I noticed most of the Homebrew CNC machines I looked at (and was modeling my machine after) were just brad nailing or screwing pieces to their tables. But what if you need to work on all sides of the material and have no place or way to nail or glue? Like Acrylic?You could even make a larger one of these for the ShopBot. You have to upgrade to a better vacuum pump. I don't think a shop-vac could power an awesome sized table as the ShopBot's 48x96. You would just have to take this idea and beef it up tremendously to get it on par with the ShopBot,.
Okay let's get going!!!!
