Due to more pressing projects its taken a while for me to add the finishing touches to this one, but now my Bamboo Trailer is complete and functioning.
I wanted a trailer that was light, strong and fairly cheap to make. A neighbour has a wild patch of running Bamboo so was too happy to allow me to cull some lengths for my project. I also had in mind moving stuff around my 5 acres and the future possibility of hitching a cart/trailer to some goats. All these factors influenced my final design.
Thus I built my trailer with two long lengths to be hand held or mounted to a goat harness yet can still be hitched to a bicycle when need.
A note on Bamboo – let it dry out before you start building. I left mine for 3 weeks, but I think it takes at least 2 months to dry. As Bamboo drys it shrinks slightly.
The ultimate size of the trailer is up to you. The width of this unit is 1m.
Materials used here are;
Bamboo up to 25mm diameter, discarded bicycle inner tubes x 2, second hand 26″ bicycle rims and tyres, new spokes and wheelchair hubs, steel axle parts, U brackets x 4, Braided wire, wire clamps, cable tensioners x 2, stainless steel nuts and bolts x 6, conventional bicycle trailer hitch modified with the bend section of an old set of handlebars.
These wheelchair hubs are great as they release with a push of a button. I handbuilt the wheels with stainless steel spokes. The final piece I needed was a cross axle made from 25mm square steel that connected the two wheel mounting plates – adding rigidity. I will have to update this post later with the final weight, but I am guessing near 5kgs.
