When the front literally has no flat gluing surface in some areas and the least intrusive method available to us, is to run a gouge along the area and to take a large shaving with the same gouge from a piece of matching spruce. It usually takes more than 1 attempt, then it’s chalk-fitted and glued on.
I forgot to take a photo after cutting back the shaving but you get the idea.
Very much enjoying having my friend Michiko Hayashi working with me for a while. She is getting all the jobs done I’ve been avoiding for too long! 😆
