You can do a lathe with just a straightedge. My dad and I did his Perfecto one christmas when I was 14. I am part-way through doing so on my Rivett. (and have been for a year...) A Mill is more difficult. Lathes gain accuracy from clever use of facts of geometry, whereas mills have to be set up right. Someone had ground the Rivett, but not in a wise way, they had simply ground some surfaces to where they didn't touch the saddle any more, and had not touched the dovetail. I have sorted out the saddle to bed contact, but the dovetail scraping is horrible. (no run-out groove) -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ New Year.
