Just to clarify, there are two basic types of puzzles we scrollers cut. Jig saw puzzles, and standup puzzles. Jig saw puzzles are usually cut from a good quality 1/4" plywood like Baltic birch. Stand up puzzles are usually cut from 3/4" -1" woods. You assemble them laying down, then you can stand them up.
The puzzle blades are a 3/0 skip tooth blade and are designed for jig saw puzzles.
For stand up puzzles, I use either a #3 or a # 5 Flying Dutchman Ultra Reverse blade.
