Thanks for the kind words guys and gals.
As Chris has said, Macadamia grows into quite a large tree that gets the edible and tasty nuts growing on it.
This one was a storm damaged tree from one of my neighbors , the darkness between the medullary rays could be a bit of spalting that has started, it has nothing on it except a CA finish
Hard to tell from the picture but looks like there might be some scratches still in there near the edges. Did you use any kind of polish at the end?
I think it must be just the grainy nature of the pictures, I cant see any scratches on the pen itself.
I sand 400, 600 W&D, then all the way through the MM range, then use Hut plastic polish, then a coat of Mcquires carnauba wax.
I'm still learning the CA finish, but I am having more luck with it now than I was at the start.
