The builders manual that Randy and Beej created has a great idea for a drag wire jig. Below is mine, sans paint. I did mine a little different, though. I welded a nut plate on the top of each verticle end post so that the long horizontal member could be easily removed. That way, I can install and remove the two different size guides, using only the two I am working on. One jig, both sizes. Also, if you'll notice, I used 3/4" square for the horizontal and used 1" for the guides. I then drilled a 5/16" hole in the 1" and rosette welded a piece of flat steel inside the 1" square so that it fit tight on the 3/4" square. Why did I do this the hard and time-consuming way? Because I needed the practice doing rosette welds since I never really had to do many of them.
It's mucho easier to replace a cheap piece of jig steel than it is to remake a 4130 part for the airplane.
