Welcome to /diy/, a place to:

Post and discuss /diy/ projects, ask questions regarding /diy/ topics and exchange ideas and techniques.

Please keep in mind:
- This is a SFW board. No fleshlights or other sex toys.
- No weapons. That goes to /k/ - Weapons. The workmanship and techniques involved in creating objects which could be used as weapons or the portion of a weapons project that involves them (e.g., forging steel for a blade, machining for gunsmithing, what epoxy can I use to fix my bow) may be discussed in /diy/, but discussing weapon-specific techniques/designs or the actual use of weapons is disallowed. Things such as fixed blade knives or axes are considered tools, things such as swords, guns or explosives are considered weapons.
- No drugs or drug paraphernalia (See Global Rule 1). If you want to discuss something that could involve such things (e.g., carving a tobacco pipe from wood) that's fine, but make sure it's /diy/ related and doesn't involve drugs or it will result in deletion/ban.

This is the thread to discuss everything machining related. Lets talk about speeds and feeds, your shitty home brew cnc router and the bottom of the barrel pay this industry has.

Illegal cave home

No.2224417 View ViewReplyLast 50OriginalReport
How feasible would it be to find a small cavern or cave network and live in it full time? I was thinking of dealing off the entrance with a fake wall, which will of course be one of many investments to the palace of Golem.

- cave network
- concealed door
- ventilation?
- need a place to store my motorcycle

What else do I need here? I can roll a mattress in there no problem. I just want a chill space to eat snacks if ya catch my drift.

Bladesmith general 2

No.2193543 View ViewReplyLast 50OriginalReport
Well they are finally(99%) done. My 4 piece lamb and chicken butchering set. Took me ages to finish these. They're made with cpm cruwear, which I underestimated how difficult it would be to hand sand, and the handles are stabilized amboyna burl.

Had the blades sent to a professional heat treating service, so these guys should have top tier performance.

A 1/4 cleaver in cpm cruwear is probably the best kind of overkill. Ha.

Window ventilation

No.2231093 View ViewReplyOriginalReport
Hi, moved into a new flat and had one of pic related on my window. The thing is that in the morning the street gets crowded with cars and the exhaust gas kinda get into the pic related and i can smell it from my bed. So i closed it with duct tape but now i've got huge humidity stain and mold on my wall and hardwood floor.
Is there a model that can be sealed close when i want and open when i need ? so i can ventilate during the night and close it in the morning?

How can I make money off 3 acres?

No.2211678 View ViewReplyLast 50OriginalReport
The wife and I will be moving to a 3 acre lot in about 5 years. Half an acre will be taken up by the yard/house/shop which leaves quite a bit of land to work with. What can I do with that to make some extra money?

I've considered cows, chickens, or hay. All of which don't look like they'll have much of an roi if any

>What printer should I buy? [Last updated 12-8-2020]
Under 250 USD: Creality Ender 3 (Pro), Anycubic Mega S
Under 500 USD: Qidi X-One2, Creality CR-10, Anycubic Chiron, Prusa Mini (If you want to wait months for it to show up)
Under 1000 USD: Prusa i3
Over 1000 USD: Lulzbot, Ultimaker, Markforged
SLA: Anycubic Photon, Elegoo Mars, Prusa SL1, Formlabs Form 3
Instead of buying a new printer, you could consider building your own: https://reprap.org/wiki/

>Where can I get free things to print?
https://www.thingiverse.com/
https://grabcad.com/

>What CAD software should I use?
Variants of professional programs such as Solidworks (lol paying for software), Fusion360, Inventor, Onshape, and AutoCAD may be free depending on your profession, level of piracy and definition of ''free''.
Most anons use Fusion360, but some /g/oobers prefer OpenSCAD or FreeCAD. If you want to do free-forming and modeling, Blender is alright. Also while not necessarily a design program, Meshmixer (free) can be extremely useful for tweaking models to print.
