A friend of mine made me a 16" diameter by 2" thick cast iron surface plate. It was supposedly lapped "optically flat". It has a mirror bright finish. I have not checked the flatness of the plate myself.
The question I have is should I work with this plate or buy a cheap granite plate? It is for an armature home shop.
If I do use it what do I have to do for the use, care and maintenance of a cast iron surface plate?
