As some of you may have seen, I am repairing a 1842 Springfield rifle by grafting on a piece of walnut at the rear of the barrel.
It's been a long time sense I worked with walnut and I had forgotten how easy it is to work with.
When I say easy, I am comparing it with Curly Maple.
Knocking off chunks of wood by splitting it along the grain is easy so getting it down to a very rough shape happens fast.
Sanding walnut across the grain removes vast quantities of wood easily getting the very rough shape down to a "close" shape.
Sanding with the grain removes the wood in an easily controlled manner, leaving a nice smooth surface.
Using (English) chisels sharpened to razor blade sharpness, walnut cuts just about as easily as Balsa wood does with dull razor blades. You just have to remember which way the grain is laying so your always cutting down thru the grains and not chiseling against the grain (see "splitting" above).
My only negative comment at the moment is that it is easy to accidently chip out little pieces if too much pressure is exerted by an inletting chisel in the direction of the grain.
Great wood to work with, and I know it always finishes out to a beautiful surface with a little linseed oil.
