I did this project for a local farrier. He wanted a special stamp made for a run of several hundred. I did all the artwork on the BobCADCAM - including the horseshoe. The cut is .1" and .02" for the letters. It took 3 hrs to run the job. I had an air-hose rigged to blow directly on the bit. Started with 1/8" endmill (which broke after an hour and took a chip off the island - had to restart). I used a 1/32" endmill and a v-tool for cleanup of the lettering. It was a very tedious job - A lot of fighting with the CAM to get it to stop driving an endmill through the middle of features... I hope to get a picture of a finished pad to post.
