Thanks, I've been making my own arachnid cages for a couple years now so I have used both my dremel, and my soldering iron..
I know some people prefer to use a soldering iron, but I've always liked the dremel more.. I only use the soldering iron when I need to cut pieces of something out (small hides and that kind of stuff) so there will not be a rough edge.. but for making holes I like to stick with my drill, it leaves a cleaner hole then a soldering iron does
