I recently got some thin PVC plastic for cheap.  I would like to soften it so I could shape it, but I have no idea what temperature to do it at or what to use to heat it.  I don't want to spend money.   Thanks!

Is it safe to melt polycarbonate? Answered

I'm interested in trying to do something with the dozens of old CD's and DVD's.  I was thinking of trying to melt the polycarbonate and shape it while it's  Pliable. I understand polycarbonate melts at around 150 degrees C, so it's possible to melt in an oven, but is it safe?  Will it release any toxic fumes, or does it only vent at higher temps? Also, will it deform\shrink as it cools, or will it hold it's shape? Thanks!!!

Melted plastic lamp

Hello. I found this hanging lamp at a garage sale, had to have it... Cannot find any information on this style. Looks homemade, melted plastic strips.

Melting silver to repair jewellery

Hello everyone, Iam a disabled pensioner living in Australia. I have a few pieces of silver jewellery where links have opened, and require "soldering". A jeweller has quoted me $40 each repair. I have a 3 inch square of silver sheet left over from a jewellery course I took years ago, and want my husband to melt it on the links for me. He has tried a hand held soldering iron and also a blow torch, neither worked. Please can someone advise us what else to try ? They are only minor melts required, but we cant make the silver molten in our garage. Many thanks

I Need information for melting PET plastic at home Answered

I want to melt PET plastic at home. I want to make a clear tube. I know i have to dry the plastic as much as possible to keep it clear. I will dry the plastic by exposing it to a lower temperature than its melting point for few hours. I plan to melt the plastic into a liquid and pour it into a mold. For the mold i will use 2 fire resistant pipes,and pour the plastic in the gap. Are there any hazards to this,like toxic fumes? Can i use 2 fire resistant pipes as a mold? Is there a better way to dry the plastic? If i forgot to ask something important please answer that too. thank you for the answers.

Transistors are best for melting brains!!

I have been experimenting with transistors for 3 days now, both NPN and PNP. So far I have concluded nothing. I figure the easiest thing to do is to make a transistor work as a switch. With the NPN, the current seems to flow from the base to the emitter automatically. My understanding is that current should flow from the collector + to the emitter- only when I apply voltage +? to the base, is that correct? I don’t even need to connect the collector on the NPN and current flows. I have also read a million things about transistors online. My experiments seem to disprove most(all?) of the findings. This leads me to one conclusion. I’m not doing something right. Maybe I don’t have the right transistors. I have no idea. I have been using radioshack NPN’s (276-2016) and PNP’s (276-1604) When it tried to make a switch with a PNP my voltages was going back through my emitter to ground. If I disconnected it the system(test led) no longer worked. You might need to know that I was using a 5v voltage regulator to supply a 10v 5v and ground leads for my experiments. I was getting odd voltage readings on my circuits so I put diodes on the leads. The diodes stopped my PNP from working(I figured the current was flowing odd ways…back in the 5v+?) and didn’t seem to effect my NPN experiments. So I figure I’m closer on my NPN’s than my PNP’s. I wish I could explain better but my brain is about to melt. My wife is mad at me because I am obsessed with making this work… please help :P

Homemade Electric furnace current question

Good day viewers! I recently found out about the wonders of electric furnaces, cheap to run and no smoke. I went looking around for some designs, there are some nice i'bles about it and I got very exited since my neighbours already start nagging when I strike a match, an electric furnace would be the perfect solution. I decided to go with kanthal wire, its relatively cheap at a few bucks per meter, and it can handle temperatures up to  1300C. I plan to melt alluminium and maybe some brass so I should be fine with that. now to the questions part, I have an ATX PSU with a 12V 16A output (DC), I was wondering how many (centi)meters or inches for the americans under us, it could power (if I can power it it would eventually go up to full temp right?) I am a complete nitwit at these Ohms formulas and electric furnaces, at the moment I am abstaining from sleep to build this furnace and I am sure that others are as well. I hope some nice fellow diyers can help me with it. This could be a dumb questions, maybe I need a wall outlet (230V in my place) or maybe I need some rocket science. I don't know, do you? kind regards and a thank in advance from 2 young exploramenters that want to melt some metal without ruining our lungs. excuse us for spelling mistakes, this written by non-native speakers and with shaking hands,...

How does this furnace work?

I just bought a "custom crucible furnace" from a local university's surplus department and I have absolutely no idea how to get it working. It is roughly 4 feet in diameter and 4 1/2 feet tall, it has 6 'coils' of metal attached in series with thick ribbon-y cable at the top. The side has a 'band' that sticks out but as far as I can tell it is hollow.From what I can tell it might be an arc furnace that something blew up in and damaged a bunch of the components. I really want to get it working as I've been saving aluminum cans for a long time and scrap metal so my plan now is to just hook up the cables to my arc welder and see what happens :) but if anyone knows anything about it or where I can go to get more info that would be much appreciated!

Heating options for hot bueing steel?

After moving house I am still living in a big mess of boxes that need to be unpacked, kitchen stuff be sorted and and so on... But with a big garage and proper workspace at hand it is also time to consider my options on how to create my tinker space. I would like set up a small forge later on if the landlord gives permission and that means bot blueing steel again. Which brings me to the problem of heating the nitrates :( My last setup was not only on a different continent but also totally oversized and powered by three big gas burners. This time I would like to go a bit smaller so I can use it inside the workshop. Was thinking of a max of around 8kg of nitrates that need to be heated in a safe way to melting point. Problem with that stuff is that it is not only highly corrosive but also requires quite some time and energy to melt. Using gas on such a small scale seems far to dangerous uless I include baffle plates and add several safe guards, so I would like to avoid the open flame approach here. Only reasonabe alternative that comes to my mind is electric heating. Did some small test last night outside :( Used a 2000W electric hotplate and an old stainless steel pot with about 1kg of nitrate in it. After 40 minutes there was still no real melting happening despited the entire thing padded and covered in glass wool. 20 minutes later I turned it all off and once cooled I found that only about 1cm of solid nitrate was at the bottom. If I would use a suitable container of let's say 20x10x10 cm as a small melting vessel: Could it be sufficient to use a 2000W nichrome heating element (with temp controller of course) in an insulated, forge like setup to melt the nitrate ina reasonable amount of time and be able to keep it that way once the steel is dropped in? Problem is the entire garage is already setup with power outlets and they all go to a single 10 amp breaker. I could max it out with 2400W but for obvious reasons would prefer to have some juice left for lights and other uses. If anyone here already made such a thing it would be great to hear how you solved the heating problem without waiting half a day for the stuff to melt.

Soooo... How 'bout that Cubic Zirconia, eh? [Most Likely DANGEROUS]

So I was just browsing Wikipedia when i fell upon the page about Cubic Zirconia. It turns out, that the basic principles of synthesis don't look all that complicated. So I was wondering, if anyone knew of any plans for a small skull crucible that were floating around the net.. I probably wouldn't use it for zirconiua, seeing as it needs around 2700 degrees Celsius to change structure (this is the dangerous bit), but it might be a fun introduction to induction heating. Also, it's a pretty awesome way of eliminating the need for a refractory when melting stuff (keeping a solid layer of the material as a shell instead). I think I could build most of the parts, but i don't know what frequency, how many windings and such would be needed for the coils. Also, if anyone knows of any other risks than the obvious burn hazards, I'd be thankful if you'd tell me before i go off and get killed trying to make this. Let's discuss! :D (Also, Skull Crucible is just about the most awesome name for anything ever).

Heating Element for DIY Melting Point Apparatus

Hi Everyone, this is my first post on this site!  I am seeking advice to help me construct a home-made melting point apparatus (M.P.A).  A melting point apparatus allows it's operator to determine the melting point of a chemical sample by heating it in a controlled fashion and noting the temperature when the sample melts.  I have most of the design made up in my head, but I'm not sure as to how I can obtain the proper heating element.  The heating element I am seeking is an emulation of the M.P.A.s heating elements in my school's chemistry lab, which look like this: a metal block (about 3cm tall by 2cm deep by 3 cm wide) with vertical holes bored into the face with a pane of glass pressed against said holes so a glass capillary tube (containing the sample) can be slid into the bored hole and viewed through the glass pane as the sample is heated by the metal.  Another hole is bored into the metal, adjacent to the sample hole, for a thermometer.  So again, my question is do you have any suggestions as to where I could by a heating element like this?  Or, any suggestions on how to build one?  I have a jewelry shop at my disposal so I can probably bore any holes myself.   Any suggestions will be appreciated, thanks!
