Avid Nose Wheel Steering Push Pull Tube in Avidfoxflyers General Hangar wypaul Posted Tuesday at 12:17 AM When I was building the F7a I found some weld nuts to make the pushrods and then used some 10-32 long set screws to make those pushrods. I tried to find where I bought the weld nuts but I just don't recall. I do have a few of the long grade 8 set screws that I can send you if you find the weld nuts. My guess is that the original tube that you have had cap screws welded onto the end of the tube before it was chromed. That wil make them prone to break and don't recommend that method. Also there is a modified setup with better geometry that should be much better on the Yahoo Avid flier site in the files section there is a drawing and somewhere there is a more complete set of instructions for this mod but I am not sure where but someone on this site my have them.
