heat guns for shrinking elect connections

[likwid]

Too much pressure. Way too much pressure if you're smoking it. Take your time, cut slow.

You'll actually ruin the material with too much heat, remember, its just fiberglass.

Holesaws are fine, just the paint is toast.

the bigger butane mini torch works well..it is fast, but not smart where it could start a fire...The mini "pocket torch is best left for thawing door locks...

I have the heat gun Raider Ronny talks about.. it works fantastic...and is safer in builges where explosive vapors might be hiding.
