I have white oak 2x1 inch white oak planed, and am not planning to add an extra fretboard thickness. The frets will go into the oak. I am planing to route the squareness off the back of the neck, so bearing this in mind what would be a safe width for the playable area.
It will remain 2x1 through the body, for the bridge fitting.
I thinking 1.5" width by .875" height as many necks start out with a 1.5" x .75" stock with an added .125" fingerboard but .125" thicker shouldn't be a deal breaker unless used by someone with small hands?
Many thanks for the replies, and Wayfinder I am intrigued by your 2new neck mounting methods, as every time I think I have it planned out in my head,I then see where the internals of the neck are better not touching the front and back of the box thereby cutting down on the resonance.
Also routing a well for a pickup, needing the internal of the neck to be beefed up.
So knowing the best way, would be great.
