HH Meter V2 It Works !!!!!

Looks good to me.
That's the thing about pressure-testing fabrics: you tend to get a bit damp …

Interesting that you got micro-jets almost before you got small leaks. But the measured HH looks better than some of the stuff around. Details?

Cheers

yep its an outdoor sport for sure :)

I had the three bubbles,
then pushed if further,
removed the bubbles with a tissue, and then the jets appeared,
maybe the surface tension of the bubble held the jets back ?

those winter nights will fly by :)

the fabric used in the test was this one as my standard

Great job Gary!

Hey Gary,

Can we send you in some fabric pieces to be tested?

I would hate for you to have to buy a bunch and spend an unnecessary amount of money for what many of us have multiple of laying around.

Nice job!

i have loads of fabric waiting to be tested,
But if you want any tested no problem, I am in the UK

As its home made i cant guarantee the accuracy
But it seems to be pretty accurate with known fabric matching to spec.

The testing needs x3 15cm square pieces of new fabric
Then I can do abrasion and folding tests as well.

I know the other chap on here can give you formal testing.

:)

Gary….I believe the person you are referring to is Richard Nisley an excellent person to contact.

yes thats the chap i believe he can provide professional testing
:)

Gary,

I believe you have just raised the bar for myog projects.

You've given me the confidence to resume work on my myog time machine.

Cheers,
I am swamped with flux capacitors if you need one :)
