Welcome Baris! You have come to the right place for help, there a number of ways to get to where you want to go with your project, any number of kits out that are on the web for the bridgeport and it's clones. It really comes down to that old question from my racing days of " how fast do you want to go = how much do you have to spend? and part of all of that is how much you can do on your own to get to where you want to go. I know this will seem kind of terrible to you but sometimes it cheaper to find a different ride to get to where you want to go. I mean by that your old Bridgy has value as a manual machine and has a wider appeal to the home machinest than a cnc mill. Cnc Bridgeports can be had cheap and that right machine is out their waiting for you, kinda like a race car that a guy you used to know had and it just wasn't fast enough for him anymore or it's broke and cost to much for him to get it back on the street again. That might be where you want to go. A restro project on that old mill and (cherry it out) you might get to where you want to go a little faster. just a few of my thoughts. And your sure to get alot more advise than just my ramblings here.
