heat shrink.

[applemac]

bit of a simple question, can't remember the size of heat shrink to order to cover a crimp joint, domestic 2.5 and 1.5 stuff, had some but lost it, having a restocking day and sorting my van out as its shocking.....

cheers boys,and girls!

 

[telectrix]

big enough to slide easily over the crimp.

 

[applemac]

thanks

I did this table a while ago, the minimums are for straight undamaged cable and may be tight to fit. The table is not well formatted and you should look to the right of the column header for the relevant value. (this may change once it is posted!)

EDIT oops just reread the post use about 8- 10mm 2:1 for crimps

 

[telectrix]

i'd use 8mm coz. i'm a tight arse.

 

[applemac]

thanks mr burns your a gent

 

[dan86]

Great table I'm sure Richard, but this is what it looks like on my phone!

 

[nickblake]

Blimey Dan if you look at that long enough the room starts spinning

 

[Richard Burns]

And you can't understand that! That is what it is meant to look like!
I am shocked!

This is how it would look like just as text and that would be boring and hard to understand:whatchutalkingabout

[loplug]

what do you guys use for a heat source i had a small gas flambeaux torch that i was using but that broke and needs replacing

 

[jimmymac]

I usually use 'the fire in the pit of my stomach' or 'my burning loins'

 

[telectrix]

own up. who put the firework in jimmy's underpants.?

 

[SJD]

Cheap electric heat gun (sold for paint stripping etc.), just have to a bit be careful if the heatshrink is being applied on the only circuit available to power the heat gun!

 

[nickblake]

Normally a little gentle heat

 

[telectrix]

only reason i miss the ex-wife. she just had to breathe on it.

Antex gas cat soldering iron with the hot air attachment.

I think I'd go for number 2 Richard. I've used number 3 a couple of times and they broke quickly and were very temperamental. Cant really go wrong with number 1 though!!

A controlled gas flame is always better than a heat gun for heat shrink, especially for the internal adhesive heat shrink material. For the small stuff that most of you will be using, a simple small gas canister type torch is all that's needed.
