I once put together parts back on a frame only to find I couldn't get the
rear wheel to spin in the center of the rear chain stays. A few minutes of
looking and I got ready to remove all the parts and it was out in the next
trash collection. A Columbia that had been put aside for a very good reason.
Wish it had become apparent to me before I put all the parts on it

I think I am up to three frames in the garbage and a few donations that look
beyond the effort I wanted to put in them. As I said above, sometimes bikes
make it to the trash (where I have picked up a few good frames) for good
reason!
