my 37 grille has dents in the verticals on either side of the crank hole probably caused by sloppy cranking. does any one know how to repair it or someone that does? thanks in advance
My '40 grill had the driver's side flattened in the upper portion. I took a 1/2" x 2" hardwood board (very fine grain), sanded it down to the same width as the inner part of the bars and cut the curve I wanted into one end. For most of the repair, I just rubbed it hard in each bar from the back. On the really bad ones I put it in place and tapped it with a hammer. I still have a bit of work to do on it, but the method has worked pretty good so far.
Then again, I'm not familiar with the '37 grill construction. Is it solid bars? If so, I think a couple pieces of hard wood that will fit between them could be tapped on to straighten them. Using wood for this doesn't leave any marks on the metal. Go slowly and work from both sides to straighten and space them. If it's folded sheet metal, sand a piece that will fit inside and another that fits between them. Six inches long is a good length for working and for checking the straightening and spacing process.
