Just got a CAD file for the machine which shows (again) how much effort went into that design: https://drive.google.com/file/d/1BBsQbnaCueyqj4zPCH2-i788HQAx2VYj/view?usp=sharing  ðŸ¤¯

Always wanted a magnetic base drill press. I do have a full size drill press in the garage, but the mag base would be super handy. Cant wait to see more. Keep up the great videos

A combination of the two would be cool, sort or a conventional metal stand on which you could clamp a mag drill

Hi Marco. Concerning those ballscrews, 20mm is way overkill. 15mm would be simply overkill, but a solid choice. The smaller units will be easier to fit.

It seems most ball screw diameters are sized big enough to prevent whipping which is a problem for the longer length screws. A better way to do it in my opinion, is to use a ball smaller screw with a coarser pitch. That way you don't have to spin it as fast to achieve your desired axis speed. Whipping is eliminated and the inertia of the smaller screw is much less than the larger screw. A coarser screw requires greater positioning resolution obviously, so choose your motors appropriately. I really enjoy your videos. Hope this is helpful.

Why a person sold this, given amount of effort?

From step file you provided I you can see place for ballscrew you mentioned, but from the video it doesn't seems like the part machined as in step file
