I have around 80 linier feet of 2x4x1/8 steel tube to use for my trailer frame. This stuff is heavy. After moving twice in less than a year I am getting ready to start my build. I have a utility trailer that I got off of Craig's List that was build by a farmer (this thing is built like a tank) that is essentially three complete frames, one inside and one on top of a third frame, I will be completely disassembling this trailer to start from scratch. I am not terrible at welding so that really isn't an issue.
Not wanting to over build my frame, would it be a good idea to cut this into angle or c-channel for the frame? I could make 2x4, 2x2 angle, or 2x2, 2x1, 4x1 channel out of it in order to save weight, but in doing that will I weaken it too much?
Thanks for any responses.
