Planing Southbend Lathe Bed

This video is of the planing of a Southbend 10“ long bed that I did this past summer. As I recall the bed was 48“ long. It was quite worn. There was also an odd bend at the headstock wherein at the end of the bed the last 10“ slopped upward about “ above the plane of the bed, and was also bent slightly toward the back as well. I have no idea why. The entire bed also had a slight “S“ shape to it in the horizontal plane as can be seen in cutting the backside of the headstock Vee and the final cutting of the back side. However this was so small that it does not raise questions for me. By the time the video begins the base had already been planed. The bed is long and thus has support pads mid-way in its length. Since these pads are needed for support while planing, the base must be machined flat to insure that all pads are in the same plane. Planing of the base for a lathe with a center foot requires that the tops of the Vees be planed first while the bed is
