Heat Shrink Problem

[L0rdGwyn]

Just put together this power cord.  Everything was going swimmingly, but after heating the shrink with my heat gun, the shrink did not stay in position and peeled back from both connectors leaving a goopy adhesive mess on both ends.  I wasn't aware there was an adhesive on the interior.  Any suggestions for a fix?  Given that there is an adhesive I imagine that if I wanted to replace it the techflex is done for...what a headache.

Have not seen that happen before. I'd suggest getting another piece of non adhesive shrink, and shrinking that over the existing shrink and exposed glue.

Thanks Doc, I'm gonna give that a shot, picked up some new techflex too.  Do you mind telling me what the dimensions of the included shrink are so I can get a replacement without adhesive?

I’d like to know the size of the shrink also. I melted a bit of the techflex and was hoping to cover my shame with heat shrink. It looks like it was maybe 1.75” but that didn’t return anything at digiket that I could see.

It's not the size that matters  but how much it shrinks  and whether it is sticky 

Seriously though, we pay almost $50 per piece for this stuff, unless you want to end up with a whole lot of surplus, I'd drop replacementparts(at)bottlehead(dot)com an e-mail to ask about getting an additional piece.

Fair enough. I’ll drop a line. Thanks!

Shrink it down over the lumpy bits first and let that cool just a bit before working your way down the smooth part. Go slow. Less heat, more distance and a smaller nozzle help. General purpose heat guns can be a bit ferocious and it can be difficult to get just the right amount of heat where you want it. There are specialist heat guns just for this job which have heat and speed controls plus various end caps. Doc may have one but most people won't.
