Cool build, but a little reading in how mills and lathes are made would result in a much better machine. The Gingery machine shop series is cheap and good to read even if you don’t want to pour aluminum - his machines also make some bad compromises, but the books also inform you of things that would make you do machines like this different if you knew them.

I totally read that as killing machine and got confused.

Almost as solid as this DIY build from a redditor
