tl;dr: post shit about how to machine or manufacture shit here. Being able to make shit makes you more of a man with bigger balls.

Lets start on the political side of manufacturing with a USA centric theme.
Once upon a time, USA was the best. It was the best because it allowed anyone to build anything they wanted and purchase anything they wanted. After all, things you own are tools, and tools are needed to survive. Why should the government put any kind of restrictions on tools needed to survive?
Well, over the years, that is exactly what they did, because the more difficult it is for you to survive with less (or incorrect) tools. The more difficult of a time you have surviving, and the less you can do something about the government.

The greatest of all these is the ability to make more tools or better tools. In the modern vernacular, this is called machining, manufacturing, fabricating, and a lot of others that are more industry specific. I suppose the second greatest ability is to be able to protect such things, but that is outside the scope of this shitpost.

Why is the ability to build [tools] important? Because it lets you, the invisible hand, be able to swiftly deal with governments (problems) how you see fit in ways that nobody can anticipate. Why do you think policies being pushed through has been moving businesses over seas? The government does not want you to know how to make shit. Workers unions have not been nice either, but as near as I can tell that is the result of a different symptom (greed). In either case, bureaucracy is a hindrance to market (you: the invisible hand’s) agility.

I could rant about all the stupid shit in various markets that result in what I already said, but instead I’d rather focus on shit that will make a better life for you. In general, focusing on the use of lathe and mill work. Lets start with the stupid basics.

Example of CNC lathe in use: https://www.youtube.com/watch?v=lcGHtI9Lql4
Example of CNC mill in use: https://www.youtube.com/watch?v=wHstzxuryMk
Admittedly both examples are with machines that are a bit fancier than what might be typically found, but that does not change anything other than how many times a part is handled before it is finished.

Using a lathe is called turning a part. Using a mill is called milling a part. Turning and milling parts, along with some of the more exotic methods of cutting material (such as waterjet or EDM or centerless grinding machines), is called machining.

While I don’t follow the religion of safety (the reason why ppl are so worried about C-19 to begin with), there are certain things shat should be done or not done to keep all your limbs attached to your body. Things like leaving the chuck key in and walking away. Or wearing a long sleeve shirt and reaching around the quill of the mill while its on. Don’t be a dumbass and instead use that head attached to that white neck of yours.

What I’d like to do from time to time is post in here about various machining and manufacturing practices, tips, tricks, and methodology at large.
Remember though, its not about me, its about giving you the knowledge and tools to become richer yourself. If you have a question or something related, go ahead and post it.

One of the things I've always wondered is where you can find the most local wood mill.
I have known several people with their own, but I can't imagine trying to find one after moving to a new place.

Band-saw mills (portable or fixed) are much more common these days, and alot of millers/sawyers have listings on faceberg. Also, check with any local tree services, I guarantee they know someone.

Whether milling or contracting (fully 60% of my income is from private subcontracting) the most valuable thing you can have is a reputation for being a solid, hard worker
Especially as things get more hairy with vaccines and mandates and shit, if you're out in the country you're within a 10 mile radius of prolly 5 ranches that need hard workers. And, when you do good work, they'll tell their friends.
Dont wanna do subcontracting? Neither do I, but you better if you wanna have the social connections you're gonna need to survive when supply chains shut down, and infrastructure begins to collapse.
Just finished a 3-day job where my cut was 1.5k for 1400' of 4-strand barb wire. Dont worry, Ill get back to playing with wood, this iz just some theory/philosophy and a bit of strategy.
Cuz rn, especially with everyone scared of covid, its near impossible to make a living with a private mill. But, if you can establish yourself as a hard worker and contractor - ideally with periodic fine wood products for sale - who also happens to have a mill, your reputation will precede you. Especially if you're the guy who's missing a finger tip. Literally, they call me pointless.

Heres a pic of a recently cut post-oak stump. You can see the initial cut on the right, with the drop-cut on the left (drop-cut being the cut that causes the tree to fall). The thin spiky section is what holds the log until it hits the ground and separates from the stump. You want this, as it helps to guide the log during the fall. NEVER CUT TREES DOWN IN HIGH WIND. Ask OSHA how many fatalities they have from people thinking that a breeze wont affect the dropping of trees.
Also, nrver drop trees without a spotter. By that I mean, never drop trees without someone watching everything going on, ready and waiting to grab ur ass bybthe collar and drag you away from getting killed.
This is NOT hyperbole. It is astonishingly easy to get yourself killed while felling logs. When felling trees, if the log grts hung up and wont fall cuz of another tree, they call those 'widow-makers'. That too isnt hyperbole. Please be safe.

The pad is 12'x18', ~5.5-6" thich, with 5" deep footings along the perimeter. The metal structure is Cattle fencing (cuz rebar is prohibitively expensive rn, as well as more rust-susceptible) running across the bottom, with scrap pieces running vertical along the footings.
This is to accommodate my mill, which is ~5'x16', leaving an area to remove, trim and paint the board-ends before running them into the kiln. The problem with portable mills is levelling (and relevelling) the bastards on soft ground, especially after heavy rainfall. NOW I can set it and forget it, and more than double our production, without cutting into contract work.
One thing I DIDNT appreciate when starting out is just how much organization, planning, configuring, reconfiguring, and development has gone into an already established company. But thats ok, by the time the weather starts to warm back up (its Texas, so early Feb) we will be running solid, with opportunities to further develop the business property in between jobs and such.

It fluctuates. This time of year, maybe 2x a month; spring thru fall, anywhere from 6-12+ times a month, depending on clientele. It usually takes about 1/2 hour on soft, uneven, or off-level ground. The pad wont help for that, but it will allow us to get the mill set back up at our place in about 10 minutes with no need to check the level after rainfall. Plus, we can extend our hours of operation because the work area will be stable, safe, and clear of hazards and obstructions cutting a finger off amps one's safety-consciousness. Moreover, once we get a tin roof over it and a few light ballasts, we can run after dark, allowing us to concentrate as many operations in a day as possible, maximizing production and allowing us to get more ambitious with the number/intemsity of the jobs we seek and take on.
Its all super meta and boring details, but Im excited AF with the possibilities.

A few things about milling.

In order to maximize the usable wood from a log, you'll want to start with 4 full-length cuts as pictured (the flat parts). This will partially cant the log, making it more manageable for later setup. This method takes longer than just slabbing it out (routine horizontal cuts), but the result is a better product.
After flattening all sides a bit, you'll want to cut as thick of a chunk off the top and bottom, and set them aside. For me, thats about 6.5-7" (without scraping) thick, which later will be put back on and cut into quarter-sawn boards. Ill go into detail about quarter-sawing later, just know 'its better'. The vertical oriented boards in pic 1 are quarter-sawn (except thr corners,
Once you have the rounded chunks off, its just a matter of slabbing up the middle, determined by the purpose.
In pic 2, we are cutting to make an epoxy counter-top with a matching island.
Note: we NEED 3 pieces, but we cut 5.
Always cut more than you need. The most retarded-ass circumstances can foul an entire board, and theres no sense cutting into another log for one board of you can help it, especially given the amount of drying time that is necessary
In short, its always better to have more wood than you need, rather than less.

When milling, you'll want one of those painter blades that look like a giant spatula, for cleaning the sawdust off. Pretty much all portable bandsaw mills use water to cool and lubricate the blade (a dab of soap helps too), so the cut face will always be wet and caked with sawdust. Scrape that shit off, all of it, cuz that dust will mold and stain the surface of the wood. Its not the end of the world of it does, but to restore the surface you'll need to sand more surface than you may want to. The boards in #2 are cut to 1.75", to have a finished thickness of - quoting - 'anywhere between 1 and 1.5". We should only have to take a 1/4" off to finish it but I can always make the board thinner later, and unless no one likes you, there is no such thing as a board stretcher. So, erring on the side of caution is generally advisable, until you're at a point that calls for precise/finish cuts.
Quarter-sawn, rift-sawn, and straight-sawn wood

The type of sawing/board refers to the grain pattern of the board. If the board has vertical grain through its thickness, its quarter-sawn. If the grain is diagonal, its called rift or half sawn, and if the grain is horizontal through the thickness, its straight sawn.
Quarter-sawn is the strongest, most durable, and least susceptible to warping, flexing, expanding, etc. when wet. Quarter-sawn is the exclusive choice for doors, frames, flooring, etc for these and other reasons.
Half sawn wood is stronger than straight, but is.more susceptible to warping as it dries and is usually reserved for posts, furniture legs (especially when turning them on a lathe) and other pieces that are likely load-bearing in some capacity.
Lastly, there's straight cut. Basically, every construction grade board you will find at a lumber store (unless specially order) will be straight sawn.
Straight sawn boards are strongest along the length of the board, which is why theyre reserved almost exclusively for construction.

The bottom board from the cant will always be irregular. This is because as thickness is removed, the board expresses its elasticity more, and unless the mill has a completely flat deck (Ive never seen one), the ends will hang off the risers. The board pictured on the mill is 1.75" in the middle, but 2"+ on the sides. This can be brought to uniformity but it can be tricky, so until the job is done, consider that an 'emergency use' board, and plan so you dont have to use it.
Also, I do NOT recommend hydraulic/automatic mills. While they have dofferent settings for different wood types, and they unquestionably go faster than hand/crank-powered mills, there is ALOT of variance that can go into one tree vs. another.
Texas pine is ALOT denser than Pacific Nw pine, because of the increased sun and high levels of moisture. They take longer to dry, and theyre alot heavier and stronger than PacNw. Theyre also harder to cut through. Leaving the machine drive to a hydraulic.motor and a computer MIGHT get more cuts done in a shorter amount of time BUT it wears out the blades MUCH faster, causing curve in the cuts (very very bad) or outright failure of the blade. The machine cant compensate for knots either, whereas you can see and FEEL the density of the wood when its hand-driven.
Me? Id rather take 30 seconds/cut and get a superior product than 15/cut and have to reject boards because they have inconsistent thickness cuz I was in too much of a hurry. Take your time and go slow.

Well shit, wasnt expecting rain today. Oh well.
Look at that woodgrain! Isnt it gorgeous?
The darker parts are called spalting. Literally, it is the onset of decay in the wood. Its tricky to catch the wood before its really started to decay, but while spalting will downgrade (decrease commercial value) production lumber, its desirable (ideal, even) to woodworkers and crafters.

I'm afraid you guys will have the Russians airstrike my position. I've seen what weaponized autism can do. There's no way to post my metal work without doxxing myself and posting my wood wouldn't do much unless you really like gazing at other men's wood.
Maybe I'll have something to contribute if I can get a milling machine or new welder, but there's nothing I could teach you that an old pro couldn't do better.

Thank you, I appreciate the qualification. It will come as no surprise that exhaustion, frustration, and working with an unusually small piece that contributed to the removal, but the main issue was that I wanted to be DONE for the day, and I let my safety practices lapse for a moment.
While Im clarifying, I should point out that a jointer doesnt cut digits off, it shaves them away away, layer by layer. And yet, even though the finger only made 'contact' for about .1 seconds, that was enough for about 30 rotations. It was gone before I even registered the occurrence. A mere fraction of a second, and Ill never be able to game the same again (my left-trigger/right-strafe finger is too short nao ~_~)
Fun fact, the experience felt like a mix of smacking the finger REALLY hard (but just impact, no pain) and then losing all circulation. Ngl, it was way milder than I had anticipated.
But to you and yours
>I've always put safety above all else

That's why I don't post stuff that I've made over the years. Most of the stuff I make is pretty specialized and can likely be traced to two or three sources (including me) just based on the part and what it's used for.

Just mix eggs into it. Or if you want to be /vx/, blood. Either rot quickly and release gas, foaming it up.
Doesn't do well for mortar, though, because it ruins repairability - mortar should always be weaker than the bricks it's binding so in a pinch you can remove and replace it, and the super-strong cement mortars you can get with eggs and pozzolana won't be removable.

That's pretty accurate. There always comes the time when you think you're knowledgeable and experienced, get careless, don't follow the safety procedures, and boom! At least it's an opportunity to literally write the rules in blood.

Ah, we differ in that regard, Im quite looking forward to someone trying. To qualify that, I have enough business that I can be choosy about who I do work for, and all of my current business contracts have already listened to more than one rant about the jews.

Hey /ub/ ever had to clear a large plot of land in a short time? Dont have a brush hog?

Put a metal-cutting cirxular sawblade and put it on a weed eater. This thing is beefy enough to cut through up to 4" stumps in seconds. Quit trying the weed eater, you'll just break your line on sticks and shit.
When you do, it is advised that you hold the foregrip as normal, but with your operating hand, pull the weed eater so that it is in constant contact with the full length of your right arm. Then, lock the device against your hip.
This will give you an incredible amount of control, enough to compensate for any time the device kicks out so u dont cut ur toes off. heaven knows Ive already cut enough off already.
In this configuration, one can cut down rough, uneven, stick ridden, unkempt mess at just below the speed of standard weed eating.

looks like the oil drain plug on a car engine... and either over tight, or somebody hit a rock or something, cracked the oil pan, and it finally broke with the next oil change. the oil drain plug is the lowest part, so plausible enough that it wasn't just over-tightened

Sorry guys I haven't been posting nearly as much as I'd like to. There are tons of machining things I'd like to cover, such as the different kinds of taps there are (plug, spiral point, hand, spiral flute, forming...), typical CNC lathe and mill commands, uncommon CNC machine programming practices, some pictures of some trashed tools from big mistakes that other people made that I collected and how to avoid doing such things yourself, and probably a lot more.
There just isn't enough time in the day

No way. That's the aftermath of a catastrophic engine failure and someone must've thought it would be funny to take a picture with the wrench on the drain plug. A grade 4.8 bolt would've broken off well before the oil pan.

If you're too busy to post, you're doing it right. Mlpol could have been alot of things, but it will never realize them because of the incompetence and duplicity of staff.
Wanna never amount to anything in life? Mlpol is a good place to make that happen. Nothing against ponies, but this place has been trash for a very long time, and I hope (you) specifically grow out of it. Peace.
