George,
I’m a relative neophyte builder but I have done two in walnut. I have a love/hate relationship with walnut. Rough shaping was fairly easy. Detail work was more challenging. The two blanks I had were chippy. Tight inlets were a chore but looked good in the end. I did have more than a few patches but most are nearly invisible.
I love the way walnut finishes out, if you take your time. I did not fully fill the grain on my second. On the first, the grain was so tight it didn’t need much to make it nice and smooth. Incidentally, the first I did had a knot right in the middle of the cheek rest. The swirl looked like a wolf’s eye. Turned out pretty cool in my opinion.
Regards,
Paul
