Good Job!
Bravo on your trailer project!
For some reason, a custom built trailer is always something I've wanted to build . . . for the last 35 years.
My father-in-law is giving me his welder, so maybe next summer I'll give mine a shot.
I like how you used the forks for the wheels - that has always seemed like a good idea to me.
Have you posted this to Instuctables.com? They'd eat it up!
