i managed to get together various parts to create a multi-use bicycle trailer.
the main frame is an old car aluminium roof-rack, fitting the wheels was hard but i utilised the tube clamps that came with it (sorry i don't know the correct name of them).
the main axle was too weak so i changed it to an old steel tent pole,
and the cross piece at the front is also a section of steel tent pole.
the metal cage is a fire guard, it's held together with hose clips these are fully adjustable and reuseable.

Here the Roofrack frame is clearly visible as a light grey surrounding the whole trailer. good thing is the roofrack already has loads of easily adjustable bolts so no welding needed.
the central "T" shape is steel i tried the trailer without the "T" but the wheels were dangerously loose whaen any load was applied to the frame. not having the tools to drill through steel i had to improvise with hoseclips which are surprisingly easy to use and very strong.
the metal cage (brown colour) used to be a fire guard, i had to bend the pieces with a Vice and hammer but again quite easy to do.
from this angle its quite easy to note that both wheels are leaning out, i can't seem to do anything about this but it the wheels straighten when weight is put on the trailer.
the hitch, AAAAGH! horrible! its the handle from the top of a scooter forced onto one of the steel poles i've had massive problems securing it it basicaly hooks onto a "U" section i attatched to the bike it worked ok but rattled alot and actually fell off twice whilst in use(which i've since changed to a much safer system!)

a few months ago i had my first "HITCH FAILURE". I had been waiting for a long time for this to happen so i knew what the hitch could cope with. Well I'm still using the same Hitch after a year and my trailer will take loads in excess of what i can lift. including 1 Meter square loads of soil. the Hitch broke after i did a very sharp(more than 90 degrees) turn on my bike and the trailer corner got caught on a wooden post, and pulled/twisted the hitch off the garden hose (it wasn't too dramatic). the flaw was not the coupling or the hose it was the pressure put on the joint when I caught the trailer. basically what I'm saying is the Garden hose,brass joiner system is pretty sound! for huge amounts of weight pulled.
