I am making a mahogany screen door and will be doing mortise and tenon construction of the frame.
After milling, all of my material is 1 1/4" think and 3 1/4" wide--it is gong to be a solid door.
In thinking about my mortises, I can either do a 1/2 wide mortise that is 1 1/2 inches deep (maybe end 2 if a max out the router bit) or do a 3/8 mortise 1 1/4 deep (or at least that is the cut depth on the bit).
The 1/2 mortise gets me a longer, thicker tenon, but much thinner checks/sidewalls. The 3/8 mortise is more in line with the traditional rule of thirds for a mortise and tenon, but does not get me the depth that will add strength to the frame.
Any advice or am I over thinking this?
