Use your drill press in reverse to make perfectly centered holes

Vik Olliver put up a great tutorial about how you can successfully drill down the middle of a shaft using a standard drill press and cheap vise. To do this, you drill the part backwards, by putting the drill bit in the vise and the part in the drill press chuck. The trick is that you can line up the vise precisely by placing the drill bit into the chuck upside down, lowering the tool, then using it to align and clamp down the vise. Once the vise is secured, you release the drill bit from the chuck (but not the vise), and put the part in the chuck. Of course, a lathe might be preferable, but sometimes you have to work with the tools you have! [via Hack a Day]

      Ah, thanks for the correction! As for all Makers being virtuous people, well, maybe that is true as well!

    Neat trick, and helps to stop the distortion of the drilled piece by having more contact patches than the (2) on the vise.

    Link to a good book from the Hack-a-day comment list-

      What system/browser are on you, Volkemon?

      I know our IT folks are diagnosing a problem now with IE on PC and cookie caching.

        Hm… I will email you on this so my compooter ignorance isnt displayed for all to be amused by ;)

        IE on a PC is a good description, however.
