    Question Building an X-stand for 65# rocket. What diameter PVC?

    For a big rocket that might weight up to 65 pounds, depending on motor selection, what size PVC should I use to build a ground stand (X stand or Y stand) that will support its weight without collapsing? I'm figuring someone has already done this....

    Thanks.

    And lighter weight, no doubt!

    Definitely. Not to mention it will look prettier than the stand I made in 5 minutes because I needed something to hold the fin can while I did T2T

    Ha! I actually want it to be tall enough that it is easy to screw in my shear pins without bending over too much. If it requires too much bending, I will have to get Matt to put my pins in.

    Right now I am thinking maybe 2" pipe. But I could save a lot of money if 1.5" or 1.75" will do.

    But then it will roll off when the wind blows. I am using saw horses in the basement, but it's the same thing. I need something to hold it still.

    I have seen some of our guys using camping stools. Looks like a great way to hold the rocket to me.

    I use 1" pvc. Holds my in-progress rocket that will weigh 50+ lbs with not issues. The legs are each 12".
    Put it on a folding table and use rubber tape on the bottom. . No sliding.

    I've been eyeing these, though for the utility. Use them as seats when not at a launch. I love the pouch on them. Can never have enough places to store baubels during launch day.

    Probably cheaper than PVC fittings and they have other uses.

    Not a bad idea. Definitely cheaper. But still only 16" high. I'm still thinking about this....

    I used 3/4" for my stands. I made two U shaped about 28" tall, put them together and used a 1/4-20 piece of threaded rod with two lock nut and a spacer between so the foam would still fold flat and a piece of 150 lb Dacron line on the bottom of the U to keep that from spreading and from going flat. Some foam pipe insulation on the top parts and two of them hold my 55# rocket. The part with the highest stress is the line holding the bottom pieces from spreading too far. The cheap 1/4" non-welded chain just spread apart.

    I looked at the pouch as another place to forget where I put that one thing that I really need at the moment I most need it.

    Of course. And during the season there are flags and other indicators that Packer fans live there!

    Thanks.... I don't know how elegant those are, but they work quite well and what I like best is they fold pretty flat and are easy to store. Of course if you made one U much wider then the other and put the smaller inside the wider one when you drilled the pivot holes they could be really flat, but I found it easier to make the U the same size and only have to adjust the spacer for the size of the foam.
