I have access to a rather large plasma table. I was thinking of using it to cut out a cnc from a single sheet of 1/2 hot rolled steel and use SBR20 linear rail kit from ebay. I already have a pretty nice spindle for my MPCNC that I'll be using.

I put together a quick sketch of my idea what do y'all think? I'm worried that z movement will be roughly 23" and I'll loose 7" to the spindle mount. However this is just a quick idea I had any advice or input is welcome.
