[sdiy] How do you shrink heatshrink...

[Julian]

And another question...

Heatshrink.  Whats a good way to shrink it.  Im running it along some cables
of about 40 cm in length.

Probably a heat gun is the best way, but i dont have one.  I can probably
get my hands slyly on a hairdryer.  In the days my mom attacked me with
them, i seem to remember theyre pretty hot?

Oven?  What temp and how long? Preheated, i assume...

I dont want to melt the rest of the part, so...

Cheers, Julian
