Ultrasonic leak finder - anyone?

I assume no one is using it? 🤔

Did you try digital absolute vacuum gauge? I find it really useful and over time it actually teaches you what kind of leak equates to different looses in vacuum. Now i get sub 10mbar every time (sub...

I do prefer a digital gauge over a leak finder, too. If you are careful with your bag the leak is always at the sealing tape. And a digital gauge helps finding them a lot quicker and much more...

Thank you all for the replies. I do have a digital gauge, but still not have enough experience to match the vacuum loss to a specific issue...

Just be methodical. Hers few tips: -Clean working space helps (i vacuum my small workshop befor applying vacuum bag) -i apply perimiter seal tape prior to anything else so it seats on clean...

I agree with everything said here about process - and the digital gauge will tell you a lot - especially about when you finally find the leak! Generally this level of awesome bagging is an infusion o...

Hanaldo, any particular brands/grades of bagging tape you particularly recommend using or avoiding? Dave

There's so many, I've barely scratched the surface. But, I wouldn't use Airtech AT200Y or GS-333T again. Just awful. My absolute favourite is Cytec (now Solvay) LTS90B. The stuff Easy Composites sel...

Thanks Hanaldo, being new to resin infusions I've been going through a really steep learning curve and had difficulty eliminating leaks I couldn't hear (pretty easily down to 30-60 millibar with a 6....

Bagging tape definitely has an expiration date, it gets less tacky as it gets older. This is one reason I like the Cytec and Easy Composites tapes so much - they start off very tacky, which means tha...

On the tacky tape thing - one tool that I really like is an aluminum roller with a handle and smooth radiused edges for rolling over the tape and pressing it down. You can make holes in the bag if yo...
