I’ve made really big circles with the GF, but never in one piece.
This piece is 4 feet in diameter: My first piece of art created on the GF
The largest gear in this one is more than 36" wide: Giant Wooden Gears
If I wanted to make a 22 in circle, I would make it in 2 layers. Each layer would be made up of 4 segments (a quarter circle, 11" x 11"). I would rotate the bottom layer 45 degrees from the top layer and glue everything up.
That’s how the big gears were made (but using many more segments for each layer).
