Hey I'm looking to start learning about metallurgy but I don't know where to start.
Can anyone recommend some good books or videos for someone new to the subject?

Understand the iron-carbon equilibrium diagram thoroughly. It's a good starting place. Always start with steels. Also learn the different terms such as eutectic, peretectic, monotectic etc.
>>
>>964572
Also learn the critical temperatures of steels (if you plan to work with them). steel behaves rather weirdly at some temperatures and shoes some retarded colourations.

Checkout De re metallica
There is a copy available online at

It's an early book on metallurgy from ore to finished metal.

If I want to have something that runs off three AA batteries run off of a non-battery power source, is it as simple as hooking the ends of it to a 4.5v supply?

Hey /diy/, i want to hang 50 of my old yugioh cards from the bedroom ceiling. I haven't been around too many arts & crafts to know what would be best for this project. I was hoping you guys could help?
If possible I'd rather not put holes in the ceiling, or risk tearing the cards too much. I also have a fan in the room. Is there something i can to use to weigh them down, so they don't fly all over the place?

Good morning /diy/
Next week is my spring break and during that time I'm planning to ginally take care of my garden.
Here is a pic of my garden currently.
First - Find wood pallets. Remove the planks and stain them a dark color. I'll drill them to the bottom part of the back wall up the bottom edge of the wall planters.
Second - I'll plant the top grey part of the wall a white color so it doesn't feel so enclosing.
Third - Paint a mural with spray paint. I'm working on the design right now.
Fourth - Those bricks at the bottom are sorta lined up to the area I want to turn into a garden against the wall. I also want to make some vertical plastic bottle planters to grow veggies and such.
My only concern is whether to make a small wall using cement, etc and make the wall a place to sit; or to save myself some time and money and just make it a decorative barrier.
Currently leaning towards the latter. I'll buy some of those big concrete blocks, dig a small ditch around the perimeter and partially bury them. Paint them later too.
Fifth - Make my own brick grill on the left wall in between the tiles and the rounded part of the proposed brick planter. This is probably the hardest part and final step before I have finished my garden. I've never done any brick or cement work in my life so I have to investigate how to do it properly. This last part might be left for next month or whenever I have the cash to finish it.
Things I have to keep in mind:
I live in the tropics at a high altitude (Bogota, Colombia).
Currently going through spells of drought, the sun hits hard at high altitude. But the normal weather here is rainy and a sudden torrent isn't at all uncommon.
I also live next to a naturally protected area. A swampy lake to be specific and humidity is often high.
What do you guys think? Any suggestions?
I hope to use this thread to show my yard progression as well as noting good ideas and helpful tips.
Can't wait to start /diy/!

If you look at the OP pic you can also see a red part of the wall.
Here is a close up and the stucco or whatever was in front of the brick started chipping due to humidty.
This is the only part of the wall though that seems to be affected by humidity.
If i want to board up part of this wall I guess I have to make sure the boards are water proofed to prevent rotting.

I feel like this could be perfect for painting the back garden wall. But I don't know if it can be saved.

But without access to major machinery or excessively dangerous chemicals, would anyone have an inkling on how to "hollow out" a stump or similar piece of wood so the inside could then be burned to look like this? I was toying with the idea of those "stump out" products but am afraid that if they worked, in any fashion, the structural integrity would be far too compromised.

With out chemicals or tools, you might as well sing to a tree so the magical fairy inside will leave, and then you have a hallow tree.
But no really, your a pansy.

>But without access to major machinery
You don't need machinery to cut wood. Buy an axe and start hackin. Once you get a bunch out, hack the other side. Remove the rest with a sawzall if you have one, otherwise it will be a long process with a large knife or something. Either way it's simple, you then take it outside, carefully wet only the outside of the log with a rag until it is soaked evenly, fill it with charcoal, burn for as long as you want, then get to sanding a flat surface.

Any tips? trying to replace a plastic part that broke from the solar roof of my car.
So far, I've seen that fine sand (90%) + bentonite(8%) + water(2%) will do the trick for molding. Is this OK? Are there better alternatives?
Also, will be using wood coal for the kiln. Is propane necessary?

Too brittle.
Too much oxygen.
You would have to drink a lot of beer to get enough aluminum to cast things.

Propane isn't necessary. Built a coffee can furnace and melted some shit on my terrace cause I live in the city. Worked like a charm

This is pretty neat. This guy collects examples of DIY shit that Cubans made due to the collapsed economy. More out of the lack of industry rather than lack of personal funds.
TV antennas made from metal cafeteria style trays were commonplace during this time. Another neat example is using grapefruit rinds as a substitute for beef steak. He said they remove the acidity then fry it in garlic, onions ect. so it tastes and feels similar to meat.

for living in a van, would I be better off buying car batteries or a few back up power rechargeable batteries. Someone suggested before getting golf cart batteries as they're cheaper and would meet my reqs. I want to be able to run a big flat screen LED tv, a high performance PC, a PS4, a microwave, and a fridge at the same time but rarely.

Thats going to be a fuck huge current draw...unlikely you'll be able to keep much of it powered up for much more than 3-4 hrs...go deep cycle gel cells and hope for the best...

>big flat screen LED tv, a high performance PC, a PS4, a microwave, and a fridge at the same time but rarely.
heres what to do. Take each of these vital-for-virtual-existence necessities above, add it to the phrase "average power consumption of .." - Google it, this will give you a figure in watts. Add all these watts up, then, come back with this figure - this is how much electricity you need from your batteries. Plural.
Heres a clue, before you start tho - its too much. Even assuming you had the battery capacity to run this shitload of crap, how in fuck are you planning on charging them?
&SAGE.

You are obviously new to vandwelling.
You are going to be able to charge your phone and run a small very efficient ultrabook.
Maybe a fridge.
You would spend more on your electronics system than your van to be running that shit

if that doesn't do it, unscrew with a wrench at the base of the aluminum drill handle.

Thanks pal literally a minute after posting this I pulled the bearing back and the drill fell to the floor. I laughed at my ignorance.

Wait. How did you get it on there in the first place without knowing that? That's not the kind of fitting you can just plug in without moving the collar.

I have a new piece of tech in my home- an AT&T home cell phone. I plug in a handset and it operates as a cell. Saves me 40/month. I want to boost the reception. I assume I could replace the antenna with something bigger and it would give me more bars. It says it uses 850/1900mhz, and the cell boosters on amazon are 200 bucks. As long as I had the right attachment/connection, couldn't I use some sort of wifi modem antenna that costs 20 bucks?

Wifi antennas are 2.4/5ghz, so that would probably be worse.
You could get an antenna of the right frequency for not much more money and use that. You don't need a cellpoh e booster, you have half of one already,you just need a Bette ranetnna and google Fu
If you have two or three bars already that's fine too. Or walk around with your house looking for a better spot.
You can plug it into any pho e jack I. Your house and wire the whole house just go out to your demarc and remove your wires from the nid so your not picking up the battery or epress dial tone signal
>>
Follow the same rules as positioning a wifi router. Place it as high up as you can. Put it in an open area as far away from large metal objects as you can. Run a cable into the attic if you need to. I find it hard to believe that you'll have range issues at those low frequencies.

These things aren't rated for the attic. They oveheat in a couple weeks.

The weather is finally clearing up and the yard/garage/estate sales are starting back up again. So its the time again! Haul Thread!
You know the rules: No new stuff, no foreign stuff, don't post unless you have a picture.
The following pictures are about a months worth of stuff. A little here, a little there and then a ton of stuff yesterday (Saturday March 19th). The Craftsman carpenters box (the big one) set me back a princely sum of $10. It includes the tray and the original wooden support for the lid. I got the smaller Craftsman at the same sale for $6, also with tray. I also got the Pony pipe clamps ($4 each), Craftsman (OEM Millers Falls) eggbeater drill ($6), 50 ft.measuring tape ($3), new, unused Irwin expanding bit ($3) and new in box, still sealed Craftsman Kromedge router bits ($8) at the same sale.
At another couple sales I picked up the Stanley corner clamps (1 steel, 2 aluminum), Vice Grip clamps, and a Channellocks fencing tool, the flex chaft tool w/ Jacob's chuck and a 1/2 inch Craftsman chuck.

Next up is this beautiful Craftsman top box that the previous owner painted tomato red with a rattle can. On a related note, anyone know how to get spray paint off of decent paint without ruining the decent paint under it?
The large clamps are J.H. Williams, the smaller ones are Cincinnati Tool Co. Paid a buck each. Dremel 100 ($3), Craftsman 'Yankee' screwdriver ($4), Stanley Yankee ($2), Stanley push drill ($2), Supreme Versamatic (2 for about $5) and a Supreme Versamate ($2), mortising machine chisel ($1), Craftsman ratchet extension (forget), Stillson pipe wrench ($5), Easy Driver ($1), Omega caliper ($1) and a small new looking grinding wheel ($.75). The measuring tools in the back are both Starrett.

(didn't post this in /wsr/ as it's more of a discussion than a specific request)
Plugged in a 750GB external drive (fat32, I think it came that way) and had errors while trying to copy some files.
I was able to move 85% or so of the files off onto other drives, but there are still some corrupted files left behind.
During moving and running chkdsk /f, some of the files "disappeared". At last check, there as about 60GB or so left on the drive, but the amount actually visible in explorer was far less than that.
I haven't written anything to the drive and I don't intend to till I can get the rest of the files off. I initially tried running chkdsk, only to sit there and watch it stuck at 0%. Presently it's been running for 16hrs or so and it seems to have gotten stuck at 20%.
At least it looks like it's working and putting the damaged files into FOUND...
Any suggestions for what else to try?
Should I close chkdsk, and try running it again?
I hoped recuva would have been of some help, but it said it wasn't able to run on the drive.

chkdsk is destructive, should not be using on 15%+ corrupted drive, just going to make tings worse.
As long as drive still recongised (appears in exploerer, etc), file recovery program (Easus Recovery myself) would be a better idea. Yoos chkdsk /f only for odd minor file errors, and preferably not even then.
Weigh up how much you really need the files as well, 60GB of mostly corrupted data probably gonna stay mostly corrupted, no matter which drive you transfer it to - if films or some BS you can reload, forget em.
>>
>>964668
well, considering there were only a handful of damaged files on the other parts of the drive, I don't think all of the ~60GB left would be corrupted as well....I did managed to get a few files that were in the same folder(s) before the rest disappeared
but I'll look into it, thanks

Never write to a dodgy disk.
Buy a new disk, image the old disk from it, make a copy of the image, and work on that copy.
If you shag up the copy, you can just copy it again. If you shagged up the image, you'd have to read it from the dodgy drive, and it might not put up with that kind of treatment.
If you work directly on the drive and you shag it up, then it's game over. Assuming it even possible to write to the drive reliably, which it may well not be.
So trying to wire my rc toys slide switch to a newer one that fits a mount on it. Problem is, it's a 3 stage switch 6 pin, so it has 3 selection settings as apposed to the old on/off selection setting 6 pin to the left you see here. I got 3 main cables, the negatives, the control board positive and the battery positive on the far right. Since I'm trying to rewire it onto the 3 selector, how would I go about doing so so that it's still an on/off switch. I'm still a novice at requiring as I blew up a battery in my face yesterday. Got a multi meter for that now.

resolder wires so behavior of new switch is the same as old switch
