    The rod sees pilot forces so it is not highly stressed. I would think you could just clean it off and slip a section of opened up tubing over it, epoxied in place as a doubler. Welding it on is even better.
    To proof load the rod afterward, see FAR Sec. 23.397, which says the rod must withstand being pulled at between 100 and 167 lbs of force at the stick against the stop without deforming.

    marky244,
    AK Flyer was kind enough to scan my MK IV build manual with his high speed scanner, maybe he would borrow yours to do the same, so we can post them for everybody.

  10. nlappos added a post in a topic J3 Tail Springs   

    My thoughts:
    I suspect the best short field takeoff depends on the softness of the surface. If the field is not very soft, and therefore the wheel drag is low, then raising the tail early in the takeoff run might lead to better acceleration and shorter ground run. Also, the snap liftoff when you finally raise the nose will make you climb earlier than mushing off with max angle of attack held throughout the ground run.
    If the surface is soft, then getting the weight off the wheels earlier is probably best, so a max angle of attack ground run is best.
    In either case, the shorter tail spring is a better bet, because you get the choice of having a high angle of attack on the ground run. A long spring takes away that choice.

    republic,
    Don't worry about that wind, get back up and keep learning. I suggest getting your instructor to schedule a few dawn flights, when it is calm and also really beautiful. Once you master the aircraft, you will feel exhilarated!

    Thanks guys. I will try just grading the sage away, or using the Ratchet Rake I have to pull them out by the roots. If that doesn't work well, I'll get a Brush Hog (new toys, anyone?) 
    . I figure I'll make a 50 foot wide by 1250 long runway to start with. I'm at 5500 ft MSL, and summer temps are easily 95 degrees so I can get 9200 DA.

    Building an Airstrip
    I am starting a project to build a hangar and clear a strip in Utah, and look for some advice from you folks.
    The terrain is flat, sandy and filled with sage. See the photo below. The sage is well rooted and about 1 to 2 feet tall. 
    What is the best way to clear the strip, I have a JCB 215 backhoe, so I wonder what method would work best and easiest.
    For the hangar, I was thinking a simple 40 foot square steel building with a bifold door and concrete floor.
