that is a nice one....
but If I am to buy machinary again, it will be a CNC-Mill...... I think I have taken the Drill-press to it's max, as far as doable design goes, honestly, for making water-blocks, you won't need anything bigger than the smallest drill-press you can get.....now that doesn't for one moment mean bigger is not going to be better
bigger is always better, and more accurate
