The great advantage of boring in the lathe is getting the OD and ID concentric.
Why not make a boring bar? The picture of the ones attached are simple steel rods with a cross hole, to take the cutting tool, and a threaded axial hole to fix it. The cutting tools are ground from broken reduced shank carbide PCB bits.
The smallest one shown here is 5mm Diameter, used to cut the 2" deep, 5/16" ID, LH acme thread for my steady rest support arms.
