Step 8: This is a bit tricky, align the 4 posts of the base plate with the cap. Sandwich the spring between them. You will need to gently rotate the shaft around to properly seat the spring. It works best if you center the spring, then start to press the pieces together. Rotate the shaft in a circle with your thumb, and it should seat. This may take patience. Don't force it or you will break the posts off your base plate.
