i've noticed on many neck thru's that the neck material itself is on average about 3/16's of an inch above the top of the body then with the fingerboard sitting on that the height in total from the top is about 7/16's. How do you maintain that initial 3/16" when attaching the wings to the neck blank. Should the whole blank be made 3/16" oversized and then remove that extra material from the section that goes thru the body ? Am I making myself clear ? I'm not sure if i'm articulating this question properly. in other words, the neck will not be flush with the body; that would be easy to do. the above looks a little more difficult to me. thoughts ?
