Plastic welding

This was going to be my question about those multi packs of superglue in the pound shops.

So what is a good quality super glue.
Also is the mitre glue that comes with an activator spray any good - just the glue itself instead of super glue
.

The pound shop stuff is ok for a quick fix, but for serious stuff, I'd go for a brand name like Loctite.

Here's an interesting video by Adam Savage (of Mythbusters fame) talking about various glues and accelerators: https://www.youtube.com/watch?v=VZqf5rOJNCE

Adding pencil lead are you then actually making sort of a carbon fibre compound.

That all sounds a bit too clever.
My guess is somebody spent a lot of time mixing super glue with all sorts of stuff to see how they behaved together and what the end result was.
Definitely worth taking a look on YouTube because you'll be shown things you simply wouldn't have thought of normally.
