I was always told to use green pegs, and to store them in a bucket of water if they were going to sit for a while. I guess the reason is that when you are drawboring you need the flexibility of green wood. It is too bad that person just cut the frame apart. There are ways to get stubborn pegs out. I have a slide hammer with a lag screw on the end that works well. I also have made pins with depressions on the end to drive the peg back through the hole.
