    Default Aztec Calendar (if it ever finishes)

    This link shows the beginning of 4 finishing cutting files for my 30 inch dia Aztec Calendar.

    The finish cutting file was too big, so I broke the job up into Quadrants.

    http://www.youtube.com/watch?v=CcX1PiVUrXw

    The SB preliminary cutting review indicates about 12.0 hr for each file.
    I rough machined to w/in .125 and am now finishing with a BDP005 Lettering/Carving bit (discontinued by Beckwith D P). (need more hint, hint.)

    The material for the job is edge glued 36 X 36 8/4 Hard Maple surfaced on both sides to 1.5 thick.

    Spindle RPM 18,000
    Feed Rate 1.8 ips
    Stepover = .010

    If the job ever finishes, I will post more pictures.
    This is not V-Carving. I modeled each of the Calendar elements to make about 30 separate components using Aspire 3.5. Maximum ht = .72 inch of some of the details.

    Better get yourself a Snickers bar, that's gonna take a while.

    You could save some wear and tear on your spindle and cutter (heat) by turning it down a bit. I've done many finish passes with 0.0625" and 0.125" ballnose bits at 10,000 - 12,000.

    Scott,

    I tried a larger ball, but then I lose a lot of detail on some of the smaller components.

    Slowing down the RPM increases the chip load/flute. I've used 18K RPM on almost all my jobs with no problem.

    Using your V-Carve vectors, read them into Aspire, then group into individual components and make shapes using the modeling, sculpting and smoothing tools in Aspire.

    Here are three views of the finished carving.

    Total machine time was 50.58 hours.
    This time includes facing both sides of a very warped edge glued plank,
    Rough 3D routing,
    finish 3D routing,
    circle cutting the disk from the square stock and
    V-Carving some identification about the Artist (me)
    and a date of carving and of course,
    the Aztec Calendar Expiration Date (21-Dec-2012).

    Nice!
    That looks great George.
    Kinda wreaked if for those of us who haven't done one yet though.
    How can we be happy with a v-carved one now? Haha.

    When i read 50 hours i thought, boy he had his settings wrong or something, thinking it was a vcarving. That is real nice. Now what do you do with it?

    After I have it stained and a finish applied (by a professional and not me), I hope to sell it.

    I've had the SB almost three years and 3D carved a lot of hobby and give away stuff. This time, I would like to make a few bucks on it.

    Wish me luck.
