Muriatic acid.jpg
12 KB,
My dad has about half a gallon of muriatic acid that my idiot brother bought because he needed some hardware to weld on but was too lazy to find non-plated.

I have been tasked to find out how to store it indefinitely.

It's currently in a glass jar but it's pretty obviously leaking, I assume from the vapor eating the gasket on the lid. What material and shape of container would be able to store this shit without it seeping out and eating everything in the garage?

Put it back in its original bottle. Keep the bottle in a well-ventilated place, away from anything which can rust or corrode.

Fuck. Don't have the bottle. Polypropylene you think?

Lamellar or Banded style armor.

consider making this out of cardboard covered in duct tape for slashing protection. Then use a huge needed and sew in some pockets for the plates.

I made a suit with aluminum can inside of cardboard then two layers of duct tape. Was very very strong vs slashing/pierce unless you had a stiletto and full bodyweight behind it.

Easy to move in too. I don't know wtf you are making.

It took about a day to make chest/arm/groin protection using larger strips. Could jump, climb and roll. Would have been sweet but obviously look goofy.

It's toast. Remove as many components as you can, scrape off any gold on what's left if you're a poorfag, and toss the shell.

Req for some thoughts on a design or design features for a wooden 3-family apartment mailbox.

I just moved into one and the current mailbox is 3 shitty plastic bins on the front porch with stickers for tenant labels. Need to upgrade that shit.

I'm also interested in incorporating a false bottom or something as a hide-a-key.

>Req for some thoughts on a design or design features for a wooden 3-family apartment mailbox.
Fun fact: in the USA, mailboxes for postal service use must meet a set of guidelines issued and maintained by the Postmaster General.
If you want to make your own mailbox, there is some rules about that:
https://www.usps.com/manage/mailboxes.htm
>>
>>1011764
Maybe just use combination locks, and you and your neighbors can just keep spare key in the respected boxes. That way no one can find the fake bottom and break in to your apartment.
>>
maybe a metal ammo or gas can, if you can find one large enough

cut a slot for mail, get a lock kit, and mount it to something secure with bolts

Do any of you guys have experience with patents?

I have an invention in my head for a new type of simple gym equipment....

Here's the thing--I don't believe in copyright, but it rips my guts apart to imagine making my product, some big mega corp steals my idea--they patent it, and then I get thrown in jail for selling something I invented first.

I fuckin hate the legal system.

You know, patent does nothing else than allows you to sue people who try to copy your donut steel. Without the legal system and your willingness to sue (or credibly threaten to sue) the infringers, patent is worthless.
>>
>>1011543
that's not why I want to do the patent, I don't care if people steal my invention, what I am worried about is if people steal my invention, patent it themselves, then sue me for using the patent that I invented.

See?

>, what I am worried about is if people steal my invention, patent it themselves, then sue me for using the patent that I invented.

patents don't work like that.

if you document your "invention" and bring it to market, what you created will be what's called "prior art"

you can not use a patent to litigate against its own prior art.

Hello,

I would like to mount my TV on the wall and put shelving (will post below) around it. I don't want it to look cheap or tacky. The counter on the left is my kitchen. The window on the right over looks the deck and beside that, out of picture, is a sliding glass door to the patio.

I like the idea of floating shelves, but I've no idea how to accomplish such. There will be heavy books and possibly some sewing machines on the shelves, so I don't think floating shelves will be sturdy enough.

Plan B was using Fasttrack style shelving, but I don't want to look like I live in a department store. I was thinking of spray painting the metal hardware a light gold (not bronze) and pair it with a more expensive warm wood, as close to teak as I can get to match my teak table. Is that a bad idea?

Does any one have any suggestions? I'd greatly appreciate it.

Thank you.

I was also thinking about incorporating a floating shelf (Ikea cupboard hack) with the same wood on top. I could really use the extra storage, but I don't want to weigh down the room. The apartment is only 500sq/ft.

Another floating cabinet style. I think I like the wood on both top and bottom. Open to suggestions. Thank you.

If you have to ask, you won't be able to make it happen unless the software to do so already exists.

i've done this using the sound card, as have others, so there is documentation for doing it that way. also, there's at least one instructables.com project using the serial port, if you still have such a thing.

offhand i dont know of any projects using USB receivers. presumably someone would have to write their own driver, which requires major skillz.

You can decode IR from a remote using arduino and the IR sensor. Costs less than 3$.

Anyone make their own shift knob?

The one in my car has broken apart, probably due to old age.
Its made of a semi-hard rubbery plastic. I've gorilla glued it together and its held up for now. But I know its going to break soon. I can feel it flexing and trying to sheer itself apart when I shift into reverse

I'm working on making a replacement one out of wood to match the rest of the trim. Working on possibly improving the design to make it more ergonomic as well.

Yeah I've made one. Take your time, and start by drilling out the hole and threading it onto the shaft to make sure the wood doesn't split.

>>1010028
I'm going to match a nut to the thread on the shaft, then embed that nut into the knob and epoxy it.

I'm changing the shape of it from the factory one aswell to suit my style of driving. It will be thicker so

The left side of the knob is going to have some belly so it will fit in my palm, while the right side will be concave to fit my bottom fingers. (The car is RHD).

My goal is to be able to shift using my wrist and fingers, without lifting my forearm off the armrest.

All I know is its reddish orange in color, pretty hard, smells bad when sanded or sawn, and doesn't carve easy.
