Hi all I have a new repair project it's a 16ft car trailer.
Needs some work but price was right. A couple of the 2x4 by3/16 tubing is soft I have pounded away at a few areas and made a few holes. Any problems in cutting out the bad areas and patching in some metal?
I'd like to save as much metal/ work as I can . I will have to replace several cross members
Here's a couple of pics the holes are about 1-2" diameter Click image for larger version.
