Recently I needed a pulley for a motorized camera dolly I'd built - found an old bottom bracket. Absolutely wonderful things.
As for dynamos, have you considered putting a hub dynamo in the trailer wheel? I had a roller dynamo on my trailer but thought I might replace it with a hub.
Thanks for the comments lads. Sadly I think my trailer has a design flaw?
I tried it out with about 2st of shopping yesterday. Firstly I found that with some weight in box it made the front wheel of my bike a bit light. I think if I had a bit more weight in the box I'd have been doing wheelies on the way home? - Maybe the hitch assembly is a bit long, I may try shortening it. Secondly I found the bike to be a bit wobbly, but I dont know if this is the norm as I have never ridden a one wheeled trailer before.
So it looks like its back to the drawingboard.
