How can I manufacture a bike trailer coupler to replicate this one? Answered
We recently bought a secondhand InStep brand bike trailer to haul the kids around in. It came with one coupler. I'd like another one that I can attach to a second bike so we can easily move the trailer from one to the other.
The couplers are available online for around $10, but for various reasons I prefer not to buy that way. I'd rather try to make something that will work, buying materials locally. I've looked at several trailer coupler Instructables, but none of them seem like they'd work with this trailer"s tongue, and I don't want to modify it, since it works just fine with the existing coupler.
Any suggestions for a way to make a good, strong, secure coupler?
