I am considering checking out a Felder 12" unit listed as a CF731 which appears to be a jointer-planer which has been separated from the saw/shaper half of a full-on combination machine. Not much detail on it, including the age. I assume it's a straight-knife head. The control box looks rather complicated which makes me wonder if it is a three phase machine equipped with some type of phase converter. Can anyone fill me in on it? https://nh.craigslist.org/tls/d/conw...647307329.html
