I am dealing with some frame rot on the cross member that the gas tank is suspended from. My plan is to build a new one. I was toying with using round or square tubing with 3/16 flat plating. Is this a good plan or would angle be better and what size tubing or angle?

 

Don't know if you have done this yet as it's an old thread, but I'm going to be doing ggit Monday and will update the thread

 

Yes, I missed this too

I wouldn't use "tubing" as it can rust from the inside out unless it is coated or made from rust resistant metals
