Number 2 trailer
This is the second trailer I've made, the first being shown here.
This second one was made with aluminium extrusions from a scrapyard, old wheelchair wheels and, the most expensive bit, lots of stainless steel bolts.
The hitch is just some aluminium square section rod cut up with a hacksaw and drilled 8mm, and with stainless steel bolts through it. It's supported by a structure rather messily clamped to the bike frame and anchored on an unused U-brake boss this frame happens to have:
The hitch lets you lean the bike right over to the left for stable loading:
Leaning to the right is not so good - the drawbar can hit the spokes.
The other main feature on this trailer is that it folds/separates down to essentially 'flat pack' components. Here's some older images showing the folding and details of construction.
After a while it became apparent that I really needed a longer trailer, so the chassis was crudely extended by adding on a plank of wood, which held the rear axle assembly. I also added wood front and rear to support long loads over the level of the wheels. This can be seen in several of the 'loads carried' shots below.
