OK so I got this lounger thing; its aluminum, 1 1/8 OD for the most part; got steel springs and straps in the pic; got them removed; also decided to ditch cantilevering two front forks off the rear; due to the likelihood of permanently bending the rear legs and thus ending up with a wrecked trailer... anyways; I recently acquired two wheelchair wheels; no axles, but they are marked for 7/16" axle bolts....here is what the chair looked like before;
what I am attempting to do is make a cheap version of THIS;
as for the hitch; it will be a form of goose-neck to the seat post area; using a donor bike frame's top tube and head tube, with a cut fork, attached to the cross bar at the front with the handlebar stem; and with a caster wheel at the seat post for two axis pivoting, while the cut fork provides the turning pivot...
I am thinking for the axle, solid 7/16 steel rod should be OK, with threaded ends? or should I try to find 5-6" long carriage bolts with long enough smooth shanks?
these are the wheels I have; and if anyone;s questioning the strength of the aluminum framing material; well; I've slept in the thing several times, without wheels on; and it's held up to me just fine...and there's reinforcement in the hollow legs for the axle to pass through
