Mark, if you are asking about the large flag I am working on. . . .
I used a 10mm HSS cutting 5mm deep at 350 IPM. Stepover was 7mm (70%). Roughing time was 1hr 42min
Finishing was a .25 ball nose at 150 IPM. Finishing was 5hrs 21min
The blank size was 38X24X2.75
Here is a link to a video of it cutting:https://www.youtube.com/watch?v=tFA_1PJS32U&t=54s
Sanding and clean up, all afternoon.
I am not real thrilled with this eagle at a large size, way too muddy. So I got out my carving tools and am giving it some definition. It wasn't the .25 ball nose, it was the model itself. Someone went ape with smoothing or something. When it is all done I will post it up here.
