In the previous post I showed the artwork for a logo in the form of a circular monogram. This is meant for use in electrochemical etching. After making this artwork, it occurred to me that it might be simplified to the point where it could be engraved using just my vertical mill and its rotary table.
So here is my attempt at engraving with the mill. This is a 5/8 inch diameter brass slug that represents the head of the rear spindle screw of my reel. It has been engraved with a 1/16 inch diameter square end mill. The depth of the engraving is 0.005 inch. When I have taken parts to jewelers to be engraved, the depth is about 0.001 inch.
The final appearance would be enhanced if the bottom of the groove were burnished with an appropriate tool.
I am still working on electrochemical etch and will save this as a fall-back process if that proves unsatisfactory.
