Instructions on how to build a tough and light bicycle trailer out of standard light gauge angle iron found at the hardware store. This design is tough, relatively light, easy to build and easy to customize.
Step 1: Collect Tools
Tools required for this job include --
Adjustable wrench (two)
Ratchet with 5/16 socket
Drill with phillips bit
If you have a circular saw, it may be easier than using the hammer and chisel. Eventually I got sick of using the hack saw and borrowed a friend's angle grinder with a cutting disk.
