Dross chipping mofo

I went to the store to get a new wire brush for my grinder to knock some dross off of one of my projects. I walked by the power tools section and saw this Dremel vibrating sander thingy and it had all sorts of options for chisels and spades. Couldn’t pass it up. I put a rigid scraper on it and it friggin blasts dross pretty impressively. Originally my method was jamming the tool head on into the line of dross but if you just slide it alongside the line, it chips it off pretty impressively.
