My first try with sugru is a great success. The knob on the adjuster bolt for my roller stand broke years ago; I've had a small vice grip on the bolt ever since. Now that I've hacked a new knob, I think knobs (and pulls and such) could be one of the best uses for sugru -- you can easily make them bigger so they're easier for anyone to use -- young, old, frail, physically challenged, or just because!
