OK. I saw this post on the day it was posted and I have taken a long time to comment - partly because I am not as experienced as others on here - however, having seen recent posts about people not commenting etc., I thought I would make my comment anyway. So here goes. Warts 'n all.
I love the walnut and the finish you have gotten on it. The transition between the walnut and the pewter is lovely - I think if both were the same colour it would be difficult to see the joint. However, I do not like the work on the pewter. You DID say some of it was due to tool 'chatter'. To me, it all looks like tool chatter. For me, it is fuzzy in definition and imprecise in design. It looks as though it would be rough and sharp to the touch.
However, I think you have done a great job in 'marrying these two materials together.
Just my thoughts.
