That looks great Mike. Not to mess with success, but I think sanding between every coat, and sanding CA with the grain, is overkill and unnecessary. I usually sand every 3 or 4 coats, or when the coat dries a bit less smooth than usual (which is usually the 4th coat or so...) As for sanding with the grain, unless you're still hitting wood, I don't think it should matter. Any scratches you leave in the CA are filled in with the next coat, which will slightly dissolve and mix with the previous coat, so any existing scratches in CA within reason, are taken care of by the next coat. But as many people say, if it ain't broke, don't fix it, and many of us have CA rituals that others feel are not needed or don't work, so if you don't want to take the chance, and it's working, that's great!!!
