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.

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.
