Larry a good set of plans is more important than a jig. You can build a nice straight frame without a jig. Takes patience and a lot of measuring. A good jig would be nice if you are going to build more than one or two. Keep in mind that when you weld it will pull the tubing all over the place. This will happen with a jig . You have to learn tweek thing as you go to keep things straight.

I build thing from others plans. Most plans have problems. From what I have seen there are no cobra chassis plans that don't have problems with the numbers or missing numbers. They just don't add up.

If you could find a set of plans with good numbers it would easy to build accurately with no jig.
