Start by laying out your braces on the back. You can use math or your eye to determine the correct spacing. It is wise to space the braces evenly.
Using a square… square the braces to the centerline.
With a Pencil (flattened on one side), mark the brace locations on the center strip. The flat side of the pencil should be held tight to the side of the brace to ensure an accurate projection of the brace width.
Choose a sharp chisel and cut down (just inside the drawn lines) in a slow rocking motion. The final slot edges will be cut once the center is hogged out.
Hog out the slot center with a smaller chisel (bevel down).
Cut the final slot edges (bevel toward slot). If you leave half of the pencil lines, you will have a snug (but not tight) fit.
Test fit the brace.
Continue cutting the slots for the remaining braces.
Place the back in a gluing or sanding bowl with the desired radius (usually somewhere between 12′-20′), place the bowl in your gluing area (go-stick bench for this article), and start applying glue to a brace.
Fit the brace into the slot. Hold it square, and add some pressure in the center to give the brace tack. Add one go-stick to the center. Once the brace is aligned, add more go-sticks.
Clean the glue after each brace is glued. I prefer a small metal scrapper because it doesn’t smear the glue.
Continue adding the remaining braces.
