I’ve finally finished my St. George medallion carving and am quite happy with the results.
The wood is pine with a Danish Oil finish. For the final pass I carve used a 1.5mm ball nose bit with a step over of 0.2. A step over of about 0.1 would likely have been better, as I had to do a fair bit of cleanup with a dremmel and some sanding. Its probably at the limit of the detail that pine can hold. If I was doing it again I’d either use a hard wood or make it bigger.
You can find the original 3d mesh here. I did re-model the meander (the squiggly bit around the outside) so that it could be carved with a 2mm bit.
