ElfLeather Report post Posted October 6, 2017 (edited) Hi folks! Long-time listener, first-time caller. I have access to a Bantam Tools Desktop PCB Milling Machine and I want to use it to make an embossing stamp in brass. The way I'm planning on doing it is taking an SVG file, importing it into fusion, extruding it above a surface to give it depth, and making a CAM toolpath to mill it as a relief in 360 brass plate (probably 1/4" stock, but I could do 3/8" or 1/2" if 1/4" doesn't give me enough depth to work with). My main questions are: 1. What's the usual height of the relief pattern on a stamp for embossing? The graphic is about 1.25" in each dimension, and I intend to stamp it into either stiff, 8-12 oz latigo or 8+ oz veg tan. The endmills I have access to can cut to a depth of like 3 mm with sharp definition, or a lot deeper if I don't care how crisp the inside corners are. 2. Are the edges of the relief on a stamp square and sharp, or are they chamfered or filleted? Will a sharp corner cause the stamp to cut or otherwise damage the grain, or do I want as sharp an edge as I can get? 2. What's a good way to ensure that I can easily manipulate and stamp with even, centered pressure? My first thought is milling a groove on the back to put a steel rod (I have a scrap 1/2" tool steel rod I can cut to length) that I can hammer. Is it feasible to just hammer directly onto the back of the flat brass stamp body, or is there an easy solution?
