The Progressive Stakes are used after a piece is formed with the F-2 Doming Stake.
The F-2A is the first stake to follow in the progression to form concave flutes. This stake establishes concave curves without making the flutes sharp. The next two stakes, F-2B and F-2C bring the high points into sharper relief.
