Comments on my first attempt at a design (if you would)

Cheers for you comments. The one about the pillars surprises me i thought 25 x 100 solid steel bar would be over the top if anything. My logic was that the columns only contact at those points and are relieved in the middle of the base, so with the 25mm thick flat bar fixing the top of the risers, and the plate at the bottom i thought it would be as strong as having them on straight to the base plate.

carriage height in Z (top to bottom of the moving body) is very short and quite a bit less than the overhang of the spindle. Yes I will increase this to 150 - 200mm from the 100 it is now

Also the depth in Y from the spindle to the column is fairly limited. Once you have a vise in there, you will lose some of that, reducing it even further. - I tried to space it so the axis of spindle was relatively central to the limits of the Y travel, see below. Would it be more useful further out. Lack of experience on my part to know this


Spindle axis to table edge - 23.5mm


Spindle axis to table edge - 10.42mm
