Gorilla glue still not dry in nose cone when adding weight?

[genzod]

I glued in some bbs w gorilla glue in the nose cone on two kits, well it was 48 hours ago and iit's still not dry? It's seeing up but still sticky? I'm guessing because it's a little well of it and the nose only has a small opening in top, man I habe a launch on Saturday, any tips to speed up?

Do you have high humidity there? If not, add a tiny bit of water to the mix to get the cure going. Gorilla is water activated. If all else fails, fill the rest of the space with epoxy 2-part foam that WILL cure and hold the glob where it's supposed to stay.

Gorilla glue requires moisture in order to cure. Sealed up inside a nosecone, it's not getting any, and will take a long time to fully cure.

Another problem I had with the stuff is that if you apply too much, it will never fully cure.

At least, not in this lifetime -- same problem, moisture can't get to it. Aerosol expanding foam has the same issue.

i wet the bbs first ,should i add a few drops of water to it ?

I think the only way it will cure is to open a hole in the shouder and after dripping a bit of water, position a fan to blow down into the nosecone. Like Kevin said Gorilla glue, like construction spray foam should never be used in a confined space like that, they both need serious air exposure.

lol,a ton of people said to use gorilla glue ,as epoxy wont stick to the plastic,i was advised on this site to use goriulla glue,its the only thing that works ??

The right type of epoxy works well if applied correctly I've been doing it for over a decade.

Gorilla glue can work well to provide adhesion at the edge of bulkheads that are placed in a nosecone, if there isn't too much stress applied. But in that case the edges of the bulkhead/inner nosecone face are exposed to air so they can cure.

In your case with the glue puddled at the bottom of an enclosed cavity, you have no chance. BTW, you need to be careful in who you listen to on this, or any forum.

 

[genzod]

wow, i heard from not one but a good few level 3 guys that gorilla glue was the way to go,and done in exactly that fashion , i heard of the special epoxy but it was supposedly pricey, i didnt just listen to one guy,i know of not listenening to everyone on all the forums, but when several experienced people say the same thing its usually ok, or why else even post a question on a forum

Indeed as beezwax mentioned ,add your lead or whatever ,add a few drops of water ,shake around and pour in the Gorilla Glue (make sure it the polyurathane type).The glue expands 3-4 times and encapsulates the weight and sticks to any surface, no need for sticks or dowels drilled through the NC.

Once cured ,the weight is there to stay and will not shift

 

[genzod]

these guys seemed to know what they were talking about, i hope they are right, because if i " have no shot" that will suck,if you cant get advice from experienced L3 guys why bother with the forum at all ??

Never worked for me. I have even had trouble getting Gorilla glue to cure properly on large surfaces that aren't plastic. The internal surface area of a plate a couple inches wide stayed gooey while the edges did cure. Found out about the poor joint later when I tried to put it into use. Gorilla glue is basically good for gap filling and edge/joint adherence, but not much more, at least in my estimation. Don't get me wrong, I do use Gorilla glue, but only in applications I have found to work.

Also, please, none of these posts is meant to criticize... Believe me, I made the same mistake before; it's learning or maybe better, experimenting.

Different people have different experiences, and different methods that work for them.

Sometimes it's subtleties of methods that don't come across well in written form.

As far as your problem goes, I'd probably mist it with some water -- a puddle isn't going to help you, but dry isn't helping, either.

thanks dude,i misted w a spray bottle, who knows we'll see what happens,im sure it will eventually dry,may hit it w a blow dryer

A blow dryer on a low heat setting may be a good option.

thanks dixon,no offense taken , and i do fear you may be right,probobaly why im pissed,lol

 

[ckreef]

If I read this correctly the puddle is in the very tip of the NC. I might try drilling a few (3-4) small holes 1/16" - 1/8" in the NC where the puddle is and dripping a drop or two of water into each hole. As the glue expands and sets it will come out the holes. You will then have to cut off/sand off the glue expanding out the hole.

I used Gorilla Glue once on a RC project --- I will never use it again --- there are just too many other glues/methods that seem to work better.

JMHO

 

[blackjack2564]

I've been doing this a looooong time.

I use 2 part expanding foam to encapsulate and lock in NC weight. Never, ever, ever fails! It can't move or go anywhere!

Not the crap that comes in a can like whip cream. The 2 bottle stuff PML, Wildman,etc. sells.

You could mix up a bit. pour it right on top of your mess and be done with it.

Thing overlooked when getting advice on forum. Someone does it, they may live where high humidity...works fine.

You may live where very low humidity..... no workie fine. There are always external factors to most advice given, that may not show up in a post or the poster is not even aware off or forget to mention.

 

[luke strawwalker]

Yep, or do it in stages... dump a little in, let it foam up and cure, dump a little more, let that foam up and cure, repeat as necessary...

Later! OL JR

 

[Hogan3276]

I agree with above. 2 part foam is the only way to go...

If you have a local Hobby Lobby you can get it there too. They stock it in the Art section.

Wow you've got a lot of brass. You've started over twenty threads in the last three months asking for help on various little build steps and now you're "pissed" at the folks who've taken the time to try and help you? This is now your FOURTH thread asking specifically about nose weight. Let's review:

Folks here are very generous and don't mind hand-holding, it's the ingratitude that gets to people. You're having some trouble now, it's not working, what's the point of asking advice here if people don't know what they're talking about, this sucks I'm pissed? Really? It sounds like your gorilla glue is not setting up. It needs water to cure properly. Maybe you should have cut a hole in the shoulder of the nose cone so you could mist it just like I described back in January:

https://www.rocketryforum.com/showt...ht-to-4-quot-diameter-kit&p=460315#post460315

The problem isn't that this method will not work, it works very well. The problem is you ask for advice but don't listen.

 

[beezwax]

And for the record you were never told that epoxy would not work or that Gorilla Glue was the only answer. I told you that it was my personal preference in plastic nose cones, in my experience it has been the only thing that really sticks them. Epoxy works but you will find that many folks here also recommend drilling and adding retaining pins, because it doesn't bond that well to plastic nose cones. You also have to be careful with epoxy because it can heat up enough during the cure to actually warp the plastic. Two part foam is a great way to lock in nose weight, unless you want to have that space available for trackers, altimeters, etc. You can hollow out or mold for voids in the foam but that's a bit more work. There are pros and cons to all of them, but all of these methods were mentioned on your threads, and you were further advised to search the forum for additional threads as there have been many in the past with many good tips. So to suggest that you were led astray or told there was only one way to do it is simply not true. Don't ask questions if you're not going to listen to the answers.

 

[o1d_dude]

I have no dog in this fight but I do have a friend who does the same thing with all the questions and disregarded answers.

He knows he does this and refers to himself as an "askhole". LOL!

 

[DizWolf]

I've been following along for multiple threads and such. I have a few thoughts.

First off questions are good. When one person asks, we all learn, and all think.

Forums are a place to get ideas. Not directions. I've learned more here than I could ever imagine when I pushed the button on that first A8-3. But from all of it, it was always a journey.

Ask a question, discuss the replies. Think and think and think. You can get advice all day long, from experienced, smart people. But they're not sitting there, and they're not building your rocket. Ultimately, You're building the rocket, and responsibility for whatever happens to it falls on you. You decide what to do, in what order and why. There's nothing to be upset about, or pissed at. It's all learning.

Oh, and when doing something for the first time....never ever ever work on a deadline.

 

[AZ_Ron]

Like several other folks in this thread, I've no dog in the hunt either, but, as most everyone else, I'll toss in my $.02.
I LOVE epoxy, 2-part foam, and Gorilla glue. They ALL have their uses.
I built my L3 project (16" Diablo, flown on an 'N-2800') using nothing but Gorilla Glue, with the exception of the fiberglass strip used to join
the slot down the coupler. The Aluminum honeycomb/ply composite fins, coupler to airframe, etc was all done with GG. Fantastic stuff, but
it's NOT designed for large volume. It's designed to be applied and pressed/clamped, as it expands, it forces itself into cracks, crevices, pits, etc
and is incredibly strong. After the Diablo was built, I used 2-part foam and filled the booster, locking the fins in place, essentially making the
aft airframe, coupler and fins all one piece.

On other builds, I'm a big fan of cutting off the bottom of the NC, and attaching a leash to the tip, along with a bit of noseweight. I've used
both epoxy, and 2-part foam. If I'm striving for the most usable space, I'll use the Epoxy, just regular 15-30 minute epoxy, not the 'special'
type, (Whatever that is). I've NEVER had it come loose. For prep, (I usually do this on 4" NC's), I put a sanding drum on my dremel, turn it on
low, and then dangling it by the cord, lower it into the nosecone, then bob the dremel up and down, scuffing the living heck out of the bottom
2-3 inches (Actually the tip, but it's upside down!). Once that down, I blow all the fuzzies out, and then give it a very thorough cleaning with
either acetone or lacquer thinner, then add my leash, lead pellets, etc, and epoxy them in.

I'm not an expert by any stretch, but I learned a lot of what I know from some of the 'legends' of HPR, and to be honest, Common Sense
will get you a LONG way!!

(Anyone else think that these days, 'Common Sense' is an oxymoron??? )

Aren`t 99% of fatalities and accidents due to human error ? :wink:

Like anything else in life ,it`s a learning curve.Hell if it worked the first time `round everytime, life would be a bore !

I use plenty of techniques to hold weight into NCs ,most time just figuring it out myself ,trial and error (I like it that way ,keeps the gray matter firm and juicy) ,but I have never had a problem with polyurethane glue foaming up and setting.

Hope it works out for you !

Beeswax, wow you got it wrong, I agreed w u on the gorilla glue, I was defending you, I said I was passed not at any one but at the fact that perhaps he was right, and I wrote thanks and no offense, wow I agreed w your way of doing it, it took a little longer to dry, was just getting ready to post that is is cured, I never said I was passed at anyone on here, I said no offense and that I appreciated the help, you way read into it, I was told that regular epoxy wouldn't work, and others suggested gorilla glue even not on this page, all I was saying g was the the one guy acted as if I just blindly listened to one person, sorry I asked a few questions about my little tiny builds

 

[genzod]

Wow beeswax, did you even read my replies, I did mist the bbs before I glued them, like you said, show me where I said I was passed or ungrateful to the people here, I said I was passed, At Myself because Ifeared the guy was RRight and it may not work, you really need to read the whole thing, I would never get passed at anyone on here, jesus

Always good to get a variety of opinions no matter what it is you're doing... rocketry or otherwise...

BUT, remember that just because an idea is popular or held by a large group of people DOES NOT make it necessarily correct, nor does the fact that only one person gives you good or correct information invalidate it because it only came from one person... Sorta like the Nazi's... they all thought alike, but they all thought WRONG!

It basically comes down to "who do you trust" to know what they're talking about, and "does it pass the smell test?" (IE will this actually work??)

Later and good luck! OL JR
