There are different ways to carve the front, (sound board), and the back of the mandolin. Some shape the outside first. Others start with the inner surface. You can use chisels, gouges and finger planes, or side grinders and sanders. I’m going to work the outer surface first. I’m going to try using a sanding wheel on my drill press.
Before starting, I need a guide to know when I have the shape close. The plans have profiles printed on them. I cut the profile out, glued it to some masonite using spray adhesive. The profile is a cross section view of the mandolin’s body.
The cut the shapes on the band saw. Then I sand them by hand to clean up the shape.The printed profiles are “positive” images. The pieces I’m making are “negative” shapes.
Here is a profile guide against the raw wood of the maple back. Lots of wood to remove.
