Patch panels
Why is it some patch panels come with the flange already made and some do not. I have found the longer patch panels usually come with a flange. What are the pro and cons of flange versus straight end butt to butt panels. Are the welds better with flange or BTB. I am replacing the lower 4 inches of the bottom back panel on my 30ccpu and this panel is flanged. Now the lower cowl patch panels are not flanged. Need advice and opinions.

Do you want to become a better metal worker or just slam it home and glop bondo to level it? The flange is quick and easy. Little chance of burn through and you do not have to carefully match the panel to the patch. The problem comes from trying to level the metal, especially on such a large flat area such as the bottom of the pickup cab. The important concept to understand is every weld is a shrink point. You correct shrinkage with hammer on dolly hits. You can not do this properly with an overlap seam. With a little bit of knowledge, practice and a shrinking disk you can do some pretty amazing repairs. See my website for more ideas and places to go learn more. |
