The New Hotness

  • MPCNC: Bar Clamp Mounts, Redux

    With the new thermistor installed and the nozzle at (pretty nearly) the right height, the final set of bar clamp mounts came out perfectly:

    MPCNC - reprinted bar clamp mounts
    MPCNC – reprinted bar clamp mounts

    They’re supporting the snippets produced by trimming the clamp extrusions to fit across the bench under the MPCNC; I figure they ought to come in handy for something.

    Both extrusions carry a warning sticker giving the bar’s serial number:

    Harbor Freight Bar Clamp Labels
    Harbor Freight Bar Clamp Labels

    Huh.

    I could be persuaded the number applies to a given production batch, although I’d be unsurprised to learn it’s a batch of labels, not clamps.

    They don’t look much different than the previous versions:

    The main change was to raise the bars by another 2 mm to give one of the clamp shoes more clearance. As you might expect, the top and bottom halves of the clamp castings aren’t quite symmetric.

    The plastic mounts come in mirror-image sets due to that off-center bolt hole.

    Yes, the threaded casting is slightly angled from the screw clamping force.

    All in all, the mounts look pretty good, in a bright-orange sort of way.
