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.
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!
Great videos man, just got into this UA-cam genre, and Amateur Rocketry myself, and it's fascinating for someone who knows organic chemistry damn well.
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.
Can you tell me more about the fate of the Chute Release? How did it fail? Did you use a rubber band or scunci (aka scrunchi)? Did the Chute Release return in reusable condition?
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.
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
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.
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.
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.

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.
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?
I’m telling you Joey it’s the way to go!
Make the JB-Wocket
If the Hot Glocket can be made so can the J.B. WEEEEEEEELD

Display it like a trophy man. Good job, and thank you for the decals they looked great.

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

If Joe Barnard can make a high power rocket from hot glue, you can definitely make one entirely from JB Weld 😂 🚀.
We talked about that on our podcast with Joe recently! It's definitely possible but I'm not sure it's worth it lol
Sick flight Braden. Great build overall. Love the pink motor and the glitter print job.
Congrats on a great flight! ... Sounds like you need to paint the rocket with JB Weld :)
So glad I found your channel. You should have a lot more subscribers.
Great videos man, just got into this UA-cam genre, and Amateur Rocketry myself, and it's fascinating for someone who knows organic chemistry damn well.
De-gassing should also help the epoxy mix be more consistent from batch to batch.
Congratulations!
Awesome flight!
I think it needs to be left "as is"
Take it along with you as a "show piece"
Congratulations on a great flight!
Great vid, and awesome flight!
Good job... It was flown art FAR. I fly my own home brew M in min diameter rockets there as well.
We need a full jb weld rocket
Dude that was awesome

Would this thing sonic boom? I heard something at 13:06 ??
Do you have a video of your twist and tape method for powering your electronics?
Can you tell me more about the fate of the Chute Release? How did it fail? Did you use a rubber band or scunci (aka scrunchi)? Did the Chute Release return in reusable condition?
Why don't they build one out of metal? Using 3mm (1/8") stainless steel? Too heavy?

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

have you thought of using JB Weld as the epoxy base for your fibreglass or carbon fibre ?
I've considered it but I'd have to test to see if thinning it enough to laminate with it is functional
@@RocketVlogs Use the slowest version and heat it, rather than adding some thinner. Assuming that JB Weld has a slow version.
@@lr21643 The standard JB Weld is the slowest version to my knowledge. However, heating epoxy up is a great way to make it cure faster 😉
How much heavier do you think JB weld is vs thickened epoxy?
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
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.
Sand all the paint off? Nah, give it a bunch of clearcoat. It will survive for at least the first 50 feet.
Cool
