At some point I want to try my hand at some ceramic parts. Macor is machinable, but I don't know where you can buy it cheap enough.
You mention getting a Tormach for machining round parts? Most on the forum will probably ask which Tormach are you thinking about getting? Also remember round parts may be easier to make on a lathe. After I got my 770 it was probably less then a month later I had to order a Grizzly lathe as some of my jobs are simply easier faster on the lathe.
