has anyone made a folder that used some kind of threaded sleeve over the join, a bit like S&S couplers?
or would the sleeve have to be weirdly massive to get some kind of hinge inside and be strong enough?
or could you then have the hinge as some kind of pivot-y bracket-y thing within/on the end of the main tubes which are covered by the sleeve?
