Semi-Solid Material? Answered

I was hoping anyone knew of or had a good suggestion for a material that fits my description. Either a rubber- like material that was softer (more malleable) than rubber, but tougher to prevent tearing or a putty-like material that would change to a firm solid when heat or a current was applied. I need something that can be molded to a specific shape and then hardened to hold that shape, but can later be returned to the non-molded shape.

What is a good material for a rorschach mask that i can see out of?

Hi, I soon am going to make a proper animated rorschach mask, ive aquired all the materials i need except for one thing, the actual mask components. I dont know what material i should make the mask from, being as i am using thermochromic pigment suspended in acrylic base, im not sure if spandex will work, also, i have no idea how clearly i can see through any of these materials. What good would a working rorschach mask be if i cant see out of it. The way my design will work is numerous heat pads linked to a controller, the heat pads will heat up to around 40 degrees , just warm enough to get the pigment to change from black to clear, and essentially thats how ill change the mask pattern. ill have 2 masks in a sense, one is a thick balaclava on which the heat pads and wires will cover, so they arent right on my face, then a secondary mask will go over that, though when done they will be attached together.  the secondary mask will be white and will have the pigment on it, it doesnt need to be particularly flexible as the mask will retain most of its shape anyway when not being worn, i just need to be able to see out of it, my design wil lalso include a breathing and cooling system so i dont activate the pigment with my breath, or fill the mask with sweat as it cant be washed. what material should i use?

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?

Laser cutting a spring - choice of material? Answered

I have a scheme that requires a flat, non-conducting spring. Acrylic it too brittle for my needs, but I know that some plastics can, when cut with a laser, give off fumes and gases that will damage the laser cutter (eg PVC gives off gases that will cloud the mirrors). What materials would you recommend? (I've attached a quick sketch of the general shape of the planned spring.) EDIT: I've added a rough sketch of the project - a torch, cut from acrylic. The four projections are to bind it together with an elastic band.  The switch operates like a syringe.

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.

I need help selecting a type of heat-forming plastic. Can any plastic experts offer advice? Answered

 I'm nearing the end of the design phase of a project, and I need some help selecting the right material with which to make it. I'll essentially be building a solid, 3-dimensional form, and mass-producing plastic pieces by setting a plastic sheet over the form and hitting the plastic with heat (probably a heat gun), and then trimming. I would prefer a plastic that is food-safe. Are there any plastics that would "droop" onto the form when heated, but stiffen up again properly when they re-cooled?  A pliable, but still fairly rigid plastic that resembles the stuff those cheap black plastic oil receivers are made out of would be ideal. If this type of plastic exists, where would I get it? I wouldn't mind buying it in reasonable bulk, because I may be selling the end product. Thank you guys in advance.

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...

I love the idea of using material that would otherwise be thrown away, and it's cheaper :). I need a fairly rigid area of about 25x28cm for the "shelves". The material will be in view, so it would be awesome if it looked interesting. The actual structure of the rack will probably be MDF, so I know for sure it will not fall apart. Plan B is using VHS tapes for the "structure" (vertical parts) and wood for the shelves, but that would probably be harder to pull off :)

Materials question? Answered

I know it is possible to by "flexible plywood" or "flexible MDF" - sheet material that can be rolled up in a single direction, whilst remaining rigid in the other. However, I have only found versions that roll with a minimum radius of about 15cm / 6". Does anybody know of a similar material that can be rolled with a much smaller minimum radius, say only 5cm / 2"? It doesn't have to be wood, any easily-worked sheet material will do if it can be rolled in one direction whilst remaining rigid in the other will do.

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.

Which brings up another question does anyone happen to know if this stuff is safe for those kinds of applications or is it similar to fiberglass insulation which is actually pretty harmful to touch?
