper, but for now I'll suffer in silence while using the CNC.  😆
