Hi Kong,
How large is the spindle on your lathe head?
I purchased a 3-jaw chuck to fit my lathe. I also purchased the cross slide vise that I bolted to my lathe bed. That acts as my tool holder.
My lathe has a 1", 8 threads/inch spindle. That allows me to take light cuts in aluminum. Steel is more of a problem since I have to take even lighter cuts and the vise is hard to adjust in such fine incriments. Also the spindle flexes which leads to vibration.
What are you trying to mill out of copper? Are you trying to engrave it? Or are you trying to cut shapes? How thick?
