I just finished this off , I got the idea while I was in hospital last time but only now got around to building it .
I built this out of
2 metal sides from a spring based bed ( the blue bits )
1 metal chair ( silver / brown bit )
2 wheels off my 2 daughters long dead 16" bikes
1 old sissy bar from I don't know where ?
A few nuts and bolts I had lying around
And a couple of pressure pack paint cans I had in the shed .
Oh and an old storage container .
The hitch is just a piece of car tyre cut down and it works a treat .
I just measured the box and made the trailer frame a little larger simple as that the chrome piece is the sissy bar part for supporting the centre of the box .I know it doesn't seem like anything special but I built this out of these things to make it strong but it's stronger than I thought I'll finish with some stats .And it fits a childs car seat perfectly with room in the front . It's awesome !
Box 80 ltr capacity
Overall weight 16 lbs
Overall width to outside of the axle 65 cm
Overall length from back to hitch 127 cm
How much weight can it carry without breaking ME , 175lbs , 82kg ,
Cost $ 0.00
