I would like to mount my new LMS MiniMill on threaded risers. What I'm looking for is about 2" O.D., 1" thick metal. Basically like a hockey puck. My question is, would it make any difference what metal they're made of? Since I don't have stock of my own, I'm looking at various suppliers and I can find 6061 aluminum, general purpose low-carbon steel, 1045 carbon steel, gray cast iron, and 7075-T6 aluminum. All the above choices are available in the size I want. The cast iron is especially inexpensive - I live in Arizona so rust is a minimal issue with my shop. Whatever I choose, I'll have to drill & tap four pucks in the center for 3/8-16 threads.
Which of my choices would you folks choose for ease of drilling/tapping? Iron absorbs vibration pretty well, as I understand it. Since they would be used as risers, I don't know if the dampening effect would be significant - I really don't have a vibration problem to begin with.
Thanks in advance........
