string test

    Tie a piece of string to one rear forkend so that the string runs along the outside of the forkend.

    Run the string around the front of the head tube and back to the other rear forkend, as in the photo. You could also run the string to the opposite side of the head tube from each dropout and loop it around, to reduce the spacing from the seat tube.

    Pull the string taut, making sure that it's contacting the same part of each forkend

    Use a ruler to measure the distance from the string to the side of the seat tube where they cross. Take this measurement on both sides. It should be the same on each side.

    If the spacing is as desired, and the string test is correct, you're almost done. If not, you'll need to go back to levering with the lumber to correct any error.

    If you find that you've overcorrected on one side or the other, the same basic approach can be used, except that you lay the bike down so that the stays that are too far out are facing down. Run the lumber under the bottom forkend, and, again, over the seat tube, then press down as before.
