Step 3Getting down to the basics
This is all you really need: the cast tube/casing/nozzle combination with the heating element in it and mains wires attached. (You may also have a small filament bulb as an 'on' indicator - up to you whether you keep it or not. I didn't). The synthetic rubber sheath round the end where the glue stick is inserted isn't essential, but stops you burning your fingers.
If you plug this in at this stage, be aware that a) it gets very hot very quickly, and b) the device is no longer double-insulated, i.e. the exposed metal is not earthed. A fault in the element may cause the metal to become live.

Great instructable. I suspect that adding the finer tip makes the biggest difference. A set of small, cheap guns with different tips would be great- like curved tips. I could use something like this in one of my electronics projects that involves filling a small cavity with glue for insulation and stress relief of tiny wires.
