The wood I used was an old tray of some sort, I guess that is is teak
I found a 3D model on Thingiverse for the 1911 Colt. Imported that into Vcarve Desktop. Set the cutting depth to ca 9.5 mm.
Created one roughing with 6mm end mill, then did a second roughing with a 1,5 mm end mill.
The finish touch was done with a 0.1 mm 20 degree carving mill.
I have attached the Vcarve-file.
