I'm hoping you guys can steer me the right way on a cosmetic issue.
I made about 30 square feet of end-grain walnut butcher-block countertops for my wife (2.5 gallons of Titebond III by the time I was finished.)
I took them to my buddy's shop to thickness them on his enormous CNC router. We put them on the vacuum table and used, I think, repeated passes with a 1" bowl bit to surface one side, then flipped them and used another series of passes to bring them into parallel.
Cool process. And the result? End-grain butcher block that's dead flat and precisely dimensioned, but which also has router striping I can't seem to sand out.
I've spent two days using a random-orbit sander to take the countertops from 40 to 80 to 120 to 220, but the stripes persist.
I could, I suppose, take them to someone who's got a big drum sander and run them through, but I'm worried I'd be closing the door on the stripes only to open the door on snipe, scorching, edge blowout, etc.
So, CNC router guys: how do I get rid of stripes on end-grain walnut countertops?
