FP Cable Is Not Always Suitable

The reason I was taught not to blow in a pot is because the moisture from your breath can dampen the mineral - of which would be sealed in with the compound.

LOL, would soon dry out

Shanky...are you using a cutting compound or oil when cutting....if you find this messy, old trick from an old sod...is use a candle, just as good, less mess and saves you joist blade

Or a tiny dab of vaseline

course not, I used an old musicians trick and put a bit of oil from face on first

LOL....well if it saves you blade, go for it

the blade itself had a lot of oil on it when I recieved it, tbh I tend to use 3in1 oil for everything even though I know I shouldn't.

the blade will soon get coated it that after it has been cleaned.

Joist blades, ware very quickly, if you use oil, wax or compound anything is fine...but nothing will result is 3-4 cuts, then some really bad snagging and a lot of swearing.

The reason you shouldn't blow dust etc out of a pot is because your breath contains moisture which will lower the IR test, obviously.
The moisture will never dry out after the seal is fitted, because it cannot escape.

Use a T bar, then, and a ringing tool....not an alarm for when you've stripped the right amount, by the way

You're going to blow on it (if you're daft enough) for a second or two, this will not give the insulant much moisture at all, any moisture it absorbs will disipate almost immediately.
How much residual moisture is in the air around us at any given time?

Minor problem, done thousands with a short, sharp blow. Never straight after a brew, though :drool5:

Quite a bit, try it.

The point is that as soon as you've stripped, the insulant is going to be absorbing moisture from the atmosphere. The tiny little bit from a short sharp blow is irrelevant.
I never blow on it but for a different reason

Understandable.

So what would you think the main content of potting compound is made of (oil & water perhaps), this is why ir readings are all over the place, until it drys out....!!

It doesn't dry out, it cures. It certainly isn't made from water. Once sealed, how would it dry out, how many bottles of unopened water do you see drying out?
Its not like breathing on a mirror where the condensation dries almost immediately, the magnesium powder soaks up any such condensation and would be held there by said compound - as small as it may be. In my book, blowing into a pot is just a no go when making off micc ends.
