View attachment 90548 Ok so I'm tacking along the butt weld seam for the new quarter. Nice beads, everything going well. I keep moving around and waiting etc. No problem. The problem for me always seems to be when I start grinding the welds down as I'll end up with a small ridge/lip on the seam where if I grind it it seems to make the metal too thin. Then when I try to fill pin holes I end up with blowthrough and from there it's a slippery slope such as......filling holes with weld bead, welding from the inside and occasionally a small patch. The seam then ends up being more wavy than I would like (too much heat I guess although I don't go crazy with the welds) but when I hammer and dolly to try and correct sometimes a seam will appear in the metal which tells me it's too thin and I end up having to patch again; round and round we go. Anyway the end result isn't perfect but it's going to need some filler so I'm looking for any advice you may have. Should I call it a day, quit while I'm ahead and let the glass reinforced filler do it's thing or continue to try and hammer and dolley?? In the 'patched' pic I'm basically afraid to grind any more as it just seems to get me nowhere. I'm thinking....'know when to quit' may be a good approach and that filler will take care of the valleys etc. What are your thoughts? Thanks in advance.
