These plans are freely available from Crime Scene Choppers, they outline the construction of our frame jig as shown in Ron Covell's new "Building a Chopper Chassis" video.

5 1

Few of the dimensions or material callouts are critical. The width of part #6, the frame rail fixture, is determined by the outside outside width of your lower frame rails. Typically, the inside width is 8 3/8", so the outside width is 8.375 + 2 * the diamater of your frame tubing.

Check the alignment of your parts carefully as you work, a warped jig is worse than no jig at all!
