>more modern drill bits have carbide tips

"Modern" twist drills are all high speed steel, or they are solid carbide. And complete solid carbide twist drills are specialized tools.
The only "carbide tip" drill bits out there are fucking hammer drill masonry bits.

Your opinion is shit because its based in ignorance.
>Furthermore, more modern drill bits have carbide tips

what kind of moron are you
>he doesn't use sharpened tungsten carbide drill bits to drill hardened steel.
How the fuck would you know if this is a good investment Of OP’s time?

Self loathing people will impart their own feelings on to someone else. Mayby cleaning up these stools are not worthy of your. Maybe you’re just jealous that op found these items and is taking the time to restore them.

Either way a physiologist can help you with your self loathing behavior
No I dont
Too expensive and too brittle when HSS-Co bits arent that much more money than standard HSS and will eat through hardened steel all day long.

I finally bought into the solar meme and installed an outlet. Here's my supplies, it's a pretty basic setup but now I can run most of my tools for free, recharge cordless drill batteries, my phone, etc. I can also run the fridge for about half a day in the event of a power out. What are you using around your place that's solar?

or for people who don't want to spend lots of cash on gas they have to travel over 50 miles to get, plus oil/filters and other things. Solar works if you get your appliances to run natively off your voltages, with batteries and high capacity capacitors to act as the main storage. Wind and other alternatives(non-blades/low wind setups only) with a optional power draw for high output beyond normal usage options setup.

Propane, while VERY EFFECTIVE FOR HEATING/BURNING, not so effective when needing to be repeatedly refilled/recharged.

Land and property are needed for these systems to be efficient.

The mafia is also involved in cheese production. Does that mean cheese is no good?


You cant drive on top of a coal plant either does that mean coal power is no good?

>A higher cost. Not lower

They buy from me at 4c, the absolute lowest price they paid over the last month was $38. So Ignoring all transmission annd conversion costs I was being subsidised for 30min in the past month. But tell me more about my energy market.

But that is just the dollars. If you were being fair and included the cost of environmental damage then we have been subsidising fossil fuels for ever.

Yep there was more investment in renewables than coal in the one year your report looks at. That says nothing about the trillions that have been invested in coal.

>I said solar production is far worse than burning coal for power.
>I gave u proof.
No you posted an article from a magazine that talks about silicon manufacturing. It made zero mention of coal.

No one is saying solar pv is perfect but it is without a doubt cleaner than coal. Before you post a heap more tangentially related articles why not read them, think about what they say, then try to make an actual argument with the information they present.


Can someone please explain me how he's making a coil winding machine from a 3D printer?

Is it just an attachment to the 3D printer (what part of it?) with a wire feed tube and a metal roller? How would the design of this look?

Also, how is he using the 3D printer exactly? He's not actually printing the wire it looks like. I am very unfamiliar how 3D printers work, so if anyone can explain that would be very helpful.

Also, he said he's documenting his work on his website page here, but I don't see it. Can any anons point out where it is?

Oil Furnace help

Ran out of oil last winter & system shut down as it should. I've done the maintenance for yrs & knew what to do.
I hand pumped the line free & clear, changed the oil filter & fuel nozzle. This time no combustion. Checked inside hot box & didn't see any mist (atomized oil). Everything else was checked also; transformer,cad cell,burner fan wheel & primary control.
Opened fuel line from pump to electrodes & no fuel. I replaced & primed the fuel pump but still doesn't pump fuel into the the ignition assembly.

Any suggestions ?

Ps the stack switch/primary ignition relay in pic has been replaced

upgrade to natural gas
I wasn't just "swapping parts" . An updated Prime Control & cad cell rely to replace an outdated Stack Switch is real work. Removing & cleaning the motor housing, coupling & burner wheel, the electrodes & replacing the fuel nozzle wasn't "swapping parts". Flushing out the fuel lines, changing the filter...all this is real work. Go back to your moms basement.

This may be stupid but does your pump have voltage? Is it energizing?
Is there a valve closed or some sort of blockage in the fuel line?
Quite often, this stuff ends up being the most simplest solution.
Check and make sure that your oil line saftey valve is still open.
Are your master switches closed? You should have two of these btw.
Also it could be your stack control, there is usually a rest button, or you'll have to manually reset it by taking it out of the housing... Hell it could just be covered in soot and preventing ignition.

Switch to natural gas OP. Don't kill yourself.
Replace your current furnace and fuel system with natural gas or propane, or are you unable to afford that?
"Replacing the system" isn't the same as repairing the problem. LP & Natural gas are only an option if there are already gas lines ran to your resident. Oil furnaces are common in country or out the way settings where generally, electricity & plumbing are the basics.

Machining thread.
CNC, manual machining, whatever.

Fusion360, because the parametric modeling and timeline make everything very scalable and easy to modify for prototype--> production transition. Also does FEA and other analyses/simulations, and CAM all in one package.
I use sketchup Make 2017, because 2018 is shit and I don't have the hang of Fusion 360 yet. It's like the Python of 3D CAD software.

Take critical dimensions into consideration, and break it down into function. One can measure surprisingly well when going over everything and eliminating conflicting dimensions (compromise with the least important ones).

Bolt clearance holes -> not a big deal if you measure a bit off and add some clearance.
O-ring grooves-> measure a couple of times and compare to standards.

Everything I've read from even Tormach fans says go straight to the 770 or 1100 because the 440 isn't worth it.

It's useful if you know some basics of manual machining. Especially if you know tricks like the best machinists' uses for sine bars, parallels, multimeters, and surface plates.

So I'm currently renovating my basement and I've come across this crack that starts at the window and goes down to the floor. Am I supposed to be worried about this, and what can I do about it except call a contractor?

Just bought a house, noticed a few doors don't want to open/close all the way.

Is this a super common thing to happen to houses or a sign of some foundational issues?
From what I understand it's all about changes. If you had a door that was perfectly fine for a couple years, then all the sudden won't shut, that means you have active shifting (which is differential or else it wouldn't be noticeable) which is bad and needs to be addressed. Having no history you can't really tell if it's this or the person who hung the door just didn't do it correctly.

If you're really worried you can hire a structural engineer for a few hundred bucks to do a full workup and tell you what's up.
I have a 19th centruy house with cracks way bigger than that, and its still holding strong. If it was going to collapse, the banks appraiser wouldnt have let me buy it.
Are you that guy who said he was a really good math teacher, and when I asked for pointers on how to improve my math skills, you said if I don't understand math, you can't explain it to me? Because you sound an awful lot like that guy.
Super common. It's summer and all the wood in your house is at peak moisture. Check the screws in the hinges, make sure they're tight and the jamb isn't cracked. Wait until winter and see if you still have a problem trim the doors.

>>>/g/ might be a better place to ask
If you want to do it yourself then you have your answer.

I'm a linux admin, programmer, droid app developer with lots of dba, javascript, perl, and html experience. ie, a person that could make the thing you want. If you have specific questions ask away.

Basic advice I'd offer; KISS. Go buy a VPS for $15/yr, start with a basic LAMP stack, HTML front end to mysql/postgresql db, tailor a mobile version of the site for phones. Forget a native app, you don't need it.

Once you get it up and running and decide to keep it (after deciding usability) Buy a second VPS at another provider in another town and setup a redundant server the syncs with the main one. Also you should do daily backups to a computer you own on media you physically control. NEVER TRUST YOUR DATA TO A SINGLE PROVIDER. They will lose it and give zero fucks.
You could call microsoft or google office sales. You can probably do it with one of their off the shelf apps, because literally everyone does this. Like microsoft invoicing or planner, or sharepoint could all do this.
Why lamp? Lemp. Node.js. Even just plain node most of that shit works out of the box. Keep the Lemp for phpmyadmin.
Because Apache is more established, documented and simple. If he was building something that would need to scale into the millions of views per day sure, go Nginx but for this little project, KISS.

Also, fuick node.js.

I don't get this spoke arrangement. What is the reasoning behind it?

I'm trying to model this thing then print it in resin.
6 replies and 2 images omitted. Click here to view.
I found what this is:

"Lunokhod wheels are a 4 flanged 3 rimed design with zerodish. The outer flanges connect to the outer rims with 8 spokes 1 cross. The inner flanges connect to the inner rim and the outer rims with 16 spokes 2 cross on each flange so that each rim has 16 spokes. The inner flanges provide the lateral strength of the wheels. Unlike all bicycle wheels these were designed by a scientist. It was not known what the terrain would be but it was expected to be 6 foot deep dust. The wheels performed flawlessly over their design life covering up to 37 km at speeds up to .1 kph. Each wheel supported 40 pounds but were tested at six times this weight. "

>print it in resin
steel tensile strength is many times stronger than resin, maybe even 30x. I doubt 3d printing the spokes would even hold the model up under its own weight with those proportions. You going to make the spokes out of a different material?

This is what I have now. I think I will leave it at this.

I will see what works, they say these resin things are very accurate. I just bought one off Amazon, didn't try it yet.

This is going to be a hollow a scale model of the rover, I'm not planning to ride it or something.
probably like when you mount a table top or something via crooked legs that twist it to hold it more solidly than just sitting on a couple legs.
the important thing to remember about the spokes is likely that they are solidly mounted at both ends, so they can apply uneven pressure to hold the wheel better.

You could probably scrap the CRTs, replace them with cheap Chinese LCDs and save lots of money in the long run in energy cost (+AC to counteract heat load).

What in the world would you need 15 diy oscilloscopes running at the same time for?
a secret. it's really important though
Well in any case, you should take out a watt meter and test them individually to see what kind of amperage you'll need. Check your breaker box and see if you can fit the required number of new breakers in the panel. You can always replace the panel with a larger one to fit more breakers, but be careful not to overload your service line (200a 220v is common in us for new construction). Wiring new circuits is fairly simple, but if you don't fully understand, you should hire a sparky so you don't burn down your house.

I want to make my own desk. I think I'll go for a cheap particle board or MDF. Is there something I can fuck up in particular? Edge banding seems to be the most difficult in the process. I'm going to cut the board with a jigsaw which I don't even have yet. Will I need a guide for cutting a straight line? I've seen some people making jigs for that. For assembling everything together I think I'll use just screws and pins, cam connectors seem a bit more troublesome.

I could skip cutting and edge-banding altogether by paying about $60 but I would prefer to do it myself unless it's actually pretty difficult.

I once made a desk out of fast food lobby table tops when a local mcd was remodeling.. they were like 1 inch thick and had a thick wood like laminate on them.. they were durable as shit... took some small ones and built a tower then atatched the 2x4 one to it and a commercial table leg from one oft he tables on one side... total cost $0 dollars. was fun to build it, didnt have to cut or sand or anything... just attach them together with screws and threaded rods. eventually that desk didnt fit my needs and was decomissioned to my shed where I used the large table top a a workbench.. pic related. dont mint the chair I had to block out somethign that was sitting in it. pic is very old so I know its shitty quality.. didnt have good digital cameras back then. but you can make out the table tops and the tower made with the small ones. i wish had taken a pic of the desk after I built it without all the shit on it. it was a good desk sturdy as fuck. the bottom shelf on the tower had wheels and on the right was the stationary leg. so it was semi mobile i could move it but it wouldnt move as I sat and used it like the damn desk I have now that has 4 wheels as legs. I swear if I get the opportunity to come across any tops like ths again I will rebuild that desk the same way cause now with smaller hardware and needing less space that desk would be perfect

This is a great point and is why I don't sign up for store credit cards. A little saavy shopping as outlined above can save a lot of money without having to risk my social security number.
The hard pull on your credit isn't worth it
Usually with a stupidly high interest rate. Avoid store cards and store branded cards whenever possible.

What are some romantic ways to improve my plumbing? I've already sealed my leaks with dripped wax and increased the girth of pipes coming from my toilet
16 replies and 1 image omitted. Click here to view.
Licensed plumber here, remove the restrictor in the shower head and vacuum breaker in the kitchen faucet if it has a pull out spray head. Much more gpm.
Tear everything out.
Dig a moat around your house.
Build an overhang, out your largest window and extending over the moat, with a bench seat that has three holes for toilet seats.
A blowout type toilet.

As oppose to a siphon jet.

Typically wall hung, so You would need to rip the wall out and install a carrier.

Used for commercial/public applications.

The split toilet seat is for sanitary reasons. basically if you have a cheesy sausage, it's not going to touch the seat, and potentially cheese up someone else's.
anon...leave that plumbing alone..it did nothing to warrant your wrath, go outside and play...
