We was made this trailer this week, thanks for couple ideas from this site I plan to use him when I go on picnic with my family, to carry barbecue, picnic table, stool, etc. Thanks for couple ideas from this site... my inspiration for this was this and this one,  but it was more expensive option for me (too many PVC parts), and another advantage for me it's free welding... my dear friend Memet was weld all this for free for me.
Trailer it's made from two steel profiles (2x6m) 1,5x1,5cm. Clear cargo size is 95x65 cm and it's very lightweight. We was test him with app load of 75kg, and it's more then good. Wheels are from some small bike (front and back – 20”), second hand normally completely repaired. Hitch is madded from swivel caster wheel from hardware store with one additional metal plate welded additionally, and it's very simple but very strong (thanks to this) . We was decide to put metal net like cargo floor, because my friend was have couple pcs in back yard, and I think that is good solution even it's add little weight to trailer.
Any way, I'm very happy with results, my kid's too.

Materials/expenses
two wheels from old bike=3,12$
new tires, axial for wheel=14,5$
two metal profiles (12m) 1,5x1,5cm=11$
caster wheel=1,2$
bolt, small parts..=5,5$
metal net=free (regular price here approx. 5,5$)
welding= thanks Memet (regular price here approx, 15$)

total=36$

Thank you very much for this instructable. I just have one thing not clear about the hitch. The metal plate is rectangular with the long side facing downward. My question is: how do you stop the metal plate from turning upward when the cart pulls? I have the feeling that just a bolt will not keep the plate firm for a long time.

Thanks for your answer!

Nice trailer! So far out of all the designs I've looked at, yours is my favorite. Just a couple questions:

1. What is the thing that's clipped onto the tow arm's diagonal brace? (Is it a tire pump?)

2. What type of metal did you use?

3. How did you get your 12m of square pipe so cheap? I started looking around at my hardware store and even if I only go with angle iron, I think it would cost close to $50. I'm thinking about trying it with conduit, which would be a lot cheaper, but I don't know if that would be strong enough.

Good idea using the caster wheel as the (swivel) hitch.
