    Spreading the cutter wear evenly while machining box section on a mill

    Hi All
    I was making a toe lift from some square box section today and wanted the ends to be machined This was to aid the welding in getting everything upright and square.
    I did a sort video on the technique I use and hope some will find it useful for their own future projects.



    Milling box section direct in vee blocks, for alignment of vee blocks please see:Machine dogs, simple to make and use.

    Using a machine stop to cut several piece to the same length

    I thank you in advance for taking the time to view the short video and hope you found it to be useful.

    Not only less cutter wear, and avoids long engagement of vertical sections; highly possible the results are more square wall to wall [adjacent OR opposing sides] and closer to a single flat plane...Less cutter deflection.
    So even if an incline is desired, milling across the corners delivers better results, just as thehomeengineer demonstrates. A swivel vise not required; just clamp at angle[s] desired.
    Now, if only we didn't utilize so much 1.5 x 4 rectangular tubing job wise. On those, I bevel-sand vertical sections [shorter] a bit beyond [higher] where milled walls [longer] that are horizontal will be.
    Sincerely,

    ...we'll learn more by wandering than searching...

    Another advantage of this method are larger deepth of cuts can be made.
