Any blue prints on a profile machine out-there?

I am considering building a profile machine. I seen the Australian version and it does not look that complicated. Does anyone have ideas on where to find plans for one. I read a lot of the postings in the archives, but with no luck. Any input on such apparatus be positive or negative is welcome.

Thank you all in advance…
