Can someone tell me what material I can buy that is lightweight, molds like clay, is waterproof and singeproof, and won't break the bank? does such a miracle substance even exist?

what would be a good material to use for the piston

What would be a good material to use for a piston other than pvc rod that's too expensive. I was thinking along the lines of cast epoxy or shapelock. I need a material that's pretty cheap too.

information about acrylic...

This is an excellent site, but sometimes I just want to do the simplest or thing. For example, I want to build my own acrylic display case for a model I am making. What I'd like to know: 1. where can i get acrylic/polycarbonate 2. what kind of tool are used to cut them 3. what kind of tool/glue are used to connect them basic information about common DIY materials like that. While I'd appreciate any help in replys, perhaps there should be a section (wiki-like perhaps?) dedicated to that for beginners like myself?

How to join waterproof material

Hello! First topic. :) I'm trying to make a waterproof cover out of an army poncho for the Base of my mobility scooter. I'm having trouble joining the material. I've tried hot glue, duct tape and strong adhesive with no joy. Any ideas? It's for a parade tomorrow so I'm kinda up against it. Cheers!

Semi-adhesive materials

Hi, I'm looking for some suggestions of what I'll call (out of ignorance) "semi-adhesive materials". I am looking for a large sheet that can be folded, or preferably tightly rolled (think a window blind) and a variety of shapes that can be stuck on and repositioned. I've had a look at display felt for use with hook and loop stickers. The felt is quite thick and expensive. I'm just wondering if anyone else has experimented with this kind of project. Flexible magnetic material, or some kind of static attraction or something? Cheaper the better really, but durability is a big concern too. Any pointers in directions to look would be greatly appreciated.

Any Good and Cheap Materials Out There?

I am looking for a cheap material for my projects that durable, strong, and with a nice texture. However, I cannot really find one. I thought about wood, but whenever I tried to sand/smooth it out, it never turn out right. I though about plastic (as in 3D printing), but I can't really afford a printer with my budget and since I am bound to make mistakes, I don't think 3D printing services would be good either.   What would be a good material to use that is cheap, durable, and has premium feel to it?

Patterned materials..

Trying to get  a jump on my costume this year for halloween and I want to a) plan ahead better, and b) base it on my character in Second Life. Problem is I have been looking at everything from shower curtains to upholstery materials, trying to find a solution, without much luck. Mainly due to the "best" match for what I want to try being an upholstery category material (and even that isn't.. quite right), but I have a lot of yardage involved, and it costs like $27 a yard or something... :p Basically, what I am looking for is something rubber like, so flexible, not overly "glossy", with enough thickness it can be layered, but with fairly fine detailed patterning on it. The original "suit" this is supposed to mimic looks a bit like layers of flexible armor, layered over each other, but both due to the design not being mine, and the prospect of, once done, photoing the result, doing a bit of Photoshopping on it, and "replacing" the in-world version I currently have, I want to make it slightly different. The problem, of course is that I am running into a problem of finding any material, never mind what fits the bill, save for, maybe, buying just smooth, rubber sheeting, similar to inner-tube material, then trying to do something with it. But, how, if I had PVC rubber, do I add texture to the thing (other than, for example, trying to airbursh a pattern over it, which I have zero skill at)? Nearly everything is the wrong material, too big a texture, or just.. not one that will work. Mind, best possible texture would be something like: http://i19.photobucket.com/albums/b194/Dakra/Tech256.jpg But, that ain't happening, so.. something like: http://image.shutterstock.com/display_pic_with_logo/75178/75178,1310971434,2/stock-photo-hi-tech-background-blue-metal-texture-81298300.jpg or even a very small pattern or honeycomb, like: http://images.colourbox.com/thumb_COLOURBOX2412500.jpg Would work. Heck even if I had to decal the stuff on, somehow.. But I am at a loss here as to what material to use (mainly do to finding a place to get it cheap, and not in some insane amount), and if I can get it, how to make the result not look something like the attached image, or better, add the texture to it I would like to see. Any ideas at all?

Looking for Heat Resistant Flexible Material

I am trying to find a heat resistant material that is flexible... I am trying to make a pull down shade to attach to a tension rod, that will make my home more energy efficient... This means It will also need to be thin enough to roll up into a small roll... It needs to be reflective or at least block out all the sun... I work nights and sleep through the day, and have trouble sleeping when the sun gets through...

Macro quantum effects?

A permanent magnet's magnetism is commonly described as a small molecular effect wherein the the effect of individual molecules is polarised in a way so that the effect reinforces and creates a macro effect throughout the entire material. Is it possible - do you know of any surfaces or materials, real or proposed, that could be considered to be a similar kind of "upscaling of 'microscopic' properties"?

Braided Wool Rug materials

I have the "ingredients" to make a great braided recycled wool rug: for years I saved wool fabric, bought wool slacks and skirts at Goodwill, etc, then cut them into strips, sewed them together, and pressed them into beautiful balls of wool, all ready to braid into a medium-sized (I think) rug. I didn't feel like doing the braiding part, so I tried finger crochet with the wool. That also works, but it will make a smaller rug (think several door mats). Still no motivation to finish this great recycled project. So, all this prepared fabric could be yours! You could also knit thick, cozy wool slippers. No instructions included for any of these projects; feel free to write your own instructable. Colors include navy blues, lighter blues and grays with a little red thrown in here and there. 11 balls total. Name your price, and pay actual ground shipping.

Building Touch Sensors from Scratch?

I am very familiar with velostat and conductive fabric and how to combine them to make textile touch sensors. I would now like to make a touch sensor that's more solid, and made from a firmer resistive substance than velostat. I've been looking up the resistivity/conductivity of different metals here: https://www.thoughtco.com/table-of-electrical-resi.... In theory, as long as one metal (or other material) is more conductive than the other, it should work the same? I've read on silicon and carbon fiber, but I'm not sure if what I'm researching is the solid kind, or the flimsy/squishy/bendy kind.

Material Section

Hi there!I hope this is the right section to post this in, if not then i'm sorry i picked the most probable one (i hope D: ).First of all i love instructables, i'm using way too much time in on this page than i should, but then again if it wasn't or instructables i wouldn't have this cool new Hard Drive Speaker present for this cute girl i like ;)In any case let me get to the point; i would like to suggest a Materials Section for Instructables - basically it would include material stats and an in depth explanation of the material (or component if we're talking tech here, but that's a different area). Here's an example: in an instructable, the author mentions plexiglass and that it needs to be bent. Many don't know that plexiglass isn't class, but an acrylic hardened plastic substance with abilities much like glass (but not quite). Plexiglass can fracture, but wont leave extremely sharp pieces like glass will and it can be bent when under medium-high heat from a heatgun or the like. Also that high friction (from a drill or the like) will cause it to melt.Basically what i mean here is that this section would greatly reduce the time an author spends on making his ible by letting out basic facts. E.g. instead of writing "plexiglass is..blah blah" the user would be able to look up in the materials section and read in depth for him/herself what the characteristics are for plexiglass/plywood/capacitors/batteries and so on.The materials page could be powered by the "burning questions" competition i've seen on this page. I don't think material characteristics fit in ibles because it strictly isn't - it's a data sheet that lets you understand the materials and components you're going to use in an ible.PS: sorry about the lower case i's and the occasional typo or grammatical error i'm not a native english speaker . also i really hope this is the right section to post in...

Reclaimed Wood in NYC?

Does anyone have information on getting reclaimed wood in NYC? I'm looking to do some projects with old wood but it seems like you have to order a lot of it to get it delivered. Are there any places that will let you just get a couple of pieces? If there are other people in the city that are also interested what about pooling our resources and ordering a bunch of reclaimed wood? I may be able to supply some storage space for it to be delivered and for while we sort it out amongst ourselves. Thanks!

Chinchilla-safe material for food-bowl

My chinchilla is, for the most part, a jerk. She is adorable, though, so I'll keep her. I can keep up with all of the ways she tries to antagonize me (I've come to the realization that she really is out to get me :P ), except for one. She often pushes her food bowl off of the ledge. I would move it to a lower area in her cage, but, as I came to realize the first time, she poops into the bowl when it's below her. So, I must keep it on this ledge. I therefore need a way to attach and un-attach the bowl to the cage (so I can fill it with food afterwords). I could just go and buy one of these food-bowls,  but I'm too cheap and like to make my own stuff, anyways. So I have two questions - what material would be best for attaching it to the cage, and would hot glue work as an adhesive? I am worried about her gnawing on the stuff, because I know certain things can kill her if she eats them (eg: Paint). Thanks! :)

Cheap air valves or solenoids?

I'm planning on building an unconventional pipe organ, but I am having trouble finding good cheap air valves that I can buy 60 of to complete an entire manual (keyboard). Normally, a classic organ would use mechanical linkages to a sort of air switchboard, but I have neither the time nor the inclination to build that kind of system (and I want everything to be physically robust and portable, for traveling and abuse during performances. Plus my pipes are very weird ones, and almost all of them would have to be offset anyway, so air tubes would be involved at some point no matter what.) So I'd prefer to have air lines going to each key, with a valve, and then the air lines continue to a much simpler switchboard, so that no pulleys or levers need to be involved. The valves can be electric (keys can easily connect a circuit instead of letting air through), or mechanical (pressing the key opens the valve), and my budget is about 2 dollars or less per valve. Any ideas or links? Homemade plans are welcome too, if you have a method that would be easy to mass produce and not cause leakage. Some of the lower notes may require higher airflow/larger valves too, so a solution that is scalable is preferred.

Tube Material

I started thinking about how the tube material could be improved. Although I love the ghetto look of pringles wrapped in the invincible duct tape, improvements can be made. You could use PVC or ABS for the tube, it wouldnt need pressure rating because Im sure this thing wouldnt have enough power to explode the pringles/tape team. This is rather cheap and you could just glue on an endcap. Then a BBQ ignitor can be threaded in, a ring to define the chamber and barrel and fuel sprayed in! However getting the perfect cost/durability/strength ratio is hard.

Making a plush doll

So. I'm attempting to make a Squid plush doll for a friend who's leaving for college. This is the first time I have ever attempted something like this and I was wondering how I would go about sewing the seams. Like, would I sew it inside-out and then flip it right-side-in? And is there some preferred way to sew these? Aside from that, I'm having trouble picking a material. It would be a bit large and I expect it to see a lot of use, so I want to stay away from felt. Also, I wanted to give it some character so I was thinking of making it out of polo shirts, but I have no idea if that would be a good material...Please help.

Toys/ Materials

Originally Mod Squad was born out of the idea to use donated toys to create prosthetic arms because there is an over abundance of them in the US, they are fairly low cost, they provide a variety of materials, and children would enjoy the way they look as opposed to more industrial materials. However a big concern is their durability. Share your thoughts/findings/suggestions about using toys.

E-book: Cooking Material. Could molecular gastronomy help discover new matter?

AN INGREDIENT IS A MATERIAL! Using this e-book "Cooking Material", starting from your own familiarity with cooking, you’ll find inspiration to create material from a recipe. Please watch the book trailer (if you don't see the video, please click on this link) Is it possible to make dough with sawdust instead of flour? Caramelize glass crystals like sugar? Freeze-dry a string of wool so it resembles spaghetti? Today, industry innovation has made it possible to transform traditional materials into diverse states. Liquid wood for furniture manufacture, textile spray for auto interiors, and metallic foam for experimental prosthetics are all examples of familiar materials that have been altered into new, more efficient forms. Are these “special” recipes edible? Not at all! What is their use, then? For one, disseminating the elementary knowledge of chemical-physical reactions taking place in different materials, while maybe you will discover a wall plaster or a jewelry clay or something else useful—and allow your imagination to move freely. Molecular gastronomy adds scientific knowledge to our traditional cooking savoir-faire. This science allows to explore matter through new eyes: so grab you mixer and get cooking, get experimenting!
