It's been quite awhile ago that I bent track. I've only bent Gargraves and I had a large number of bends to make. I took a few minutes to make a jig from 3/4 plywood. It was easy to hold the track in place and make consistent repetitive bends and cut off the mating ends. The Gargraves had a bit of spring back. If it's used and sits around awhile the wooden ties "grab" the rails.
Bottom line is the jig is worth it if you have many bends.
