Aluminum bar stock rotary milling test
After the first test of the Sherline rotary table on the mini mill, I wanted to try something tinier, and see if I could mill it more tightly, and more cleanly, by cutting my initial cuts each at 1/1000th inch intervals, and then increasing after that. That should give me clean corners at the top edges of each cut, I figured. Mostly, that worked out to be true, but this Home Depot 1/4"x3/4" stock is too gummy for really clean cuts. I need harder stuff for really nice parts-making.
