As if I don't have enough projects going on, I want to undertake building a trailer for my commuter bike so I can do full on grocery trips etc. I've been searching and searching for a good hitch method.
I've decided I would prefer to use a seatpost attachment (as opposed to an axle attachement) as the interface between bike and trailer. Now, I could do something that allows only side to side movement like many trailers that mount to the seat post or frame, but I would prefer to have something that will allow me to lean the bike in turns without toppling the load.
The picture below shows how Cycletote (http://www.cycletote.com/) does their hitch - a minerature ball hitch. This is exactly what I'm looking for. Anyone have a source for something like this? I tried my old stand by McMaster-Carr (http://www.mcmaster.com/) but they don't have anything. They do have some minerature universal joints, but anything that is on the reasonably priced side isn't load rated and I'm suspecting might not hold up to repeated use with heavy loads.
I've done some extensive searching on the internet, but I'm coming up dry. Any help would be appreciated. I can still consider a single arm frame axle mount design with the same characteristics (think Burley (http://www.burley.com/) trailers), but still would need a reasonable priced hitch.
Thanks in advance.
