Neck Block question

[Metalone72]

I am about to embark on a scratch build and have a general question about Neck blocks. Are they typically flat (the face) where they meet the sides (and neck joins)? I am particularly curious since the scratch build that I am going to give a try to is a Size 1 Martin from a set of GAL plans. From what i recall of the few pictures that where on the plans (and it has been several weeks since I looked at them!) the end where the neck joins had a slight curvature to it. I will have to check the plans again tonight, but I am not sure whether or not they indicate a slight curvature to the block.

I plan on making the guitar with Eastern Black Walnut (Back/Sides/Neck) and was thinking of making the Neck block and tail block from Wanut as well (probably laminate some pieces), this a good idea?

Thanks,
Scott

The typical Martin dovetail block will have a slight radius on it . On the Martin Mortise and tenon they are flat. All the tail blocks will have a radius. That is about 36 in
