Foregoing my earlier plan to build my own rail bender, I bought in to an Aristocraft dual rail bender (presently on sale at $119). http://www.aristocraft.com/ART11921-DUAL-RAIL-BENDER_p_422.html This massive chunk of metal arrived quickly, and I was soon at work re-curving the wobbly belly bends I had laid out the earlier month. Nice smooth action, and easily cleaned up my work on the AML Aluminum 332 track. I have no experience with other benders, but I am very happy with this tool.
