    Doug,

    I like the design and workmanship. It is a great inspiration for making one. I like the table hole going all the way through for drilling into longer rods.

    I have wanted this type of sensitive table lift drill press after seeing an ad for a Dumore Sensitive Drill Press but could never afford the high price tag. Your video proves there are alternatives. I hope you will be selling your plans at HMT.

    Thank you for all the details.

    Paul

    Thanks Paul
    I always wanted one of these too, but like you say the price tag was way out there for no more than I would use it, I will use it don't get me wrong but I would never buy one at there price tags, so I came up with this instead.
    I am going over the blue prints to make sure things are in order, as you know things change as you build, I'll be sending the prints to Jon in a few days and he'll post them in Plans for sale

    Think about supplying the table elevator lever with an adjustable counterweight arrangement. My experience with my own miniature drilling table lift indicates that a counterweight provides an even more sensitive feel.
    I think that counterweighting is an essential part of making a drill (or table in Marv's case) sensitive. Here is my offering in that direction.
    DIY high speed sensitive drill press.

    The video demonstrates the why and what you can achieve with counterweighting.

    Thanks, Tony for another thoroghly researched, well explained and resourceful build video.
    I know your post is half a year old, but I still got tempted into thinking:

    -I maybe missed something regarding the upward force thru the drill, creating moment and thus drag on the rack:
    Isn't the reason that the spindle motor's moving piece seems to have an open-ended "U" at the column?
    Couldn't that freedom be simply restricted by just adding a U-shaped "saddle" around the column for the moving piece,
    perhaps with an adjustable, recessed decent small ball bearing at the back to make it without play but easily movable?
    Guess you finally could name it "Peerless" after that?

    2 cents

    Johan

    PS: The DeLuxe version would even have a bottom ring with 3 ball bearings 120 deg apart,
    the rear one adjustable thru an eccentric for that tight, smooth ride...
    -But that would of course limit quill travel even further. Oh well, what the heck... Just a thought.

    I like the KISS principle.
