I contacted John this morning and he will be sending a sketch. I will see what I can do for him

Sounds like Mike has a winner

So then is it possible that the older woodworkers used toothed blades to slightly increase gluing surface?

Two thoughts from a not too learned woodworker. Charlie before you drop your pole remember anyone can author a book with His opinions. I tend to go in Daryl’s direction and think the toothed plane was for using hide glue which might be harder to get a truly flat surface on when pressing the veneer down and wouldn’t be needed when using modern glues. Thoughts!
