This will be my first project on carving a topographic map on blue foam for some of our students project (study of the surface of planet Mars).
Do you have any suggestions on what end mill to use (from the SB starter kit) and what RPM/feed speed to use ?
From the research I did until now, I was going to try the 1/8 ball nose (77-107) at 18 000 RPM and 4 IPS. We have a Buddy 48-12 with a HSD spindle.
Thank you,
Antonio
