Don't do anything to the ratchets. You need a thinner hand. You can sort through the ones you have, or you can file the nose down on one if they are all too wide. To file down the nose, you use a diamond file and file on the side next to the center pin, just on the nose part that sticks out the hand window. Do about a thousandth at a time, check with micrometer or calipers, file some more, check again, etc.
