Hi all,

I have been trying to pull vac on a panel in making and I can pull but not hold vac.

I started off with just a bag around the top face, edge taped, and after an hour or more of no joy put a second bag around the whole mould and first bag,

this still will not hold vac SO is it simply a case of poor bags (pin holes) or have I lost the plot!

Sometimes it can just be the way the gum tape has formed around the connector. I tend to spent a good bit of effort pressing it to make sure the seal is good.  You can also get creases under the gum tape if you are not careful.
