Glad I asked about the I beam, seems everyone experience counters my intuition because I thaught I beams were very ridged and strong. I have some square 2 inch 250 wall maybe I will try and fit that in instead.
To all, I realize that I do not know what I am doing, I just have the basic skills to accomplish it. I have been making things from metal for quite some time and casting repair parts, although not on the scale needed for these machines.
I really appreciate the advice and frankness.
thanks
Jim

I am thinking of using a I beam for the bed and wanted to know do I need to have the bed and ways scraped beore making the patterns for head stock and carriage? seems to me the casting would be needing so much work that I could just fit everthing up, then do the casting and scraping.
