M1842 Posted June 3, 2022 Share Posted June 3, 2022 (edited) So I have a very nice looking upper grill bar that gax a crack in the back end, probaby 12-14" long. Will this crack through to the front eventually? Should it be repaired? How would you go about fixing it, muggy weld? Something else?

lugarsu Posted June 4, 2022 Share Posted June 4, 2022 I had the same problem in my 1951 Super 56C. Muggy weld worked perfectly. Even put some reinforcement in the back. Can be replated if needed Link to comment Share on other sites More sharing options...

M1842 Posted June 11, 2022 Author Share Posted June 11, 2022 Made to attempts with the muggy weld, first didn't stick. My fault, I didn't prepare the .surface. second attempt after cleaning was more successful. Looks like I need to go back one more time to close up some small holes. Wasn't pretty and used most of a entire stick of welding rod. Overall, easy to use, short learning curve. Hope it stabilizes the crack so it won't keep getting longer. 4 1 Link to comment Share on other sites More sharing options...

KAD36 Posted June 13, 2022 Share Posted June 13, 2022 What was chosen for heat? Any tips on technique other than cleaning? Never heard of this before…. Link to comment Share on other sites More sharing options...
M1842 Posted June 13, 2022 Author Share Posted June 13, 2022 Propane torch, apply Flux to cleaned area, apply heat around the Flux until it turns brown. Apply rod to Crack and let the metal melt the rod. No direct flame on the rod. The rod melts at 350f half the melting point of pot metal. 1 Link to comment Share on other sites More sharing options...

I used files because I had built the patch too high. I think with medium and fine sand papers I can get the surface a lot nicer 3 Link to comment Share on other sites More sharing options...
