The completed stummel is usually made of molded steel so it doesn't wear down over hundred of uses perhaps thousands when I saw them they have to be at least 10 years old and they have one for every shape they produce.I'll go halves with you Chris theft are about 20 large.

I agree with your suspicion. Serious money at work with this one. Making the 3D model is a big chunk of the battle. I've seen a similar machine that uses sanding belts. This one makes more sense to me because it is much more versatile inre the shapes it can produce. If one wishes, it can be micro-stepped and the sanding required after machining is minimal but production slows way down.

I have ideas for simple copy machines that will do 90% of the rough shaping. Problem as always is space and time to actually work on it. I'll probably do a stem machine first since that is easier and more compact.

Did you see the video I linked? The master is definitely briar, or they’ve got some beautiful grain on their steel... I saw the machine in action a few years back and I’m convinced that master blank was wood. It doesn’t a lot wear because it’s a simple sensor wheel running against it, and since they make 8 copies at once they can easily save one as a future master...
