Reminds me of the suggested use of small strips of aluminun beer can as shims in the handlebar clamps of a BMW motorcycle as described in "Zen and the Art of Mororcycle Maintenance" (Need to be of college-age in the 60's). Unfortunately the BMW owner in the story would not use such a common and non-original material in his machine; so his problem continued. I have, and know others on this board have, performed repairs with common materials as you described. Good work, and thanks for the memories.
