Since I don't have a mill, but I do have a milling attachment for my lathe....

Looks like a carbide insert boring bar makes a pretty good milling face cutter. First time trying this. This might not be news to the real machinists out there, but I'm not a real machinist by a long shot.

View attachment 175317

a small tilting angle vice would be worth buying as well. Build a bracket to mount it on your tool holder And you can now drill and tap more things than you can imagine. I tap threads over using my mill quite often I put the gears in neutral and spin the chuck by hand gives me rigidity leverage control and feel that really improves tapping threads.

I think I may have the capability to tilt and rotate the vice with the bits I've got. The whole milling attachment can rotate 360 degrees at the base and the vice and mount plate assembly can also rotate. Would this cover what you're thinking ?

you will have to tinker with it. I have a big Mill so I really don’t use my tilting vices but one of them is made to fit the lathes ways and it allows a variety of options. The previous owner fabricated scaled down train parts he did multiple steps in one piece while keeping the mill open for other uses. He had it set up to use drill bit a chamfer bit and a tap on one piece in the vice. Really being able to hand turn the lathes chuck to thread is great if you need a repeatable step.
