Pretty thorough cold repair there.
Are those your Y rails then with the linear rails on the side?
BTW, you can reduce the aggro factor in the drill press and risk of breaking off the tap in the hole by using a hand tap wrench and one of these spring guides in the drill chuck to keep it in line.
Depending on the type of tap wrench you use is whether to use the pin or socket end. If you use a bar type tap wrench you’ll find a small spike or socket on the top of the tap, that’s what locates in the spring guide.
