Remelting Plastics

Has anyone experienced remelting plastics from around the house/recycling bin in order to cast objects? After reading about the backyardfoundry for aluminun and such, I realized that I'm much more interested in plastic and casting plastic parts and art things. Also, it could be cheap and plentiful. I have the moldmaking knowledge for aluminun and bronze but want a plastic medium for the casting material so I can work at home/backyard without the foundry equipment.

Etching, staining, or wildly coloring plastic

I own too much plastic, that I use regularly, but want to decorate. Is there a SAFE method to chemically or otherwise "mottle" plastic with colors? Not looking to use paints, as those will just peel off. I know that plastics react to some solvents and such, but is there anything that you could 'wash' plastic with that would just outwardly alter the appearance? If I could get an "oil on water", or even just a "camo" sort of effect, that would be wonderful! (I tried searches for what to AVOID using around plastics without risking such an effect, but can't get the right search parameters...) Thanks for any ideas! I'd really prefer not to have to throw stuff out.

Plastic Part Needed

I am looking for a plastic part and have searched all over the internet for it and cannot find it. To give you a visual of the part, its looks just like a plastic pizza box support but its height is about 6 to 8 inches. Has anyone seen anything similar to this description? Thank you for your responses. Chris

Glueing Plastic Syringes

Hi. Most of you know the plastic medical syringes  (Terumo is a popular brand).  They are made of a plastic that I have not yet found a glue to work on. Can anyone offer some suggestions? A list I have tried includes Contact cement,  Super glue, Bostic Vinyl cement,  Sil-poxy, Epoxy-Resin 2 part (Araldite) So we are moving into the area of the exotics Many thanks Dave

Looking for a plastic etching or scribing kit to place my name on sunglasses so I never lose them again!

Hi, Does anyone know of a way to imprint my name in ordinary plastic objects so I can identify them with my name and phone number? I have a metal etching kit, but I can't seem to find anything similar with plastic.  I know that I can scribe it by hand with a dremel, but I want something more regular and 'pro' looking than that. Thanks, Blake

custom ruler scriber

Years ago (before computers), I worked in a lab where we were called upon to make clear plastic rulers with precise increments.  We had a simple machine to accomplish the job. It was an ingenious gadget that held the plastic in place and with a turn of a crank, it moved the plastic a set distance and simultaneously scribed the plastic with a metal point.  The precise divisions could be set with a dial and all you had to do was turn the crank. Has anyone ever seen one of these machines?  If so - what is it called and how would you make one?

Who I can unclored plastic, colored in the mass

Hi all ! I want uncolored plastic, or uncolored latex, and I need to know how it's possible. For have light color, pastel color. Like nightblue => lightblue. It's used for cleaning old yellow plastic, like old white or grey computers or consoles, but it's maybe only for have the origin color, not for uncolored the color in the mass. It's yellow because the plastic is oxyded. With hydrogen peroxyde + UV. So, do you know if this combo is good for my project ? Or who I can make it ? It's for custom parts. With many friction, and it's bad to use paint for that. Hope yoou help me, see you soon. Thanks in advance.

Assortment of plastic gears for sale. 70 in total.

I have an assortment of plastic gears all different sizes on ebay if anyone's interested. Mostly from old printers and scanners. The item is in the UK, but willing to post to most countries. From the listing "This is an assortment of plastic/nylon (not sure what they're made of) gears that I've collected over the years. These are mostly from old printers and fax machines that I've stripped for the stepper motors. Please bear in mind that most of these will not mesh with each other - they're all different sizes, pitches, and different centre hole diameters, and many of them have original grease on them. So don't expect to be able to make a large gear train out of these, most of them won't mesh.";=290634418757 The ruler in the picture is 20cm ( 8" ) long

why am I not in the contest?

I don't understand why my instructable, the sphere lamp, isn't in the coffeecup contest anymore. Is it because of the use of plastic cups? Because as I mentioned it was intended with paper cups but I didn't had those available. If so, why didn't I got the message about disqualification at first and are there other instructables in the contest which only have plans about using paper cups but no cup was used? Will it help if I rebuild it with paper cups?

painting a lawn flamingo

I am trying to bring back the pink quality of several Yard flamingos.  I know I could buy new ones, but certain people would rather keep for sentimental reasons, so I am trying to restore them.  My problem is when they are painted, after a period of time it chips off, I believe it is because the paint cannot deal with the flamingo plastic swell and shrink of the heat of the day and the coolness of the night.  Any ideas to extend the paint's life, would be appreciated.

Lexan. Just to be sure...

So, I was thinking about an Halloween mask, a steampunk diving dress. The most complex thing is, of course, the head piece. More specifically, I'm in a bit of a quandary with the visor: I need to make a convex, ellyptical dome of clear plastic. Since I need to fit that into a frame I need to make it from flat panels; this way I'll get the shape I want. I think I'll use Lexan: it seems to be quite sturdy and easy to work on. In theory, all I have to do is heat the thing up to 200°C (400°F) and it will bend like a charm, but I'm a bit worried about exalations and whatnots; can someone help me here please?

1.5 Litre Waterbottles, Lots of them.. what can I do with them!

Hi there! I live in an area that I've got to buy bottled water because the water here isnt so good. So every week I go through like 12 bottles of water. We have recycling, but going down to the recycling bin every couple days is annoying. So I figured that there must be something I can do with them. I can do planting and such, so I'm looking into that. But in reality I cant plant 300 different plants! So what sort of things do you think I could do with all these bottles?UpdateThanks for the comments guys (gals)! Some of these ideas are really really good! I just either (a) lack the lake/body of water to build the rafts (b) have no desire to launch myself into the air (c) or live where it doesn't rain....Either way, I love these ideas. I thought this topic got buried! THANKS!!

Cut Plastic bottle in half, then reattach.

Heyah, So yeah....for a project i'm working on I would like to cut a plastic(coke cola) bottle in half, then put some stuff inside, reattach the 2 half's together, then fill it with a liquid.(Don't ask) My first attempt I used hot glue, but sadly the plastic is super sensitive to heat it would seem and it just simply melted the plastic so I wasn't able to seal it.  I tried to even let the glue cool down, then apply it but that didn't work either. Any ideas?

PLastic to oil converter

Hello, One year later, I found that video on youtube about a japanese scientist who converted plastic back to oil : Source : I waited for a convenient version for home use but still the smallest system weight 50Kg (100 pounds I guess). For what I read on the subject it's a kind of catalytic pyrolysis (whatever it means for such a non scientist as myself...). As any of you have an idea on how to make this kind of system for everyday use?

Plastic Vehicle Body

Hey, people. I'm not sure if this is the right place to ask questions about this sort of thing and I can't find anything on the web on the subject. I guess not too many people want to build a vehicle body from scratch. Anyhow, here's my situation. I have a large mobility scooter which I would like to transform into something nice for a Halloween parade. I can't do anything too fancy or professional looking because I don't have the resources for something like that. What I think I'll do is build a frame over which I'd bolt sheets of plastic that are cut in particular forms. Then I'd paint the whole thing with spray paint and touch up with an airbrush. What I need to know is which materials to use. There are all sorts of plastic out there. I won't be forming anything with heat, so at best I'll only need plastic that's not too thick and has a good surface for painting. Also, I don't know what to use for the frame. If you don't know about the materials, any sort of advice or encouragement would be appreciated. Thanks in advance!

New Light Fitting Smells Of Fish When Hot

Hi, I have just fitted a new light fitting. After it gets hot (60 Watt filament bulb) The room smells of fish. I believe that the smell is coming from the hot plastic, probably from the plastic that holds the shade in place. I don't want to reduce the wattage, The label on the connector says it is rated for 100 Watts. How can I get rid of the fish smell? Thanks

Squishy plastic lava thing

Remember these squishy things? You got them cheap at toy stores and were always suspicious of them breaking and spilling their noxious contents all over you and your family (at least, that is what I worried about as a kid.) I think I had a cd case with purple blobs of liquid. Anyway, I want to try making something like that, though I haven't done anything like it before. I suppose I need your help with ideas for 1. what would be a decent liquid filling that wouldn't degrade or get moldy or fade somehow 2. how I would go about sealing the edges in a aesthetically pleasing manner. I suppose there is heat sealing, and glues that bond plastics? And...I guess I would not be able to make very complex shapes??

Plastic Bottle Boat Set to Sail Pacific

Talk about keeping the bottle - how about keeping 12,000!David De Rothschild is currently building a sailboat from 90% recycled materials, which he has dubbed the Plastiki and plans to sail from California to Australia! Joining him on the Plastiki will be a permanent crew of three sailors and scientists plus a handful of other crew members who will rotate through the voyage. The Plastiki is expected to stop in Hawaii, Tuvalu and Fiji on its way to Sydney, a trip estimated to take more than 100 days.The vessel's twin hulls will be filled with 12,000 to 16,000 bottles. Skin-like panels made from recycled PET, a woven plastic fabric, will cover the hulls and a watertight cabin, which sleeps four. Two wind turbines and an array of solar panels will charge a bank of 12-volt batteries, which will power several onboard laptop computers, a GPS and SAT phone.The plastic sailboat is taking shape in an old pier building not far from this city's famous Fisherman's Wharf and is scheduled to set sail in April.Read the whole story at CNN's Tech spot.

Where can I buy corrugated platic sheets (Coroplast?)

Hi. I recently was working on an art project and realized the material I desperately needed (after many others failed) was clear corrugated plastic sheeting. Apparently the main manufacturer is Coroplast. I looked around and only could find places selling large quantities. And I mean LARGE, more for structural projects than craft ones. I'm just trying to find a place where I could get a few sheet of clear 24" x 24" sheets. Does anyone out there have any suggestions?

Creating a light from recycled parts

Here is my dilemma. I have a Superman acrylic plastic emblem. I removed it from a former toy and now I have an idea that I would like to make a light out of it. As you can see by the photos, it's not very big. It's length is roughly 2 inches, and I plan to sand the ridge down so it can slide inside a PVC pipe adapter. I have a landscape capsule light, so it doesn't have excessive heat, and it has direct light. I am trying to figure out a way to use all the material to make a light with a Batman Signal light type stand. (See Instructable for the the Batman Signal light) If anyone can assist me or give me some ideas, hints, suggestions so I can put all this together, it would be terrific. I will post the whole thing when I am completely done. Thanks!!!
