DIY Milling Machine Build [Based on Bridgeport]. Part 1: Quill box and spindle assembly

New project , new challenge!
I don't have any drillpress in my workshop, corded drill have huge limits. One day I decided to find machine that will fit to my needs. After months spent on searching I tought, Why only drillpress? Milling ability could be a nice thing. I felt in love in Bridgeport mills design. Those machines are almost impossible to buy in Poland in used condition. So why don't build simmilar by myself?
Couple hours in front of PC screen , moments of waiting for packs from China and here we are. New series starts just now!
Due to extremely high steel prices again I'm forced to use scrap steel, this causes some delay in build. I hope I will finish basic part in next two months.
