Just saw this just today, they've supposedly been out for about a year or so. Neat idea IMO. A lot of second op work on the end of long parts i s done with large heavy angle plates, indicated stop bars, and C-clamps. T his is a much cleaner (and quicker), setup for the right sized parts. Obvi ously you could clamp spacers under the SideWinder to support shorter parts .
I apologize if this has been covered before. I did a topic search on S ideWinder first and didn't see anything.
It's a pretty spicy meatball at $599. I wonder when we can expect a Cheap Chinese Knock-Off, eh Jon? LOL
