Here's a really simple way that you can do some plastic welding with weed eater trimmer string and a soldering iron

Step 2: Make a little hole

make a small hole to hold the rivet that will join the two pieces together.

you can use a drill, or if you are using plastic, you can use the soldering iron

Step 3: Make one side of the rivet

feed a bit of trimmer line through the hole.

using the soldering iron, mash the plastic down around the hole. If your soldering iron has a low setting, try that first.

Step 4: Complete the rivet on the other side

Step 5: A light duty bond but it works

the rivet holds pretty well, but can be torn apart with a bit of effort.

would this be possible with plastic barrels, welding them end to end?

I think you would need a stronger plastic to rivet with in that case... Not sure, let us know how it turns out
O.K I'm just going to publically announce, that I don't know what a rivet is. There, I did it. Please be gentle with any response. I also don't understand what the finished product is and how it works. Remember, there is a "be nice" rule people pulleassssse

Oh yeah, I guess it's not very clear. That thing I was working on was an instructable that didn't work out. So I never did publish that or explain what it was. The general point of this instructable though was the discovery that I could make plastic rivets out of weed whacker wire. Rivets are just something that can hold two things together. Usually they are made of thin metal pipe.

Ahhhhhhh I get it. Tx 4 for explaining :0)
good idea
