I need a 1/4" length of brake bridge tubing to make patches for the brake bridge on my old battered track bike. Someone drilled it... TWICE! so I need to spend some time with my jeweler's saw and cut out four tiny circles. Really... just one-quarter of an inch will be all that I need. I'm willing to trade, if there's any bit of hardware you need that I have, and will also fit in a small envelope.
