    Bed frames are made from old railroad rails. When I need to drill a hole in one, using drill press equipped with a cut off 16d nail, soften spot where hole is to go. Both nail and rail will turn red, which means temper is gone. Then drill with sharp drill, and plenty of lube, preferably using a drill press. As for why bed frames are spring steel, just think about the stress they encounter with a couple 300 pounders making whoopie. On second thought, don't think about that

    What is "Whoopee" ?

    If it's "Whoopie Pies", those are made in the kitchen.

    Please explain, crisp hi quality images may help.

    Any time I have steel that refuses to be drilled I get out an old cement bit.
    Put a sharper edge on it and go to drilling. I drilled through a ball bearing just to show someone I could do it.

    what do you use to sharpen the carbide wings of the cement bit? I thought it had to be something like a green wheel. And what angle do you use?

    A normal stone will do it, but it's hard on the stone.
