Someone wrote about drilling holes in thin sheet metal. I lost their email but this is how it works and doesn't work. After you center punch the material you can use a series of drill bits to make the hole as big as you want. But the danger is everytime you drill the hole a little bigger it seems to walk. And if you try to use too big of a drill bit, it seems to drill a five sided hole. So the way to do it right with a drill press is either clamp the metal down and use a series of drill bits or use a step drill. The nice thing about a step drill is it always drills the new hole off the center of the old hole. So no matter how big the hole is, its always centered with the center punch mark that you made originally. Good source of step drills is Harbor freight. I usually by the cheap ones. They work about the same. Hopefully this will be the last post in holes. Unless anybody has any more suggestions. I think we about covered the hole thing. Then I will probably get through the tool thing and then I will go ahead and start building stuff. There are some pics enclosed. Thanks to whoever sent me the letter about step drills.
i would like to add, since holes have a lot to do with a drill press, to clamp your material in a vise or to your drill press table. Don't wear gloves or loose clothing around the drill press. Happy motoring.
