I got my first CNC when I was 58, and second when 64.
There is hope for you yet? or buy some ballscrews and retrofit your Bridgeport. Nothing a scrape of the ways and gibs won't fix.
Stepper motors good enough if you don't ask for stupid feed rates.
And then I built myself a 3D printer, because I could, and a control system for 12M x 5M x 2M X,Y,Z monster, someone else built.
Life begins at 60. Where in the world are you?
