So the first thing I did (after milling my tool holders) was to take a little aluminum block and square it up.
I was pretty pleased with the results. This finish was done by traversing the Y axis by hand. My Shoptask will only power feed on the X axis.
Again, all this was done by hand. I wanted to start to get a "feel" for the machine and for the material. Aluminium is heaven compared to steel. But probably anyone reading this is saying something to the effect of "duh."
