I recently installed a power feed on the Y axis (cross feed) of my 2001 Eldorado. I have written up the installation on my Shoptask web page. I also have a section on an extended milling table, 24" instead of the standard 18", although that is a future project. Maybe after I finish my FR-F1 sniper rifle replica!
