So looking for an answer to a question and this seemed like the most fitting thread...I also have some sugaring on the interior of my welds (not nearly as bad as some pictured before) but I'm looking to grind them down as well. The question: What is the best tool to grind down the interior welds? It seems like my 4 1/2" grinder wouldn't work to well due to the confined space. Has anyone used a dremel to grind them down? Do they work well? Seems like a good choice for the small space but are they actually powerful enough to grind down the welds?
