Not joking, we used to pull condoms over our heads until the rib was just under your nose, then we'd inflate the condom with our nose - some of them used to end up a mater long. Try inflating and deflating the condoms a few times before you put them on, might make things a bit easier.
@nebulus3919 at 17:13 its 25 deg C 12:03 pm and 4 805. I didn't know what 4 805 meant and just as I was about to search it on google I realised who fucking cares and got another beer instead.
I really really appreciate the focus on safety - it’s often technically interesting too. The bit about different size fiberglass particles is a very neat point. Unrelated: I laughed so hard every time the robot dub started
I bet you’re who the Walgreens cashiers talk about during their breaks. “That guy was in the store again today and bought his THIRD 10-pack of Titan 3XL’s this week”
XXXL - Joe, you're packing some serious rocket science! 😂 Haven't laughed this hard since I learned the moon isn't made of cheese! Thanks for the size-ably hilarious moment! ❤🤣🤣🤣🤣
My very favorite warning sign is "Warning: This machine will kill you and it will hurt the whole time you are dying." Keep on talking about safety. And flared bases.
NEVER stop talking about safety, as you said it's easy to forget and/or become complacent. Glad to see you are so safety conscious unlike myself, and it could easily save a life or a lot of pain. Also love the videos.
@15:23 is by far my favourite line: "I'm just a dude putting condoms on mildly phallic shape in the name of cooking meat by going to mach 3". If there was a RUclips greatest ever lines, I'd submit yours... I'd PAY to submit yours.. 🤣😂
I am so glad that the most prominent amateur rocketeer on the internet always emphasizes safety and employs generally accepted best practices in his projects. Unlike some other people who have made popular rocketry videos.
its important if ur the one doing it, if ur only watching and never thinking of every doing the same or using the tool, safety isnt something that u will gain from... tho it is super important if u end up doing it
ESPECIALLY in the RUclips science space people are so cavalier about safety. Very refreshing to watch project videos without constantly being concerned for their safety.
I love the end-credit message, it’s something that I’ve slowly come to realise myself as well. I’m at my happiest when I’m making something, thank you for keeping that in :) I also love the outro of that one YT who’s currently trying to build a Marble Clock that shows seconds, he always ends it with “go out and make something!” X3
I love how much respect you give to the lathe. Very very happy to see safety being taken seriously; especially with the heavy handed use of respirators as well. I've seen too many bloodied meat bags on the dark side of the internet to ever be lax around a lathe again. You don't even want to know what they're capable of.
24:06 things that will be used to hold a mic: A hammer A pair of scissors A wrench A chunk of wood Things that will be used to hold a vacuum over a lathe to suck up fiberglass dust: The mic stand
24:28 Hey! Never quit talking about safety! This is one of my favourite parts of the channel. When we stop talking about it, we start getting lazy. When we get lazy, we get hurt.
8:36 Put the piece of aluminum ABOVE THE LEG of the table, preferably at a CORNER leg. THEN bang the whatever on it. This will transfer the force directly to the floor, giving it a lot more stopping power, AND (very important in a, ahem, makerspace with other people in it) it will make significantly less noise banging on the table.
Please don't stop the safety warnings/precautions. I think they are an integral part of the process, and seeing what goes into it is as informative and entertaining as the rest of the build.
Dude this video is gold. You can't make this stuff up and the fact that you're kind a tip toeing around the elephant in the room since being on RUclips makes it even funnier. Truly sad though for the demonetization, but... thats RUclips for you
Love the humour! You bring a very personable approach to a highly technical subject matter, it fascinates me to see what's involved to make it to the launch pad!
You are a CHAMPION for talking so much and prominently about safety, honestly. It's so easy to skip it, and to leave it out of the video, but I think this is the best part of your videos 🙏
When you said N5800 my jaw dropped. When showing the judge at IREC our 4'' Min-D N5800 rocket he said "Many have tried". Our fins ending up getting torn off our rocket after we hit 30 gs and it was quite a sad day. If anyone can do it, it is definitely you.
@@kitsandham7001 When the N5800 was first released, the manufacturer ran a contest to break the N altitude record with it. Lots of people tried and almost all of them failed. The current record with the motor is almost 20km. Joe is aiming a lot lower and building a significantly heavier and stronger rocket.
Just... make sure it's the unlubricated ones. We use them to seal up bits of an engine when going through deeper water, but the last thing you want is to cover your electircal connections and airbox seals in... that goo.
I didn't know your channel so this is the first video by you that I'm watching, but this didn't feel like 30 minutes at all. Master class of storytelling and comedy, albeit the material helped a bit, but you presented it perfectly. And I love the serious bits about workspace safety and mental health as well! Have my well deseverd sub.
I LOVE that you talk so much about safety. There are so many makers out there doing incredibly dangerous things that set a really bad example. Thank you for being a better example.
The number of other RUclips personalities I've seen lately wearing Pizzamas shirts is pleasantly high. Also the little plug at the end about building stuff being a mental health boost is so legit. I got laid off from work for a few months during lock down and I built and arcade cabinet. It was seriously one of the only things that kept me sane.
On the topic of dust collection you might want to consider adding a woodworking dust collector to your shop. They pull a high volume of air at low pressure and do a much better job getting the fine particles. The shop vacs run high pressure low volume, they of course get some fine stuff but tend to do better with bigger chunks.
so. Your novel latex mold release device is in fact made on a manderal mold that is very simular to the manderal mold you used, just with straight walls and made of a conductive material to test for tightness against viral contamination and microscopic deoxyribonucleic acid delivery devices. As your not concerned with virual contaimation nor deoxyribonucleic acid delivery devices in your application you could instead just paint some latex on the manderal, invert it to allow excess to drip off and smooth out then allow to dry. apply air inbetween the manderal and latex bladder to flex the novel latex mold release after the epoxy in the fiberglass has cured.
@@AKAtheA 2 reasons; 1, to allow the manderal to fully release from the diffrence in elasticity. (IE it can take a lot more then epoxy's maximum allowable elastic deformation to get it to mechanically release thats why its such a good product for cementing fiberglass together) 2, to allow advice to be useful for all simular applications. Your epoxy/fiberglass composite might streach up to 2% but not all will, some will only allow a fraction of that, and some additives allow the epoxy/fiber composite to streach up to 7%.
This is the funniest video I've seen all week. about died when the loose plastic bits fell out of the infill. Quite possibly the funniest rocket building video on the internet
21:49 the tool you clearly need is a SLIDE HAMMER. Check with Harbor Freight, they're pretty cheap and do come in handy. I would say the same of their hydraulic jack / puller kit.
Use wax, I am a beekeeper so I use beeswax, but a low melting paraffin wax is rumoured to be even more effective for smothing and mild release. Dip the shape in wax a few times (3-10) before layering on the composite, and afterwards melt it out in an oven at about 70°C. Works like a charm. The jokes you can make about it are worse though, I've been thinking about it a long time, my success has only been waxing so far, but I have nor really found a pun that is the bee`s knees so far.
Please keep hammering the safety stuff. Even though I'll never build a rocket and probably won't ever have half the tools you have, it's really useful to keep the brain aware of risks and mitigation strategies. I've gotten quite a few good idea from your videos too! I've also watched enough videos of machinery accidents to know it's 100% not what you want to happen.
Honestly, never apologize for emphasizing safety the way you do. The emphasis on it is severely lacking in most content in general these days, and it can lead to people thinking these pieces of equipment aren't as dangerous as they potentially can be. Never stop reminding us all about that importance! It could be the difference between having all your fingers, your vision, or your life! Keep up the amazing work!
Spends thousands and thousands of dollars on rocket components, cameras, electronics, and materials. Absolutely REFUSES to just buy a new jug of resin. Edit: *sigh of relief* I was wrong, he got new epoxy.
Joe, I have survived my entire adult life by constantly "building things" to stave off the emotional void. I'm 61, and this is how I've lived since I was perhaps 10 years old. The down-side is that when I'm NOT building something, or what I build doesn't work out, my mood is much darker. I wonder how many other "makers" out there have the same kind of thing?
Honestly I was surprised to not hear a joke about how sometimes feeling proud about how the things you built turned out is antithetical to always using condoms.
People who haven't watched this video have no idea what they're missing out on: Innovation in various mold release techniques including those which require copious amounts of lube and thin latex tubular film. FYI, oil-based lubes will typically weaken these tubular latex mold barrier devices.
As an aerospace engineer specializing in composites: The mold sticking is a multi faceted problem. Adding lube of course lowers the friction between the mold and the part, which of course helps, however, the issue at hand is nonetheless that the part shrinks during curing. You could try using PETG or PET for the mold, that would lessen the bonding of the epoxy to the mold, because of PETG and PET surface properties. A slight draft angle on the entire rocket nose cone would also aid in releasing it. I would have made a multi part mold in PETG/PET and a slight draft angle. Adding a vacuum during curing, and shifting to vacuum infusion really helps with the parts quality.
There's also one more mold release technology in the artistry of 3D printing things that you don't want to have layers for whatever reasons. Silicone spray. Basicly it does the same as the Titan 3XL mold releaser but instead of being pre-made into the shape of a nosecone, it's in a spray can and you can spray it on the mold. And no, do not use the silicone spray instead of Titan 3XL for storing liquids, it doesn't work and while you can get food safe silicone spray, it's not clean enough and it just doesn't work in that.
This episode should have been sponsored by Starship Adult Novelties. Many opportunities were missed. Could have been the greatest April 1st video of all time.
Don't feel bad about talking about safety. More youtubers need to do that and talking about safety really shows the audience how dangerous things can be when you manufacture space parts. Safety procedures are part of the journey.
A lathe accident killed the boyfriend (adult, in his twenties) of a relative over thirty years ago, he was found by his father. His clothing got caught, causing head smashing into something. I still remember. Those machines are no joke.
You could have tried compressed air from the base to demould, the 3D print should be porous enough for the air to separate the interface to the fiberglass.
Practice nosecone did its job. Thanks for preventing me from doing something like this. We polish molds to a glassy finish and apply several layers of paste wax (with a half hour after buffing to harden before applying the next coat of wax). With flatter parts, we make the mold run long, so you can put two layers of painter's tape at the lip of the mold. When its time to release the part, you can pry the tape apart and the edge of the part and mold usually start to separate at that point. Clear coat paint can make a part smooth without having to sand down to the thousands (grit size), but once you have the surface roughly smooth, it doesn't take that long with each grit before its ready for polish without clear coating it. For tubular parts like your nosecone, they can be molded in two halves and glued together, but for high performance requiring lightness and strength, a meltable core is cast. Take your 3-D printed nosecone and use mold release, then pour a silicone rubber mold, then use that mold to cast a meltable mandrel out of wax or pot metal. Soak in hot water or bake to melt away the meltable mandrel after laying up your part over it.
I think you are right to worry about the particulates. My father worked with similar materials. He died of particulate induced respiratory cancer 2 years ago. On a brighter note, I love the experimental approach. Good enough for Space-X
For your mill, when it comes to choosing wheels or not you might be able to have your cake and eat it too by using “retractable caster wheels” which can be permanently mounted (screw on or welded) or a quick release version is available which leaves a low profile mounting plate on the mill itself once the wheels come off
They also make ones that the casters flip off to the side leaving it sitting on the leveling feet. the rollup stairs they use at the big box home improvement stores work the same way.

Does the censoring algorithm have a limit on the number of times you can say "condom" and "lube"? Because whatever it is, you probably exceeded it.
Not joking, we used to pull condoms over our heads until the rib was just under your nose, then we'd inflate the condom with our nose - some of them used to end up a mater long. Try inflating and deflating the condoms a few times before you put them on, might make things a bit easier.

I would have made a multi part mold in PETG/PET and a slight draft angle. Adding a vacuum during curing, and shifting to vacuum infusion really helps with the parts quality.
3:24 "It should not be this deep red color and yet it seems to work fine" also applies to Rodinal black and white film developer.
Joe, cover the lathe ways when sanding anything. You don't want the fiberglass dust getting caught between the two sliding surfaces
There's also one more mold release technology in the artistry of 3D printing things that you don't want to have layers for whatever reasons. Silicone spray. Basicly it does the same as the Titan 3XL mold releaser but instead of being pre-made into the shape of a nosecone, it's in a spray can and you can spray it on the mold.
And no, do not use the silicone spray instead of Titan 3XL for storing liquids, it doesn't work and while you can get food safe silicone spray, it's not clean enough and it just doesn't work in that.
This episode should have been sponsored by Starship Adult Novelties. Many opportunities were missed. Could have been the greatest April 1st video of all time.
19:39 it seems like 5 condoms we’re infact not enough condoms 😂
7:18 has to be the best line ever on this channel, well played! 😂
I don’t believe for a second that you’re sorry for that sentence.
* sigh *
ok, let's open the comments
At 19:54 you can see his last shred of integrity leaving his body
Don't feel bad about talking about safety. More youtubers need to do that and talking about safety really shows the audience how dangerous things can be when you manufacture space parts. Safety procedures are part of the journey.
After heating it in the oven worked so well, why not just proceed with that as the plan for mandrel removal?
because it destroyed the mandrel, it was no longer in the shape of a mandrel after being removed
@ I wasn't aware the mandrel was supposed to be multi use
can't decide whether to say "oh joe" or "joe no"
It’s joever
@BrainiacManiac142 😔
joe no u did not
He’s a professional
7:18 no way I just heard that sentence
Don't apologize for stressing about safety. Safety is planned, not an accident.
Decreased diligance december
A lathe accident killed the boyfriend (adult, in his twenties) of a relative over thirty years ago, he was found by his father. His clothing got caught, causing head smashing into something. I still remember. Those machines are no joke.
Was it the first time the boyfriend got lathe?
@@bobweiram6321 dude. you might wanna delete that completely out of place joke. not cool.
1:16 this needs a pixelation
You’re videos have always been good, but I’ve noticed a very sharp increase in my enjoyment of them recently. Keep up the good work!
Imagine checking out with those “I need these to cook steak in a rocket”
1:24 well well well, looks like someone have done this before.
You could have tried compressed air from the base to demould, the 3D print should be porous enough for the air to separate the interface to the fiberglass.
The amount of innuendos is off the charts
Practice nosecone did its job. Thanks for preventing me from doing something like this.
We polish molds to a glassy finish and apply several layers of paste wax (with a half hour after buffing to harden before applying the next coat of wax). With flatter parts, we make the mold run long, so you can put two layers of painter's tape at the lip of the mold. When its time to release the part, you can pry the tape apart and the edge of the part and mold usually start to separate at that point. Clear coat paint can make a part smooth without having to sand down to the thousands (grit size), but once you have the surface roughly smooth, it doesn't take that long with each grit before its ready for polish without clear coating it. For tubular parts like your nosecone, they can be molded in two halves and glued together, but for high performance requiring lightness and strength, a meltable core is cast. Take your 3-D printed nosecone and use mold release, then pour a silicone rubber mold, then use that mold to cast a meltable mandrel out of wax or pot metal. Soak in hot water or bake to melt away the meltable mandrel after laying up your part over it.
I thought this video was going to be cringy but it was hilarious
The amount of T-shirt ideas with the various "scientific" phrases and quotes here are ENDLESS!
Melt it out? Use water-soluble filament and soak it in water. Ah, there yo go. Welcome to the glass transition temperature of thermoplastics
I am not sure I can be on my best behaviour while watching this video.
I think you are right to worry about the particulates. My father worked with similar materials. He died of particulate induced respiratory cancer 2 years ago.
On a brighter note, I love the experimental approach. Good enough for Space-X
For your mill, when it comes to choosing wheels or not you might be able to have your cake and eat it too by using “retractable caster wheels” which can be permanently mounted (screw on or welded) or a quick release version is available which leaves a low profile mounting plate on the mill itself once the wheels come off
They also make ones that the casters flip off to the side leaving it sitting on the leveling feet. the rollup stairs they use at the big box home improvement stores work the same way.
