Hi guys, 
im quite new resin infusion, im having some trouble getting the bag to stay sealed! ive tried everything! 
key points:
- the mold and layup is inside an envelope bag
- all equipment and consumables used is from Easy composites and made for resin infusion
- masking tape the edges of the infusion mesh to avoid small holes in the bag
- wrapped the edges and underside of the mold with breather cloth to avoid getting holes in the bag
- peel ply ontop of the spiral hoses
- checked the hose connectors and sealed them with bagging tape
- tested to make sure the catchpot is not leaking
- tested to make sure the pump isnt leaking
- used a stethoscope to listen for leaks - no leaks found!

ideas:
1) i have read that double bagging could help? putting the whole thing into a second envelope bag, then pressurizing the second bag? is this the right process? 

2) its a small part so instead of double bagging, maybe i can put the whole thing into a vacuum chamber? (my degassing chamber, with the addition of extra ports for infusion)

3) has anyone tried doing a smoke test to find leaks? using some kind of smoke which is sucked in from the feed line?

thanks
