A while ago, Dave asked me to build him some wheels. He wanted this hub, those rims, and black spokes. So, I gathered everything up, and started to work.
To get the correct length black spokes, I had to go to my favorite shop and have them custom-cut the correct length. I got a couple of extra spokes, just in case there was a problem.
Thing was, there were three problems. Three of the spokes had bad threads, and I had only gotten two extras. It was Saturday night. I was one spoke away from being done. And, the shop was closed until Tuesday.
So, I dug out a regular, silver spoke, and finished up the wheel build. Then, I took my Testor's paint pen, and carefully painted the silver spoke black. I told Dave what I had done, and told him I would replace the painted spoke with an actual black spoke, when I could.
I guess that was a couple of years ago, and that painted spoke is still in the rim. I had coffee with Dave, this morning, and he reminded me of this story.
But, as he put it, "You still can't tell which spoke is painted..."
