General Construction part1

Vince, Here's a few more pictures that I think are not in the instructables. The machine is at the college. I'll try to get some more pictures of it Monday. I see your confusion we need an end view of the Y rail showing the X stage mounted. I also made a 3D google sketch up of it that would be real handy. If I can find it.

Foam Mascots

Hi, I'm researching ways to make a foam mascot. My main problem right now is trying to find places that sell large pieces of foam, like upholstery foam or some kind of polyfoam. I've been looking through a few cosplay resources but haven't really found any good ones that deal with foam. Does anybody have any experience with this?

Help needed

I have been working on something quite big.  I prefer not to say what it is(i will however, unveil the finished item on instructables and show people how to make it). What I need is a light, strong, and hopefully inexpensive foam. Any suggestions on where I could buy some or how i could make some would be much appreciated. thanks -Burn

working with closed cell foam

I am making a clown prop. I have a pair of dry wall stilts that I have attatched closed cell foam to and carved into the shape of bare feet. It was my entent to coat the foam with liquid latex for durability. The foam when shaped and sanded left undesirable open pores, I next filled the pores with flexable latex caulk and then started coating with the liquid latx. I am not happy with the results I am getting, the foam is still to bumpy and the added weight of the caulk may be a problem. I am contemplating starting over with another product. I know that foam board used in the housing industry would be easer to sand smooth, and is there a differant coating that would be easer to apply. Thanks Rick "Locco"

Costume foam

I am make a cosplay costume and it's VERY large and it requires a foam I have been looking all over trying to find anything about it. http://www.youtube.com/watch?v=4NsQLq7EMkk At the 3 minute mark it shows this man making a Halo Elite costume leg, as you might have noticed the foam is ridged but flexible, also it's large. Where can I buy foam like that? I am assuming I can't buy it in such a massive size and that I would have to glue layers of it together, but if you know where I could buy it in a massive size that would be great too.  Final part what would be the best way to cut the foam it looks like that man is using a turkey carver any other ways? Thanks to all those that can help me!

Easy spray/liquid *open cell* foam?

Hi all - new here  :)  I was trying to think of where I could ask this and I immediately thought of instructables.  Does anyone have any ideas where I could find a spray or liquid *open cell* foam?  It's easy to find cans of spray closed-cell foam these days, but I've never seen one for open cell foam.  I've done a lot of searching, and the only open foam cell solutions I find tend to be giant expensive things for insulating houses in bulk, nothing for small scale applications.  I'm looking to fill a bundle of relatively fine tubes (diameter TBD), which I want to act as a sponge on the inside, resisting allowing the liquid inside to drain out while still allowing for gas migration.  Hence closed cell is not an option.  Polyurethane is probably fine, although other materials may well be fine as well. Any ideas?

Need Advise on Building Large Arch Gate

I am trying to make a large arch-like gate out of foam. It would be about 8' high, it would have to stand on its own, it would have to be able to be broken apart into pieces and needs to be able to last in the elements. I was thinking of buying wet foam blocks (foam used by florists) and binding sets of them together and using spray foam to cover the outsides and paint it grey to make it look like rocks. It would be held together with dowels through each set of foam and have an anchor at the bottom using dowels hammered into the ground.  Inspiration for this design came from the vault from the Borderlands game series  http://i.imgur.com/DwMSsWb.jpg I wanted to know if anyone has seen guides for making a fake stone arch or if anyone had ideas for making this (Especially if the ideas aren't too expensive) Thanks

How to insulate a cooler box

I have just bought a plastic cooler box. It is two boxes in one: an inside lining, an air cavity, the outside case and  of course a lid and handle.. I would like to improve the insulation. I have a 750ml can of expanding polyurethane foam which I thought of spraying into the cavity. It will dry in an hour. I can work out the exact volume  to be filled with  the foam by prefilling it with water and measuring the amount of water that pours out of the cavity , but I do not know the best way to apply the foam. Any ideas, please. For example should I wrap the inner box in anything before pushing it into the wet foam that I  spray against the inside of the outer case? Robin

I'm stumped

Hey everyone, I can't take it anymore! At my workplace, I work in the shipping/receiving department...all kinds of new and strange packing materials come in. We generally are able to re-use things like the bubblewrap and boxes, but there are some things I just don't know what do do with, and I feel horrible throwing them away..Maybe you guys can help? We get ALOT of foam, all shapes, sizes, and textures, and I have no idea how to reuse it...then we also have these long rectangular tubes that hold electronic chips in them, however when they get to us, we take them out and put them in bags, so we no longer need the thin tubing, do you guys have any ideas? I've attatched photos. Thanks! Lita L.

Where to buy polyurethane resin/foam in UK?

Hi guys, Do any UK people know of nice suitable places to purchase the two-part polyurethane resin that mix together for making casts from moulds? Or the polyurethane foam that expands a bit when it cures? There's two places on eBay (TOMPS and another) but at £24 a kg with high postage costs, I was wondering if there's any bricks & mortar places I can pick it up, or other online places to buy the foam? I'm using it to thicken the shell of a Pepakura helmet so there's stuff to sand down. Any pointers please?

Make your own "Memory Foam"?

Can we make our own "memory foam"? I'd like to buy "memory foam" in a spray can - but I don't think that product is available. I was hoping to find something like "tempurpedic" in a spray can.    I'd like to replicate the really soft top layer as seen in those mattresses. The "great stuff" foam spray cans come to mind.  However, the end result of those is not a flexible soft foam. Would like to fabricate my own custom foam inserts with the material.  Any ideas about making or sourcing materials? Thanks!

Foam Board/Cardboard Shoes

Hey, I was walking past my little sister watching PBS Kids and on one of the shows this girl was trying to make her own shoes. Out of cardboard. Lightbulb. The only reason that they didn't work is because they got waterlogged. I am thinking that with good enough sealing and strong enough glue, useable shoes made from cardboard are a possibility!The only problem is that I don't have foamboard or time to spare or a working camera at the moment. If anyone could carry this idea further than me, have at it!

Recycling fabric into fillingmaterial. Can it be done? And how?

Hi there, This is something I've been wondering about and maybe you'd like to share any ideas on the topic. Thing is this: There's two things I use a lot: Fabric and fillingmaterial. I mostly use Fiberfill for the best results. It's smooth, springy, soft and light. Great stuff. However for big projects it's costly. Now I also use A LOT of cheap fabric. After cutting it a lot of spare pieces remain. The bigger ones I can still use but the tiny bits (like in the picture) I throw away because I have no use for them. And I feel bad about it, because it seems so wastefull. I hate wasting things. So what I'm thinking is this: is there a way to grind the spare pieces of fabric into filling material? Offcourse, I could just take all those spare pieces and use them as filling materials as they are, but as they lack the springyness (not sure if this is an actual word, sorry if not :) of Fiberfill, the result is bumpy and heavy and you'll need a LOT. Now there is a cheaper alternative for fiberfill, I think they take foam matresses and pulverize them. It's a bit springy but still heavy and extremely messy to work with. Now for those spare bits of fabric: - What would be used to grind them? - Is there a way to somehow bind them, so it becomes a substance simmilar to fiberfill? Like gelatine, but for non-edible purposes? (grind'em, bind'em) I have no idea if this can be done (at home) but if you have any ideas I'd be happy to hear them. I think a lot of people would be happy with an inexpensive, recyclable filling material!! Material for a great instructable if you ask me :D

Lost Foam?

Hi guys, I've been messing about with lost foam aluminium casting here in the UK. I've tried packing expanded polystyrene, and Jablite but they seem really difficult to get a good finish on the foam patterns. I want to be able to machine them, or use them in a basic foam lathe. I know that in the States they have a denser finer grained insulation material (blue and pink in colour). These both seem to be better for obtaining surface finish. I've tried to Google the stuff over here but it seems to be silly prices. Does anyone have any links to UK sites that sell a similar product? I was wondering if the harder stuff that you saw up and stick between the rafters for loft conversions would work as this seems a much denser fine grain foam to me. Any ideas or advice would be appreciated.

FSR - Conductive foam readings

Hello! I am making a prototype of a force sensitive resistor, and i am using, to old 97%kobber coins, metal sheet and a tiny piece of conductive foam that i got from a tv-repair shop. The setup is not very good, but its a start, and i am planning the next move for better results... Now... I want some decent understanding of how the readings work, and why I get these results.. First test, are written with black, and and as you can see it, has the same amount of space between 0-1kg and 1-2kg, but 2-3 and 3-4 changes to a very small space? Why is that? Second question is, that i have used the x10, to read larger forces. 0-2,5kg and 2,5-5kg has same amount of space. Will the space decrease too, when getting further up the scale too?  - I know the conductive foam has its limits too, but just to be clear of my readings. Thanks in advance! I hope you can see the readings on the picture..!

Aluminum Foam: A new age material for people

So i thought i'd start a thread on Metal foams. For those of you that don't know what it is i offer the following links: http://en.wikipedia.org/wiki/Metal_foam http://www.metalfoam.net/ Looking through the forums, I figured this could be something pertinent to a DIYer's interest, since metal foams, specifically Aluminum foam, is strong, light, and relatively cheap. The fact that it marries with advanced composite materials science is kind of an added secondary bonus. I'm personally interested in this sort of stuff because i want to make an ultralight aircraft and this stuff could be used to accomplish that... but that's sort of something that's tangental to most that'd find info on Foamed Aluminum interesting.

Flexible Urethane Foams

So I was looking for a way to make a new seat cushion for my car (driver's seat is starting to decompose). I was looking for a memory foam or some other flexible pour-able foam.I came across this: http://www.smooth-on.com/foams.aspI also contacted smooth-on for advice on what density foam I would need for a seat cushion and bolster (from inspection - the factory seat cushion was made from a pour-able foam cast in a mold).In any case -- just passing this info along. Not sure if anyone will need or use this - but I keep a list of suppliers just in case someone I know is looking to do something ;) If anyone else knows of another supplier -- let me know. I probably won't go this route ($100+ for 1 seat cushion is a bit steep) but it may be an option :P

We used a low temp hot gluegun to put it all together, then coated the parts we wanted to look shiny with polyeurothane.This type of foam accepted spraypaint well, it didn't eat it at all as it would with styrofoam.

Toxicity

Does anyone know how toxic the foam inside a refrigerator door is (Urethan foam?)? Is there any danger in coming into contact with it? All I can seem to find online is long-term effect of the foam on the environment (which are apparently very bad). In short, should I cover up the back of the door and never think about again, or can I remove it from the door with a chisel without much worry? I want to remove the foam because it looks a little moldy on the top. Any suggestions? I'm making a magnetic bulletin board for my wall in case you were wondering. thanks, Randy

DIY foam board to build castles. Needc help for drawings.

cant get my foam cutter to work.

Ok im building a foam cutter, kind of following the instructions from https://www.instructables.com/id/EK8Q92824BEP286S6S/aaand it doesent work. i have a 10v 5 w transformer attached to a metal frame that holds the wires. and the transformer is attached to this stainless steal wire. i was thinking that maybe because i have it attached to a metal frame it sucks all the current but technically shouldent it try to "find" the thinnest place to short circuit and heat up? When I touch the wires to the frame it sparks up, so there is a current going through. And also if I just hold a piece of wire on my hands and connect it to the transformer, it doesn’t heat up either.sorry no pics, i might have some in a couple of days.helps! or suggestions as to what the reason might be for it not working. i am trying to build model for school, alas i think the foam cutter itself is more of a project then what im building

Potential $5 RC Hovercraft

Hey y'all, I was bored, so I made this RC hovercraft, kinda like a Tiny Whoov, from the guts of a $5 RC helicopter (sold at most FiveBelows). The idea is that a hovercraft is more fun than a cruddy helicopter, in addition to being a fun and easy DIY project for the weekend. It could be a nice gift to a kid. My first concern was that the motors would not provide enough power to get the thing moving. They give more than enough power, and this thing can MOVE. My second concern is that the differential thrust steering system (one motor turns faster than the other, steering the hovercraft) would not be effective enough. This is still a problem that I don't have the enthusiasm or time to solve anymore. Maybe someone could figure out how to reprogram the FC board to have more differential thrust (is that possible?), or somehow configure a servo or actuator without raising the cost of materials too much. Anyway, here's the concept, go have fun with it.Supplies:Foam platesHot glue$5 RC helicopter with 2 motors and receiver (LED optional, but really cool)Connector (the battery might be soldered directly to the FC board, so this will make it easier to fiddle with)Soldering iron (not %100 necessary, but it can come in handy)Propellers (see design notes)Design notes:Notice how the underside of the hull is curved and smooth. I used propellers from a Blade Inductrix FPV Pro, but any micro quad propellers should work. Notice the nice little compartment under the FC board where you can stick a battery without the need for Velcro or glue. This would be a very easy FPV mod, but that would add about $20 to the cost.

Back to the Future Part II Nike Shoes

Sup, everyone! So the idea I had was the nike shoes in back to the future part II. I got to thinking that it would be really cool if i could make a pair, so i looked around and found that nike had already made a pair back in 2011, it looked to me like they used reinforced foam. So then the next thought i had was get on instructables and get some ideas from you guys. The basic idea I have is to modole them out of strong foam, i'll probably make a cardboard mockup first, then line it with fome and material. after that I'll probably get some really stiff foam then make the outside out of that an probably make the sole out of rubber. Please share your ideas, thanks in advance

It then proceeds to rough it off into layers, it then adds a more defined smooth layer.To top it off, it then coats the entire thing in a epoxy layer.The entire process is both entertaining, and hypnotic.Via Makezine

Making new bench seat

I need to remake the rear bench seat for my boat. The old one is about 100lbs and I would like something a little lighter. I can make a new frame with aluminum, but I am stuck with what to replace the cushions with. Whatever foam they are using is super heavy as well. Is there some way to remake the seat with styrofoam beads beads or something and still maintain form? I considered making a cheap gel seat using a thinned out mixture of silicone, but that wouldn't be any lighter than the original bench and would likely be heavier, actually. I think foam beads would work pretty slick.
