BIG 3 axle half pipe trailer

[Doggy]

Then I started on the half pipe. First problem, I dont have bending tool, and it was weekend and I could wait for Monday to go give it to someone to bend it for me. So I started building a simple bender, but didnt have enough material to make it, and again, it was weekend, so I came up with something out of scrap metal I had at home. You guessed it, it didnt came out good But as it was only a prototype for me to learn, I didnt pay to much attention. Hammer was my tool of choice, so somehow I managed to fit it, and started welding it.
Tried full weld, tried spotweld, tested all the combinations to see what works best. That is why it looks like swiss cheese
