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.

Plastic Cannon??

Hi, I'm currently in Year 10 and we have been assigned to make a USB lamp. Now, I'm fine with the assignment only I cannot think of how to shape my idea realistically. I wanted to make a cannon shape, with a sphere like bottom before it curves into a thin neck. However, I don't know how to make the plastic bend into the sphere like shape. It's really difficult and I'll include a picture of my idea if it helps!

Solder with plastic?

I have been soldering veeeery small devices lately and I wanted to ask the community if there are any other cheap options such as a voltage-conductive polymer (with good conductivity), I know that it may not be possible for it to have the same characteristics but soldering with glue would be so much easier, I may sound silly but it may exist already... I found this: "silver conductive epoxy" my question still lingers: Is there a true solder replacement?

Glueing Plastics Together? Answered

When I say plastics, I mean more specifically, LEGOs. I'm glueing them together because I'm trying to make LEGO headphones, so I would need something permanent. I've heard people using cyanoacrylates and clear plumbing glue (anyone heard of Oatey?) I thought about using hot glue, but I'm not sure if that would give me the bond that I'm looking for. Would Gorilla Glue work too? Or would it be a bit of an overkill? I simply need a glue that will hold the LEGOs through enough wear-and-tear to last, and no discolouring of the pieces. And when I glue, should I glue the sides of the pieces together, or put glue around the dotted studs on the tops of the bricks? Any other glues or advice that you could enlighten me with would be greatly appreciated. :)

Plastic to plastic: "contact adhesive" or two-part epoxy?

Plastic to plastic: "contact adhesive" or two-part epoxy? What are the pros and cons of each? I need to glue two different types of plastic together, and I'm not sure if I should use "contact adhesive" or two-part epoxy. Or, I could use contact adhesive on the facing surfaces, let it cure, and then add epoxy around the edges where the parts join. I'm not exactly sure what types of plastics these are. So far the contact adhesive seem to be curing well and I'm hopeful that two-part epoxy will also work well. I'm building a mount to hold a camera to a bicycle (and plan to publish a how-to when it's done), so it will need to be strong, resistant to vibration and weather, and strong. I really don't want to drop the camera: It's close enough to a wheel that a tether could cause more immediate problems than letting the camera hit the ground. Thanks! Update: Both the contact adhesive and epoxy (separately) seem to be holding the test pieces well. It'll be another 18+ hours before I really start yanking on them but it seems like either type of adhesive would be decent. Of course, I want more than decent; I want excellent!

How to smoothly cut plastic?

I did a home automation project and I even fabricated PCB. I got a plastic box for encasing my PCB. The plastic box needs to be cut in two places to give the power chord and connection to the relays. I had soldering iron so I beat it up to a straight rod and tried to cut some plastic boxes that were lying around in my home. the heat was too much and even though the cut was somewhat accurate the heat caused the surrounding plastic to eventually melt and it became ugly. Any idea how I can cut the plastic smoothly?
