1. aerogel is expensive as fuck
2. Once aerogel absorbs water it just becomes regular gel

You can get big o' blocks of styrofoam for boat docks and do pretty much the same thing.

Plastic bottles. Some guy has done this and lives on the ocean.

they will eventually rust if you piss all over them and don't clean.

>>1175542
stainless steel rusts?

>>1175545
Yeah, it's steel with a thin coat of chromium to protect against rusting. Once that thin layer is gone, it'll rust.

I'll have £4k to spend on a new printer next month. I currently run a Flashforge Creator Pro and am looking for something that supports build volumes of at least 20x20x20, ideally 30x30x30cm. Is the Raise3D N2 Plus my only realistic option? I'm not a fan of kit printers and need an enclosed space for nylon (all metal hot end out of the box would be nice so I don't have to void the warranty immediately).

Is methacrylate a good material for a printer? sure it's an acrylic but isn't it more rigid than a lot of materials?

>So how would one going about building a jet engine?
You can't, it's complexity and materials can't be accomplished without spending hefty amounts of money.
> steam engine and a propeller?
Retarded idea, you've got to add the weight of the water to the weight of the fuel and the big burning chamber.

A pulsejet is the simplest engine I know of, not too powerful tho and a tad noisy, but runs on gas.
I think your best bet would be to use existing motors/airplaines until you can't find more replacement parts/fuel.

Thanks for saging, this thread is pretty retarded.

>So how would one going about building a jet engine?

You can't make a jet engine to the tolerances needed without precision industrial equipment. Jets in WWII (both the Nazi jets and the experimental ones other nations were tinkering with in secret) had huge amounts of issues (IE flaring out, catching fire, exploding, just plain not working) due to 1940s materials and manufacturing. Even in the 50s jets had problems.

Your best bet for caveman aircraft is as high a power-to-weight normal internal combustion engine as you can possibly go. Also note that airplanes are fucking huge. Even small, single-person craft are nearly the size of a bus.

Also alcohol has only a bit more than half the energy of avgas and can lead to other issues such as engine knocking.

Aircraft require infrastructure for constant use. In a post-apocalyptic environment you would have none of this. As they must be flown regularly to avoid deterioration, the limited fuel and maintenance resources remaining for aircraft would quickly run dry, rending the planes into sources of scrap within a few years.

im thinking of something along the lines of this and then maybe working it into something more. also it would most likely be used in an ancap society so the variables for fuel and infrastructure would be more accesible

Most stump removers are based on Potassium Nitrate. Drill some holes and put that shit in along with some water.
It's not super fast though, it will take around a month until it is rotten enough to remove it with a hoe.

The other option is to burn it. There are hundreds of videos and how-tos on this topic.

>Most stump removers are based on Potassium Nitrate.

In most places in the USA that is no longer true due to regulations for preventing meth cooking.

>>1182608
I ended up build a fire on it and having a cook out. It was okay since the nearest trees were over 200 feet away so there was never a concern about a root fire causing something else to catch on fire.

For the ones in the woods I drill a few holes and put in some chicken-of-the-woods mushroom plug spawn. Because you can't have enough chicken-of-the-woods.

>>1182608
drill the holes and stuff them with mushroom spawn

People like you are the reason i've applied for janitoring.

>>1182251
Because you really enjoyed cleaning up after I fucked you're mom?

Hey, /b/ called, they want their retard back. Would you be so kind to go?

>>1181895
No, super glue has shitty shear strength.

You'd find it easier screwing the bracket to a wooden post, then securing the post with something like grab adhesive or some sort of quick clamp if feasible

i should add, the brace is plastic, not aluminum.

>>1181901
wow, so screw into a block of wood and clamp it to the siding? it's going on a post essentially, my house has these railings on the second floor porch

REEEEEE NOT LEVEL FIIIVVVVEEEEEE.

I dunno.

>>1181726
Level 5? I apologise for my ignorance, but what do you mean?

Op, this is the result of being out of shape and trying to do manual labor for hours. Look up muscle fatigue and follow the various home remedies and consider light medication. If it doesn't get better after a few weeks then go see you pcp.

The easy home remedies:
Icy hot rubbed on stiff joints and muscles.
Take a multivitamin.
Hot bath with Epson salt (don't need the expensive dented kind).

More drastic and expensive:
Get a massage.
See a chiropractor if massage leaves the muscles looser but back joints are still stiff.

Most drastic:
See pcp and get a prescription for muscle relaxers (some chiropractors can do this)

The idea is to make a taser to zap
myself and end up with smashed potato for brain.

just take apart one of these disposable cameras from Fuji or Kodak. they generate aprox 250Vdc for operating the flash from one 1.5V AA battery. no doubt someone's made a how-to guide somewhere on Youtube or Instructables. cost is like $6 new or $1 at the thrift store.

>Negative pin of diode should go to the collector of the transistor.

lol

Start by CNC milling all the parts out, then putting them together.

Do you mean 3/16 in a single pass?

If so you are insane and should do some research first

saved you $4000 and some change.

I know it's gotta be simple but I'm at a loss here...

It's not designed to be disassembled. Those indents are pressed into the hub the knob is attached to. It's chinese pot metal garbage. Just twist really hard.

My favorite tool is the hammer

>>1180636
Your case and HSF are shit.Switch to a i5 skylake and go with a noctua heat sink and corsair 600q instead.

Also you're going to want an HDD if you' want a gaymen rig.

>>1180329
use it to get into your hotel room for the hooker project

This (insert long pause here) will cut.

I wonder how many of the aluminum can forge /diy/kes are trying their hands at bladesmithing now.

There's always casual sex. You could have casual sex with women you'd meet on the internet or on campus. You could have sex with them outside if you'd like since you seem into that sort of thing.

>>1179397
you could do a string of brutal murders.
you could leave letters in code and phone the police anonymously after each murder to ask them a riddle
