So made these this last week/weekend:
A guy I work for is making some Ammo Crate boxes for his family and asked me for these so he could put them on the crates. Poplar about 7/16" thick. Bits I used were 1/8" O-Flute (single flute) (FR: 23.6ipm, DOC: 1/16" stepdown to 3/16" and 7/16", RPM: 11,500) and 60* V-bit (FR: 10ipm, DOC: 3/16", RPM: 25,000 - I learned for V-carving that RPMs needed to go way up, and I slowed the feed rate down to get nice clean cuts).
Here’s the finished boxes after he glued them on and then stained them!
Another guy I work with asked for some Master Gunnery Sergeant rank insignias (USMC E-9). Made from black walnut, 1/4" thick. Bits I used were: Center engrave: 35* V-bit (FR: 10ipm, RPM: 25000, DOC: 0.06"), Pockets: 1/8" O-Flute (single flute) (FR: 23.6ipm, DOC: 1/16" stepdown to .25", RPM: 11,500), and V-carve/bevels: 60* V-bit (FR: 10ipm, DOC: 1/8", RPM: 25,000). Pictures are in order of process - engrave, pocket, advance V-carve, contour (bevel on the stripes), contour (perimeter cuts).
Images were pulled form the web and were either already .svg or created from .jpg and converted to .svg through Inkscape. Layout and CAM done through Carbide Create (free version).
Thanks for stopping by and looking!
