    Love this so much - I still think the next logical step is to roll your own tubes using JB weld instead of laminating epoxy

      That is so incredibly cursed. Might not be too painful on a small size. 29mm JB weld rocket?

    Dude that's sick AF! What's even more crazy is the speed that rocket traveled, burning the paint off the nose cone with sheer air friction! Great job new subscriber here.

    If JB Weld didn't survive this, nothing else would have either. I used it for my last two rockets including a 54mm minimum diameter kit and a 2.6" Pike that flew an L805 on its maiden flight. When I was a teen in '86, I used it to repair a cracked bell housing on my Thunderbird and she just kept right on a-truckin'. Also, you kids need to get off my goddamn lawn.

    You could use that rocket with the same motor as a booster attached to a sustainer with a long-burn motor like the Aerotech M685W-PS with an 11.3 second burn time. Maybe it'll touch Mach 2.5 and hit 50K feet? It would be another great test of the limits of JB Weld.

    • @RocketVlogs

      Using the booster with the glued in coupler might present some issues, but it could definitely be done. Maybe some day

    You're a brave soul for using the chute release but hey man it worked and congrats! I had a brand new JL chute release sit in my gear box for years, and after seeing soooo many others fail with it I ended up gifting it to my local club for fund raising. My 1st min dia just showed up from Tim, so I need to figure out the whole chute deploy without a release. Awesome flight Braden!

    If Joe Barnard can make a high power rocket from hot glue, you can definitely make one entirely from JB Weld 😂 🚀.

    Convert it to a booster and stage it with a min-diameter 54mm 🙂. With a longer burn booster and a long-burn K in the sustainer, I bet you could push 40k.

  • @roboman2444
    @roboman2444 8 місяців тому

    Would mixing in glass balls/fibers or carbon fiber chop into the JB weld help the strength on the fillets? Might make it harder to get smooth, but that's what sanding and paint is for.

    • @RocketVlogs
      @RocketVlogs  8 місяців тому +1

      I have a theory that adding milled glass or chopped carbon doesn't really do anything for strength more than any other thickening agent would considering both get their strength from the weave of cloth or the wind angle when filament wound.
      I think adding anything to JB Weld would just make it unusably thick lol

    Now do an actual JB Weld rocket cast from JB Weld instead of just glued together with JB Weld.

  • @jonasclausen5755
    @jonasclausen5755 7 місяців тому

    I'm curious if you could seal in the pain effects of the first flight by doing a resin hot-coat instead of clear paint? Then you could fly it again...
    Because if you don't fly it, it isn't a rocket anymore.

    • @RocketVlogs
      @RocketVlogs  7 місяців тому

      At that point, I'd just be adding a tone of unnecessary weight on top of all the already unnecessary weight. Realistically, if I decide to fly it again, it's all getting sanded off.

      definitely heavier if not just as heavy. i just built a stretched loc kit with jb weld and its significantly heavier than it was supposed to be

    • @RocketVlogs
      @RocketVlogs  8 місяців тому +1

      Hard to day depending on epoxy and thickening agent. For example, West System thickened with Colloidal Silica is quite light, but using a fairly thick high-performance epoxy like hysol or Proline 4500 is really the optimal solution for a project like this.

  • @roboman2444

    Sand all the paint off? Nah, give it a bunch of clearcoat. It will survive for at least the first 50 feet.

    EDIT: I struck through that statement because the more I think about it, the more I realized It could very well have popped main at apogee, but I just have no idea because it was outta sight and I never saw it come down (thank god for tracking). Either way after I saw this video I'm going to use cable cutters if the design calls for something like this.
    the praise:
    1. This is of course awesome. A minimum Diameter M that is SHORTER than all the ones I've built so far, YES PLEASE!
    2. I got a lot of ideas & helpful information from this (degassing epoxy, the way you did the recovery setup, High altitude ejection charges, etc.). I could see how your recovery setup could also be used for a booster in a 2 stager, which I'm sure people have used before I just hadn't done the research yet. I want to do a small 2 stager this year (some combination of H & H or I, just to get the electronics & process down)
    3. CAN you paint a mach 2+ rocket that doesn't have it's paint do that?
    No criticisms! :)

    • @RocketVlogs
      @RocketVlogs  8 місяців тому

      I don't think it's related to the speed, necessarily. I've had this particular Chute Release do this a couple of times with some flights and work fine with others.
