knob shown locked to position 4
Thanks everybody for the kind comments. I was pretty nervous wondering what you all would think. Glad that is done. :tinfoil:
Sorry for the boring
video . I could have shot it a few more times and it would not have been any better. Only dancing girls could have fixed that video.
Some of these pictures are macro photography and show great detail. But in reality the knob is tiny and this level of detail is not easily seen. I wanted this part to be almost like jewelry. The dice dots are only .016" in diameter (that is way smaller than your 0.5mm pencil lead). That was cut by plunging a 1/64" endmill. Then the black epoxy is spread on and the knob put in a vacuum. There is no other way to get the epoxy down in the super tiny holes without lots of air bubbles. Then the epoxy is cut off with another OP on the CNC lathe. And finally the part is polished on the robot with a special clamp/cap over the crown to keep it from being smoothed off by the buffer wheel. The crown knurl is what you grab with your fingers so it needs to be left alone.
Soon I will show the internals of the Vegas Knob so you can get an idea of how it works.
