    Hi Guy's,

    Hope more than 3 of you were able to view our article in Digital Machinist Magazine!

    IT was much more concise and to the point than what I presented here!

    Hi All,

    Greg & I have begun modifications on our current design of the Bridge Mill.

    The latest configuration will expand on our spread upright design which was
    shown earlier. Enclosed are some sketches of the proposed design.

    Proposed Changes:
    1.-Add 2-3 inches to the height of the Bridge Columns to raise the existing Cross Bar.
    2.-Add two extensions to the existing Base Plate to add a footing for the extended columns.

    I've removed the patterns from the shed and have started work on the modifications.

    Hope to show some Progress soon!

    W. (Ted) Smith

    The New Configuration Bridge Mill is finally in work!

    The revision to the Pattern for the Side plate is in work and 3.5 inches was added to the height.
    This translates into an additional 3.5 inches in Z axis travel or 11.0 in. total.

    We anticipate adding the wings to the Base plate will be a little more time consuming but
    this modification will allow increasing the machine table from 11.5 x 12.0 to 12.0 x 16.0 in.

    It is our intention to increase the work area by passing long pieces both front to back as well as side to side.

    more progress next time!!

    The next task in the Bridge Mill upgrade is to add "wings" to the Base Casting.

    This revision should not be too complicated because there is adequate space available
    to add the two extensions ( wings).

    Before Modifying the Base Plate Pattern to incorporate the wings
    I decided to test the concept by adding the wings to an existing Base
    Plate casting !
    Looks like some additional machining will be required on the prototype
    but think to results should be interesting!!
