I'm making some toys for christmas and I have to make a ton of wheels for all the cars and trucks. I've been using a hole saw to cut them and then putting them on a dowel and using my rotary tool to round the edges and give em a bit of a clean up. Then I hand sand them to make them pretty. It's a very long process and I have to do it over and over again. Anyone have any ideas how to speed this up? I was thinking about buying the dremel router table attachment and routering the edges of the wheels to round them, but of course then I have to buy a dremel rotary tool as well(mines a knock off, but it works great). So any ideas for a jig to make this a bit easier?
