  1. I am considering getting a small drill press for electronics
    repair...what suggestions does the group have?

    Thanks

    One that does what you want and costs what you are willing to pay for
    it....

    I've been repairing electronics for 35 years and can count on one hand
    the times I wanted a drill press while performing a repair. Get a
    Metcal soldering iron instead.

    At home I have a 15" Delta floor drill press and the drill press
    adaptor for a Dremel. Go check out Harbor Freight, Home Depot and
    Sears.

    Get a good woodworking or metalworking one. Make sure it can take your
    half inch bits (as a fellow reader of the wRECk, you'll understand) and
    don't worry about the small ones. If your chuck won't hold them, get an
    adapter. (My Ryobi held a #80 bit with no trouble.)

    Like wise - and for 37 years now. I have a 'standard' home power drill and
    stand that I use for anything over about 2mm, and a hobbyist 12v high speed
    mini drill kit, that has a drill press stand and flexible drives, cutting
    and grinding wheels etc, for anything below 2mm and PCB drilling, and any
    jobs that need hand access. I have owned this kit for the whole time that I
    have been involved in electronic repair work, and never needed anything any
    more specialist. I agree with GG, your money would be better put into a
    decent temperature controlled soldering iron, or better yet, a desoldering
    station.

  6. I've been using the smallest "real" Crafstman drill press for about 25 years.
    (Probably called a 6 inch or 8 inch model.)

    They are usually less than $100 on sale (and that price doesn't seem to have
    changed in 25 years!). It will hold very small bits with no detectible
    runout, but is large enough to handle medium size jobs. I have a 15" drill
    press as well but that gets a lot less use.

    What do you want to do with it?

    Hmmmm, maybe drilling out riveted transistors??

    I usually use a drill press for construction. There is one widely available,
    and they are about $39. I have one and it pretty good for that money.
    If one needs to drill PC holes, I don't know how much precision is
    necessary before you start breaking drill bits.

  10. So I take it that no one has a Servo drill press to work on circuit
    boards?

    Exactly what (repair?) work would you want to do on circuit boards, that
    would require such a tool ...?

  12. To access circuits within a multilayer circuit board.

    This thread might hold some interest if you'd quit playing 20 questions.
    Why not paint a complete picture for us? What, for example, do you mean
    by "access?" To what end? How might a drill press assist in that
    endeavor? You've asked for recommendations for a tool, but it's
    difficult to offer those recommendations with any validity if you don't
    tell us what the hell you're doing, or plan to do. I'm going to keep an
    open mind, pending some actual information from you, but so far I'm not
    envisioning a drill press as a very useful tool for PCB surgery.

    Actually I think that this is a very good question and no one has
    really answered with any make and model information for quality
    minidrill press tools. If the definition of "repair" includes
    "rework", "modify and engineer", "ECO", "FCO", etc. this tool
    is _absolutely_ _essential_ in any well-equipped shop. I use
    a Sherline MiniMill, but it is not ideal as a drill press since
    its Z-axis deflection requires many turns of a handwheel. I also
    use the Stahler PCB milling attachments for conventional drill
    presses to clear areas on PCB copper for pads and vias and these
    tools make very good small drill bit holders as well. The
    ubiquitous high-speed hand tool like Dremel is also frequently
    used to drill although I don't use the press attachment.

    There are a class of precision drill presses that ought to be
    mentioned by any one owning one...

    Regards,

    Is "too many tools" your brother, or your alias? You seem to be the only
    one who's particularly enamored of his cryptic questions.

    Check article headers -- I have nothing to do with the original poster.

    I am keenly interested in this subject and perhaps discussion of it
    is more appropriate to another N.G., but since this tread exists here
    I responded.

    I am converting my Sherline Mill to N.C. with a homebrew motor and controller
    set and have stumbled upon an MCU and firmware which will drive the
    mill to create PCBs directly from Gerber or Eagle plot files if anyone
    is interested.

    I also appreciate precision tooling, especially old precision drill presses
    and I would encourage any owners of same to post make and model information
    together with remarks about performance, maintenance, costs and availability.

    The bulk of my "repair" work has been in the industrial space and involved
    fabrication rather than replacement so for me this is a very germane
    "repair" oriented discussion.

    Regards,

    Michael

  19. It is common in electronics development to have multi-layered circuit
    boards.

    Sometimes a circuit design change requires accessing inner layers of
    the circuit board where a trace is located. A small drill press (like
    a Servo) with accurate depth control is used to drill down to the
    buried trace.

    Since I am planning on buying a drill press for the electronics bench,
    I thought I would ask the group what they tend to use to get an idea
    as to what to buy.
