Ok first... i wasnt really sure where to post this but Science topic seemed the closes so i need to know whats the strongest metal(s) but still can be bent.. shaped, and cut, im trying to make 4 blades equal in length and height maybe 1foot tall each but could also be made to have room towards the middle to add some kind of gears or something to make it 'bend' back and forth (i'll attach a picture to give an idea what i mean) also, how much would it cost?

Hello Everyone, I want to screw two parts of aluminium 2014 together ..... one is a hollow cube with at-least 5 mm shell width without the top face and one is it's cap/metal sheet with 3 mm height with holes for two m12 to 8mm pneumatic fittings through which pipes will be connected... it is actually a water block ,cooling a part of my next project.. so i want to ask which kind of adhesive or gasket should i use in between them while screwing those two pieces together so that water or any other coolant doesn't leaks from the block and damages the electronic components. A non-native English speaker here, please ignore grammatical mistakes. :)

Is there such a thing? What's it called?

So, i happen to listen to alot of metal and death metal. Anyone here appreciate the genre?

Will there be another metal  challenge?

I saw this video, http://www.youtube.com/watch?v=3aVxB9oXcEc, And I am wondering what type of metal he shows you.  THANKS!!

​i want to make a metal detector using tda0161, when the detector detects the metal from a specific distance the buzzer sounds but as the metal comes near and near the buzzer sound increases!! so anyone guide me for this i want to use this with arduino and to interface it with matlab and want its code too!!

Ok so I want to get a metal detector. But i don't want to spend a fortune but don't want to spend $10 for a stinky one. I'm looking for one for around $50. I just want to look around my yard,and see if theres anything interesting (once i found a little diamond or some kind of rock).

Just finished "Idoru" by william gibson.The main character has a laptop with a cast aluminium case made from reclaimed soda canswirh semi precious stones as switches and buttons and reclaimed ivory keys. I suppuse its possible to do, but difficult... but wouldnt it be deadly? Anyone ever tried that?

I have recently completed two metal projects and didnot document them. Are they eligible for the the contest?

I was looking around the other night for information on how to separate metals through smelting, electrolysis, etc. I wasn't able to find much. I'm guessing this is still somewhat out of the range for the DIYer? My neighborhood typically has a rediculous amount of scrap metal on the curb, but the scrap yards around here only offer a slight profit on pure metal. Besides selling the metal at a scrap yard, how hard would it be to seperate the metal yourself, and just use it for your own purposes. I'm going to be investing in a metal-working lathe in the near future, and I'd rather reuse metal I've got lying around than buying it brand new at a premium. What do you guys think, is this doable?

Dose any body know how to make little pixel pokemon figures?

HOW CAN I MAKE A SIMPLE METAL LATHE TO DO HOBBY WORK IN MY SHOP PS. I DONT OWN A BANK AND CAN PRETTY MUCH DO ANYTHING WITH TOOLS ANY HELP WOULD BE APPRECIATED CHEERS!

Hey I wanna get into metal detecting, just for fun. I have about a 200-250 budget. I was looking at the Garret 250, but I really don't know what to get. Does anyone here have a recommendation, or something? ,Dano

I am trying to get an answer, i hope someone can help. i have a 12x60 trailor i use for hunting and fishing, in upstate ny. i want to put a metal roof on. the original roof is sort of a rounded dome. the rafters are 2x6, i was thinking about building it up with 2x4's to get a bigger pitch. is it worth it? also if i use 2x4's do i need to put plywood on top first or can i attach the metal roof right to the 2x4's. thanks rich russo

Does anyone out there have any knowledge on Cadam programming? I have a mini lathe and milling head and thinking about putting a Cad system on them. Would it be cheaper to just buy one already set up? Also looking for model plans to build and construct.

So I really like this clock.  I think I'll buy it soon. But as a beginner's art project, I'm trying to replicate some of the metal effects here.  I'm curious for techniques on how to accomplish some things, like: The back plate is copper, which the artist says is "oxidized".  I expect oxidation to turn copper green, blue, or black, not this silver/grey color.  Any ideas how this was done?  Is it just that it's a light oxidation? I really like the metal texturing here.  I've been able to replicate something similar on copper plate by hand-sanding in one direction with a fine-grained sandpaper.  But notice the vertical texturing on the backplate - how would that have been done?? I like the polished metal look of the minute hand contrasting with the reflective look of the hour hand.  How would you do that - similar way as the backplate?  Same with the gear? I've actually made what I think are much prettier nails by taking old (originally quite rusted) square iron nails, removing the rust and grinding the crap out of them with a bench grinder until I get a cool reflective finish.  Doing the grinding in patches gives it almost a hammered metal look while keeping the reflectiveness.  I think the effect is cool and really works with the "old-but-new" look of the square nails.  I'll post before+after pictures if anyone's interested.

Hello, I'm looking for a detailed schematic ( or two ) on a metal detector capable of locating non-ferrous materials to an extent. ( titanium in specific )  I recall finding a fair bit of documentation on such a thing a few months back, but I can no longer recall the exact method that they used. If anybody knows where I can find some detailed information and/or schematics I would very much appreciate it.  I have a reasonable amount of experience in building somewhat complex circuits, and can learn what ever I do not yet understand, hopefully. ;) I have a very good object to test such a device on, should I manage to build one. It's something I keep close to me at all times, and goes wherever I go.   ( that sounds kind of like a riddle ) On a side note; anybody had Deja Vu over four times in an hour? I think my mind is running in loops. Any help or insight would be very much appreciated.  -Jake

I saw this on youtube: http://www.youtube.com/watch?v=gNND2pxvxgU He has like 16 wires in this setup, and it generates enough power to light an LED... how much power could you get with some more wires? Say 1600? Does the thickness of the wire matter? Sorry to make you watch the youtube video, if you don't want to, here's what's going on. This guy, Nyle, uses copper wire lengths which he has heated at one end and cooled to coat each end of each length with copper oxide. He then bends the wire so that two ends of copper oxide-coated wire are touching and another end is about 3 inches from the junction. By heating the loose end, and touching one wire to another, he's able to generate enough current to light an LED... pretty neat!

Hi ! Into a terrain near a very old volcano and a river, my brother found fragments of obsidian of various sizes and colors. Some of them are "glued" to metallic stones, and some others contain marbles of metals ... He also found a heavy metallic rocks (encrusted with obsidian) who reacts with magnet, and an other light one (without obsidian) who does not react with magnet. Do you know a mean to identify those metals ? (I Googled but found nothing very useful so far) Or do you have a clue of what it could be ? #1 is a metallic rock encrusted with obsidian. It must be iron because it's heavy, the rust is red, and it reacts to magnet. #2 and #3 is obsidian with marble of metal who reacts to magnet. #4 is an unknown (metallic ?) rock. It is light (150 grams for 200 cm3 - 0.33 pounds for 12 cubic inches), of the color of silicon (or the graphite of paper pen !), does not react to magnet but is (electric) conductor with resistance near 0 ohm.

I am attempting to put a metal top on part of a wood work bench to make it more resilient.  I am planning on getting into electronics and want to make it less likely to burn . \ Any ideas on what I should use? at the moment I am thinking sheet metal, but I am worrying about toxicity ect. Maybe that is OCD but hell I am so haha. 

I'm looking for small metal gears for a project of mine, I don't have the money to pay them to ship to me but perhaps we can make some sort of deal or trade?

Is it true that there are 3d printers that print in metal? If so what kind of 3D Printer is this and about how much do they cost? Oh also how exactly does that work when 3D Printing is supposed to be additive manufacturing and metal isnt a liquid or even flexible at solid states?

Hi,I'm looking for flexible metal cable similar to that used in this product:http://www.mightybright.com/Book_Lights/79/ProductDetail.htmlThe cable has a flexible metal sleeve which can be manipulated into whatever shape you want and holds its shape.Can anyone tell me what this cable is called? I've been searching online for days and I haven't found anything similar SadAny help would be appreciated!Thanks

It's getting warmer where I live (that's global warming for ya) and I wanted to start testing my free energy instructable again. Does anybody know or have any good ideas for a non grounded big metal object or way to make one?

When I fill metal hydride in tank or cylinder to storage Hydrogen gas Do I must refilling agin metal hydride to the tank or cylinder to storage Hydrogen?

Can any one tell me which hollow meal rods are easiest to work with? I am thinking about building a hammock frame that will support at least 170-200 lbs. ( i weigh 160 but it never hurts to hold more). I wouldn't necessarily need to bend the metal rods but they should be relatively easy to cut. I want to stay away from hard wood and copper if possible. At first i was thinking about using pvc but i don't know how much it can hold. I only have hand tools and a power drill. Please feel free to post any suggestions. If you have a better way to build a hammock frame please post it here. If i figure it out ill post an instructable. I uploaded the top view and side view of my design. it was drawn in paint for brain storm so its not very detailed

Last weekend my friend Don and I went to ALCO Iron and Metal in San Leandro, CA. Don needed some sheet metal and I will need some metal soon enough and I'd never been to any such place, so I went along to take a look. It was super cool, they had all kinds of metals in all kinds of forms - sheets, rods, tubes, blocks, foil, flats, angle lengths, meshes. They also did a lot of metal recycling and had tons (literally, I'm sure) of metal scrap of various sorts lying around in heaps, and baled up by type. I started out taking photos for reference, but ended up just taking pix of anything that looked interesting or would make a good photo. The recycled metal bales were especially lovely.Here's a few pix to whet your interest, and the full set is on Flickr here: http://flickr.com/photos/mnrsiat/sets/72157605422168005/

I forget whether I'll actually get this to post, but here goes: Takes a while to load but is worth it. http://mapofmetal.com/#/home

You know those thin metal rulers with the cork backing? Any ideas where I could get that exact kind and thickness of metal? Hopefully a good bit longer.

 I'm looking for an amazingly simple metal detector schematic, anyone?

Fixin’ to make to magnetic board and need some input on what to purchase. I’m seeing several types of sheet metal. There’s plain sheet metal, zinc plated, cold rolled, weldable, galvanized, etc. Is there a particular type I should purchase? Hoping to avoid anything that will tarnish or leave marks on any paper out on the board. Thank you for your input!

I 'd like to finde an issue that was publised about making a metal stamp with a 3D printer which getw hot with a lighter. Isaw it some days ago but i can't find it. Thanks for your attension

I want to make a aluminium pedal board. Will I have issues with ground, signal etc.?

I think I may be looking to spend a few month making a suit of armor by hand.  This site had ibles for just about every peice except a helm.  Anyone know of a relatively easy way to make one out of metal without the need for a bunch of heavy machinery?

We met all sorts of interesting people at the Austin Maker Faire!The Online Metals booth was just across the way, so we stopped by to inspect their wares. They've got a great array of metals and plastics that should prove useful for all sorts of projects, and since it's all available online should make life easier for those of you who don't live right next door to a supplier. They cut everything to size, are willing to handle small orders, and even have a useful blog. Good stuff, and friendly people. We're thinking of running a contest together in the spring, so keep your eyes peeled.

I'm looking for input on the process of electroplating non-metal materials. I have never electroplated before and am open to trying the traditional method or the paint on plate solutions that are available.  I'm just uncertain where/ how to begin and what to buy. The hurdle is that the items I want to plate are not metal to begin with.  One website I read seemed to suggest that painting the object with a paint that contains metal flakes (like Liquid Leaf faux gold leaf, which contains soluble copper) would be enough to get a paintable silver plate to bond. Anyone have experience to weigh in with?  I welcome suggestions for techniques, favorite products, etc.

Hi, Please assist. I am looking for ways to create copper crystals from copper sulfate liquid by using chemicals only. I found a company in South Africa that's doing exactly that.

Hey guys, I've never really done any crafts so im not sure how to go about doing this so i figured id bring it up here. I know i'm 8 months early but I wanted to get started now, on a project for halloween. I randomly decided a few weeks ago i was visited by never good "good idea fairy" and i listened when i was told to by a unicycle by my awesome mind. Then I started riding it, realizing that i could probably get pretty decent at it pretty quickly. Then someone talked about halloween and I was thinking about what would be off the wall so i immediately though of the unicycle. Here, my mind went to steampunk, then it went to looking like abe lincoln while riding a unicycle. Then I realized that my boring chrome painted unicycle would hardly look Victorian, and that it would need a facelift. LONG STORY SHORT: My issue is that I would like to spray paint it a brassy colour, and not ruin the unicycle. I just got back from the craft store, where they told me that my idea of wrapping saran wrap tightly around it would not work because the paint would just run off. They suggested wrapping canvas around it, but when they showed me the cost of canvas i let out a faint hearted laugh and said what if i were to wrap it in a paper or construction paper type  material and paint that, but they turned that down because of the appearance it would give.  But again, it is halloween and it wont be all that light out so I dont really see a huge requirement for detail. Is there any way you guys could think of that will not ruin the unicycle?

Once again I'm browsing coudal.com and I find something interesting. T'internet says: The Portsmouth Sinfonia was a real orchestra founded by a group of students at Portsmouth School of Art in Portsmouth, England, in 1970 — however, the Sinfonia had an unusual entrance requirement. Players had to be either non-musicians, or if a musician, play an instrument that was entirely new to them. Among the founding members was one of their teachers, English composer Gavin Bryars. The orchestra started as a one-off, tongue-in-cheek performance art ensemble but became a cultural phenomenon over the following ten years, with concerts, record albums, a film and a hit single. The impact of the Portsmouth Sinfonia was considerable and their name and reputation has endured even though they last performed publicly in 1979. But listen to 'em... And the rest. E.g. Dance of the Sugarplum Fairy And Satisfaction (Stones)

I am interested in, possibly, finding a special kind of tape that can bond metal together. Where could I find such a tape? So, instead of using glue or epoxy to bond metal together, are there special kinds of tapes that could do this? Perhaps a special kind of duct tape? 

Hi, this is my first post, I hope that someone will be able to help me :) I am trying to join two motors normally found in alarm clocks, I wish to join them with a metal cylinder with about a cm bigger diameter than antenna's found on radios. How would I go about joining each motor to each end, I cannot get welding and don't know if it would apply even to such small electronics, soldering seems impossible as it won't join, any advice is much appreciated, thanks P.S The end product would look like the base of a RC car, but without the wheels thanks.

Hello Excuse me I want help in making Pulse Induction metal detector because I need in it in a minesweeper robot so any help Plz Thanks a lot

I'm very afraid of sleeping near metal of any kind, shape or form, and I need to get rid of this phobia fast. Anyone got any ideas?

These collars are found in a variety of applications large and small, this particular one came out of a broken flatbed scanner. I've seen variants with bearings on the inside ring allowing full rotation in industrial settings and small hobby ones used for axles. So, is there a name for these?

Pheewww.....SCIENCE project!!

I just got a couple designs back form the laser cutters. This is 12 gage sheet metal cut with a 2400 watt laser. Pretty cool right? It’s amazing the kind of edge it can leave behind. Just wanted to share with everyone. This is part of my ambition for putting together project kits, which help you create items from metal. Soon I’ll have a kickstarter campaign going to help launch 13 kits. These particular designs are based off of the salamander pendant and Excalibur letter opener.

I happen to have 106 aluminium right-angle triangles. They measure: 15x20x25mm Any great ideas?

I want to stick a wooden piece to a motor shaft I am not getting what glue or matrial to use. Please Help Thanx in advance

So theres this broken (battery dead) executive calculator thing lying around my house. I'm not really interested in the calculator.(Anything worth salvaging?) But it was held in a nice thin silver metal box. Measurements are.. Length 9 cm Width 6 cm Depth 0.9 cm As you can see from images there is a hole where the battery would have been changed from on one side of the box. Can anyone think of anything fun I could do with this?
