Bicycle Trailer ep. 7 - Bathtub

Now that the trailer is in working condition, the first assignment was to get the rest of the metal to complete it. Conveniently, the metal store had the exact size piece of aluminum I was looking for to make the cargo bay.

I had to improvise when bending this thing since I don't have any formal fabrication tools, so I clamped a piece of angle iron along the bend line.

I secured it with acorn nuts on the bottom to prevent cutting people or things by mistake.
