You can make a "steady rest" to support the end opposite the headstock. Like the "roller rests" that manual rod wrappers have. I made one out of plywood with rubber rollers in it...and a wide base...and would lay a bag of lead shot on the base so it couldnt move. It was tricky and sort of a PITA...but I HAD to have something because the bed on my lathe was only about 20 inches or so long.
