Heat shrink

This is something I've just learned elsewhere, rather than a question: that you can shrink heat shrink by holding it in the jet of steam from a kettle. I've yet to try this myself, but might find a reason to do so soon.

I've used a toaster to apply heat-shrink, but not tried a kettle.  I'd have thought 100C would be a little on the cool side...

Careful, Kim. Your sarcasm's showing...

I think it will depend on the heat shrink material (some shrink at higher temps) but personally, I wouldn't want to get loads of moisture inside my connection (if that were what I was using it for)

That worked better than I expected:

The larger piece of heatshrink was rated at 125C, the other was unmarked Chinesium.  A couple of boiling cycles were needed to finish the job.

Obviously this is a stupid idea if the objective is to keep something dry by wrapping it in heatshrink!

Yeah, the application in which someone recommended this was to apply it as heat protection on metal handles of a camping pot.

Curious about the toaster method now.

Turn toaster on, sans bread.  Dangle your electrical wires in between the live heating elements until nicely toasted.  What could possibly go wrong?

Nothing at all could go wrong but it could lead to Baldrick getting a new source of currants in General Melchett's tea cakes.

That’s better;)

On the kitchen utensils front I tend to use the little blowtorch - the bigger being more suitable for joining large copper pipe with solder

I used boiling water from a kettle yesterday to apply some heat-shrink to a zip toggle.

I was using the toaster because I was away from home, where I have a sufficiency of more optimal tools for applying heatshrink.
