In this video I show you the plans and CAD-drawings from my homemade milling spindle which can also be downloaded
I have been searching for a design like this for some time. This could be adapted for use as a milling spindle for a small lathe. I have been using a Unimat cartridge spindle but it is limited in vertical travel to about 1”. I want to at least double that to allow for deeper drilling.

Nice work Steve.
I too have very basic bench drill (RECORD) which I inherited, I have made a few mods for milling non ferrous metals with an old XY table. The main limitations were the Jacobs taper chuck mounting and the flimsy tubular column. I replaced the column with a solid one and after removing the chuck drilled and reamed the end to take ¼ end mills. The next problem was being able to lower the head down to the table for rigidity, easily fixed by cutting away part of the belt guard and fitting a stop collar to the column. Then a fine feed was made for the quill together with a quill lock.
I mainly use it for coordinate drilling but a decent quill as your design would improve matters and thanks for the drawings.
